Experiment

Aim: To find the specific heat capacity of three different metal using the method of mixtures.

Specific Heat Capacity – It is the amount of heat (thermal) energy required to cause a rise in temperature by 1°C in a solid of 1kg.

Apparatus: 1. Metal cubes (3) 2. Beaker 3. Water bath 4. Thermometer (L.C. 1°C) 5. String 6. Digital Balance

Risk Assessment: 1. Wear a lab coat to prevent any substance from falling you and potentially harming you. 2. Be careful when transferring metal from water bath to beaker as the water may fall and could burn you. If this scenario arises then put affected part under running cold water.

Method: 1. Gather all required apparatus 2. Suspend the metal using the string into the water bath 3. Use the digital balance to measure the mass of the empty beaker 4. Pour water into the beaker 5. Measure the mass of the beaker containing water and find the difference between the two which will be the mass of the water and record the values 6. Measure the initial temperature of the water 7. Measure the initial temperature of the metal 8. Transfer the hot metal into the beaker 9. Monitor the change in temperature of the mixture and record the initial increase of the water when it stabilizes 10. Remove the metal from the beaker and find its mass 11. Using the formula E=MC (change in temperature) to find the total energy transferred in water 12. Since this is equal to the enrgy transfer in the metal you can determine the enrgy transferred in the metal.

Observation: | Copper | Aluminum | Brass | | 1 | 2 | 1 | 2 | 1 | 2 | Mass of empty beaker (g) | 87.3 | 87.3 | 87.3 | 87.3 | 87.3 | 87.3 | Mass of beaker with water (g) | 218.9 | 218.8 | 213.8 | 212.6 | 213.25 | 212.7 | Mass of water (g) | 131.6 | 131.5 | 126.5 | 125.3 | 126 | 125…...

Heat Changes Experiment Report

...Aim: To investigate the correlation between the concentrations a base and enthalpy change in a heat of neutralization reaction. Variables: * Independent: mass of baking soda (NaHCO3) * Dependent: temperature of the product * Control: concentration of CH3COOH (0.4mol), volume of CH3COOH (100ml), volume of water (10ml) Theory: Q = mc T and H = - Q/n The enthalpy change, H is the amount of heat released or absorbed when a chemical reaction occurs at constant pressure. The heat energy (Q) is measure of the total energy in a substance and does depend on the amount of substance present. Since the value of H depends on the mole (n), and the bigger the mole number the smaller the value of H will be. The neutralization reaction HC2H3O2 + NaHCO3 = CO2 + NaC2H3O2(aq) + H2O(l) releases heat therefore it is an exothermic reaction. The energy of the reactant is greater than the product (Hproduct > Hreactant) This is because there is net bond formation. The products collectively have lower energy than the reactants. Evaporation of the liquid occurs as the carbon dioxide escapes from solution. Evaporation absorbs heat, cooling the liquid. The CO2 gas will cause foam and bubble in this reaction. (CH3COONa) in water (H2O), as the carbon dioxide gas (Co2) escapes. Hypothesis: The higher the concentration of baking soda added to the reaction, the smaller the H value will be.

Specific Heat

...vapour to the rest of the system. It accomplishes this by separating the water (refrigerant) from the lithium bromide-and-water solution. In the generator, a high-temperature energy source, typically steam or hot water, flows through tubes that are immersed in a dilute solution of refrigerant and absorbent. The solution absorbs heat from the warmer steam or water, causing the refrigerant to boil (vaporize) and separate from the absorbent solution. As the refrigerant is boiled away, or “generated,” the absorbent solution becomes more concentrated. The concentrated absorbent solution returns to the absorber and the refrigerant vapour migrates to the cooler condenser. Physically, the generator and condenser are contained inside of the same shell. The pressure in the condenser section is less than the pressure in the generator section. This is because the temperature of the cooling water flowing through the tubes of the condenser is less than the temperature of the steam or hot water flowing through the tubes of the generator. Inside the condenser, cooling water flows through tubes and the hot refrigerant vapour fills the surrounding space. As heat transfers from the refrigerant vapour to the water, refrigerant condenses on the tube surfaces. The condensed liquid refrigerant collects in the bottom of the condenser before traveling to the expansion device. From the condenser, the liquid refrigerant flows through an expansion device into the evaporator. The expansion......

Experiment 12: Determination of the Enthalpy (Heat) of Reaction of a Monobasic Acid with Sodium Hydroxide

...Title of Experiment: Determination of The Enthalpy (Heat) of Reaction of A Monobasic Acid with Sodium Hydroxide No. of Experiment: 12 Date of Experiment: 2/2/2016 Date of Submission: 24/2/2016 Group members: 1)Chong Chi Wei 2)Mong Lai Wan 3)Ang Yen Yuan Name of Lecture: Dr. Sim Yoke Leng Title: Determination of the Enthalpy (Heat) of Reaction of A Monobasic Acid with Sodium Hydroxide Objective: 1. To understand the enthalpy chemistry. 2. To determine the calorimeter constant. 3.To determine the enthalpy of reaction of acid-base reactions. Introduction: Heat is associated with nearly all chemical reactions. In such instances, the reaction either liberates heat (exothermic) or absorbs heat (endothermic). When a reaction is carried out under constant pressure (as in an open beaker) the heat associated with the reaction is known as enthalpy. The symbol for enthalpy is ΔH. It is most often too difficult to direct measure the enthalpy change for a reaction. What can be done is to measure the heat changes that occur in the surrounding by monitoring temperature changes. Conducting a reaction between two substances in aqueous solution, allows the enthalpy of the reaction to be indirectly calculated with the following equation. q=m x c x Δ t The term q represents the heat energy that is gained or lost. C is the specific heat of water, m is the mass of the water and Δ t is the temperature change of the reaction mixture. The specific heat......

Heat and Temperature

...Running head: Study Of Heat Heat and Temperature Marcus A. Bullock SCI 110 Intro to Physical Science The Study Of Heat and Temperature Heat is a function of the velocity of all the molecules of a substance. Kinetic theory and heat transfer are both in motion, in Kinetic theory all states of matter are in vigorous motion and heat transfer is associated with the motion of atoms or molecules. The kinetic theory of matter says that all matter is made of particles that are in constant motion. Matter is made of constantly moving particles, which tells us how the matter in solids, liquids, and gases behaves. The reason heat relates to the kinetic theory is because, gases consist of great numbers of molecules moving in all directions, that their impact on a surface causes the gas pressure to rise. Heat study is explained through the movement of warmer and cooler objects, the changing of temperature. It is not a theory of sorts like kinetic theory of matter is. Scientist state that heat is defined as “something” that moves between objects when two objects of different temperatures are brought together. The more heat that is produced the higher the kinetic energy level of an object or substance it has. Temperature on the other hand, can be defined as the degree of hotness or coldness of an object. Temperature is the measure of the average heat or thermal energy of particles in a substance. The relationship between heat and temperature is......

Heat

...Running head: HEAT 1 Heat Adrienne Branch Professor Olivia Uitto Science 110- Introduction to Physical Science April 27, 2012 HEAT 2 How does the study of heat relate to the kinetic theory of matter? The philosophers Democritus and Lucretius stated