Argumentative essay

Many generations have believed that adding salt to water will help it boil faster, even your mum does it but does it really help?When testing this experiment we found that 25g of salt would change the solution of 1l of water . we found that you have to use the same heat source for this experiment to make sure that the results stay constant and after that you have to allow for your heat source to cool. The boiling temo of water is 100 d C but when water is added the solution is changed so much that it increases the boiling tempreture buy two degrees (mental-floss,2005) Infact, adding salt to your water does not lessen time taken to boil water

Adding salt to water can increase the time taken to boil by up to 30 seconds. While experimenting we found that the time increased the time but up to 30 seconds. this can be proven in our results that were done numerous times to prove our theory and eliminate human error. Going up un 15g gave us and idea of how much it changes per 15g . the first 15-25 g there was very little change, this being said it changed by 5 – 10 seconds. And at 75g of salt we saw out biggest change of about 30s
At 75g it reaches equilibrium and after that , no amount of salt added would change the time. We tried adding 100g salt to the 1l of water but found that the average boiling time stayed the same as the 75g of salt before. This is because in every solution at one point it will reach constant and at this point only changes to the amount of water would change the outcome
Claim3

Thus proving that by adding salt to water it is not speeding up boiling time but rather slowing it down. This shows that in all the years that your mother was trying to speed up her cooking time , she was actually just slowing herself…...

Water Purification

...------------------------------------------------- Water purification From Wikipedia, the free encyclopedia This article is about large scale, municipal water purification. For portable/emergency water purification, see portable water purification. For industrial water purification, see deionized water. For distilled water, see distilled water. For the treatment of sewage see sewage treatment Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacological, chemical and industrial applications. In general the methods used include physical processes such as filtration,sedimentation, and distillation, biological processes such as slow sand filters or biologically active carbon, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light. The purification process of water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria,algae, viruses, fungi; and a range of dissolved and particulate material derived from the surfaces that water may have made contact with after falling as rain.

Salt Water Assignment

...Chemistry Assignment: Boiling Water Mrs. Goodyer Due Date: 21 July, 2006 Ben Graham Aim: To observe whether salt levels in water will alter boiling temperatures and times. Hypothesis: I hypothesise that adding salt to the water will raise the boiling temperature of water and lessen the time it takes to boil. This hypothesis is due to the ebullioscopic constant of water and the high heat capacity of water and low heat capacity of salt. Equipment: Beaker or saucepan Bunsen burner or hotplate Thermometer 45 grams of salt Stopwatch or timer Method: A saucepan was filled with 100ml of water. Its temperature was observed and recorded before the saucepan was placed on the hotplate. The timer was started as soon as it touched the hotplate. The thermometer was held in the water, not being allowed to touch the bottom of the saucepan. Every 30 seconds, a reading was recorded from the thermometer. Once the reading had been the same for one and a half minutes, the experiment was stopped. The experiment was repeated 4 times in total. The experiment was then repeated, but 15 grams of salt was added before heating started. Again, it was repeated, but with 30 grams of salt. The recorded results were then categorised, organised and displayed in appropriate......

Boiling Water

...Effect of Table Salt on Water Reaching 99⁰ C Abstract I had always been told that, when cooking, adding salt to water would make the water boil faster. Recently I had heard that this wasn’t true. Beginning with the hypothesis that salt did increase the boiling time, I set out to discover if this was the case. Using the home stovetop, I boiled 2 liters of water each time and the amount of salt added was the control. The experiment was to find out how long it took the water to reach 99⁰ Celsius. After 8 boils at four different salt concentrations, the effect on the time to reach the desired temperature was negligible. The water was already boiling each time the temperature achieved the target. The experiment seemed to indicate the salt has no effect on the time it takes water to reach 99⁰ C. Background As mentioned in the abstract, I had been led to believe that adding even a “pinch” of salt to water would accelerate the time that water would reach boiling. However, this was challenged recently and I was curious if I had been told a “wives tale” all my life. I have no chemistry background, but since the experiment, I have a better understanding of what should have occurred because of the added solvent (NaCl in this case), which will be addressed in the conclusion. Design Eight experiments were run using four measurements of table salt in 2 liters of tap water. Care was taken to ensure each of the variables, other than the control variable of salt, remained......

Changes of Australian Exchange Rate

...Analyse the effects of changes in the exchange rate of the Australian dollar against other currencies on the Australian economy The exchange rate is the rate at which a unit of domestic currency is exchanged for a given amount of a foreign currency. The exchange rate may be measured bilaterally, against another currency, usually that of a trading partner, e.g. the US, or it may be measured as the Trade Weighted Index – against a basket of currencies of Australia’s trading partners weighted according to their importance in Australia’s trade. As Australia has a floating exchange rate, the value of the AU$ is determined by forces of demand and supply in the forex market. The exchange rate fluctuates in order to maintain equilibrium. These changes are known as appreciation and depreciation. An appreciation is when the value or purchasing power of the AU$ rises, whilst a depreciation is when it declines. An appreciation in the AU$ will occur if the demand for the AU$ exceeds the supply. This may be due to either an increase in demand or a decrease in supply. The graph below shows that a shift to the right (increase in demand) of the demand curve has led to a rise in the $Au from $0.70 US to $0.75 US. This may be the result of a rise in world growth, leading to a rise in the demand for Aust exports. >>graph<< The graph below shows demand a shifting to the left, and therefore a decrease in demand. It can be seen that this has led to a rise in equilibrium......

Compare and Contrast Fresh and Salt Water Fishing

...As an avid shore fisherman who enjoys fishing, I have the unique opportunity to choose between two similar, but two very different, types of fishing. These two types of fishing are fresh water fishing and salt water fishing. With that being said, in the state where I reside, there are two distinct attitudes towards fishing. There are those anglers who prefer fresh water fishing, and there are those anglers who prefer salt water fishing. Both types of fishing ultimately deal with utilizing a fishing pole, fishing line and bait (or a fishing lure) to catch fish. However, in the same way they are similar; in contrast, they are both very much different. In a fresh water lake, the water rises with the amount of rainfall and falls due to evaporation and drainage; on the other hand, ocean the water rises and falls with the lunar tide. Unlike fresh water fishing, where an angler would use “lighter” fishing tackle due to catching smaller fish, salt water fishing requires much “heavier” tackle due to the vast difference in size from fresh water fish to salt water fish. For instance, the State record for a fresh water largemouth bass caught in a lake is 10 pounds 14 ounces; whereas, a Great White shark can weigh more then a car! So as you can see, although fresh water fishing and salt water fishing are similar, in some ways, they are very much different. Works Cited Houch, R. (September 3, 2013). NJ Saltwater Fisherman.

Changes in Divorce Rates

...Examine the changes in divorce rate since 1969 Divorce has gradually become a norm in society since 1969. There are a few factors which have led to this; legal changes which have given women more independence when it comes to marriage and divorce and there is a lot less stigma attached to people who get divorced especially women, which is a view supported by Liberal Feminists also rising expectations of marriage has also lead to more divorces and the general serculisation of modern day society has led to an increase in divorce. The changes in law that made more accessible to file for divorce have certainly contributed to the sharp increase from 1969; The Divorce Reform Act meant that couples could file for divorce if their marriage was deemed irretrievable and this act opened the door for people to freely get divorced. The 1984 Family law act further gave married couples an easier route to marriage because it allowed marriage after only one year of marriage so people didn’t have to stay in a broken down marriage for 3 years before getting a divorce, this had an effect on the increase of divorce because people were less patient with dysfunctional marriages because they would be wasting time trying to find there ‘true love’. Functionalists such as Ronald Fletcher would say that high divorce rates are due to people over expectations of married life and viewing it as a romantic idea out of a love story and most of the time it’s not the same in reality. In the past there......

Changes in the Rate of Divorce

...Item B and elsewhere assess sociological explanations of changes in the rate of divorce. Divorce means the legal termination of a marriage. The rate of divorce rose rapidly from the 1940s to the 1990s where it has levelled off at a rate of about 40% of marriages end in divorce. Sociological explanations focus on changes to the laws, the role of women, secularisation, changing expectations of marriage, and changes in society itself. Item B suggests that the British marriage pattern is similar to trends in other European countries, especially those that are less religious. This may be explained by the idea that people in religious societies are more likely to stay in empty shell marriages rather than get divorced as this is either impossible or frowned upon by the church. This means that the higher divorce rate may not reflect any change in the level of relationship breakdown but simply the opportunities available to couples to separate when their relationship has failed. Older people tend to stay in empty shell marriages because they don’t want all the hassle of getting a divorce. Secularisation may have had an impact in changes on the law. As religion became less important the state felt it could pass laws to make divorce easier. Some New Right theorists have argued that laws have made it too easy to get a divorce. Indeed, when changes such as the 1948 Divorce Act made it possible to get legal aid the divorce rate shot up, just as it did again in the 1970s when......

The Buoyancy of Salt Water

...Q. Ogleby The Buoyancy of Salt Walter Introduction: Those who have swam in the ocean water can related to the difference in fresh and salt water. Children visit the beach often and will relate to the difference of the water in a pool and beach water. Besides the difference in taste we will explore the buoyancy force of salt water, which allows things to float with greater ease than is possible in fresh or pool water. Children will also learn that ships also are known to ride higher in salt water than in fresh water. The buoyant force of salt water can be demonstrated in the classroom using tap water to which table salt has been added. Learning Objectives: As a result of the demonstration lesson, students should * Understand the concept of density. * Develop an awareness of relative density as it relates to an object and the water in which it is placed. * Relate the demonstration to other situations that illustrate relative density like ships at sea. * Explain the floating and/or sinking of an object in water in terms of key works: density, buoyancy, and relative density. Materials Required: 1. 2 drinking glasses 2. tap water 3. table salt 4. 2 fresh eggs Presentation: 1.

Salt and Water Volume

...Connection Between Salt and Water Volume and in Blood Pressure Changes Salt (sodium) is essential to our bodies. Normally the kidneys control the level of salt. If there is too much salt, the kidneys pass it into urine. But when our salt intake levels are very high, the kidneys cannot keep up and the salt ends up in our bloodstream. Salt attracts water. When there is too much salt in the blood, the salt draws more water into the blood. More water increases the volume of blood which raises blood pressure. Some people are more sensitive to salt than others. In some people too much salt will cause their blood pressures to rise, in others there will not be as large a change. About half of people are salt sensitive. African-Americans, the elderly and people with diabetes are more often salt sensitive. If you have high blood pressure, you can always benefits from decreasing your salt intake. Sodium has an important influence on blood pressure, but we are not sure exactly how it works. Since the systems that control blood pressure include dozens of complex vascular, neurological, and hormonal elements. Although the body can rid itself of excessive dietary sodium, it seems likely that eating salt expands your blood volume, at least to a subtle degree. In turn, the extra volume may signal your kidneys to trigger a cascade of hormonal and vascular effects that raise blood pressure. And some experts suspect that these hormones may have adverse effects on vascular health even if blood......

Does Salt Effect the Boiling Point of Water

...Does Salt effect the Boiling Temperature of Water? By Jason Project Design Plan Water freezes at 32°F and boils at 212 °F. Dissolved substances such as salt lower the freezing point of water. This is why salt is sprinkled over icy pavement or wet roads in winter. It causes the temperature of the water to reach less that 32°F to form ice. Does it also have an effect on the boiling point of water? Does the quantity of salt added effect the boiling point? My experiment is to find out what effects salt will have on the temperature of boiling water. The hypothesis of my experiment is that if I add more salt then the temperature of the boiling water will increase. I believe the more salt added to the water the higher the boiling temperature is going to be. I will be using 2 cups of water as a base in a 2 quart stainless steel pot. I will add 1 tsp of salt, 2 tsp of salt and 4 tsp of salt and measure the temperature of the water. Literature Review If you heat up two pots of water one with tap water and one with tap water and 20 percent salt water, the pot with the salt water will boil before the pot without salt water. The heat capacity of water is higher than salt water. This means that it takes less energy to increase the temperature of salt water than it does unsalted water. Thus salt water warms up quicker and gets to a boiling point faster than unsalted water. (Dammann, 2013) Dissolving table salt into water will lower the overall vapour pressure......

The Effects of Changes in Foreign Exchange Rates

...The Effects of Changes in Foreign Exchange Rates By: Benjamin T. Givens INTRODUCTION Over the past few decades, different generally accepted accounting principles (GAAP) have been developed in various countries. These differences have arisen in response to the unique legal, regulatory, litigious, social, economic, religious, and cultural environments of the countries they were created in (Wiecek and Young, 1-2). The increase in globalization coupled with related regulations has given rise to the need for a common set of global accounting standards – International Financial Reporting Standards (IFRS). Leading the charge, the International Accounting Standards Board (IASB), formerly known as the International Accounting Standards Committee, has begun a movement toward harmonization and convergence of GAAP. More than 100 countries currently use IFRS, so if your business goals include global expansion, it is critical to educate yourself about the impact of IFRS on your financial reporting processes and business now (U.S. GAAP vs. IFRS). This paper will focus specifically on the differences and similarities between IFRS and U.S. GAAP with respect to accounting for the effects of changes in foreign exchange rates. The guidance related to accounting for foreign currencies in U.S. GAAP is included in Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 830, Foreign Currency Matters. In IFRS, the guidance related to accounting for foreign...

Salt

...Salt What is it exactly? Salt is the residual left when waters from ancient oceans evaporated in shallow seas or marginal basins. http://www.waterencyclopedia.com/Mi-Oc/Mineral-Resources-from-the-Ocean.html Where is it found or used geographically? It is found in salt mines or in shallow water that is mineral rich. http://en.wikipedia.org/wiki/Salt How is/was it used? Salt is used in many different ways. Salt is used in the seasoning or flavoring of food while it also can be used to preserve it. People use salt to put on road during icy weather to keep traction on the roads so people do not slide while driving. Instead of using harsh chemical around your house to clean with salt is another option that can be used. Many people think salt is bad for your health while in fact it can help your body when using it right. A common example is gargling salt water when having a sore throat as long as you spit it out and not drink it. http://impossible2possible.com/bolivia/thickboxes/salt_uses.php http://en.wikipedia.org/wiki/Salt Who discovered it? There is not a specific person that can be named for the discovery of salt. But evidence has found early evidence of its use. The earliest one date back to about 8,000 years ago.

Water and Adaptation to Climate Change in the Arab Region

...WATER AND ADAPTATION TO CLIMATE CHANGE IN THE ARAB REGION Introduction Climate change (CC) refers to a change in the state of the climate that can be identified by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer. It refers to any change in climate over time, whether due to natural variability or as a result of human activity (IPCC ,2007). Science established a causal effect between the acceleration of Green House Gas (GHG) emissions and CC effects (IPCC ,2007), Global GHG emissions due to human activities have grown since pre-industrial times, with an increase of 70% between 1970 and 2004. Among the world’s regions, Arab region is especially vulnerable to climate change. It is one of the world’s driest, most water-scarce regions, depends on climate-sensitive agriculture. Per capita renewable water resources in the region, which in 1950 were 4,000 m3 per year, are currently 1,100 m3 per year. Projections indicate that they will drop by half, reaching 550 m3 per person per year in 2050.( World bank, 2006). In addition, climate-induced resource scarcity could further tensions in the region’s conflict-ridden areas, potentially escalating violence and political turmoil even beyond the region’s boundaries. This is supported by the fact that 80% of surface water resources and 66 % of total water resources in the Arab region is a shared water esources. Climate change is putting......
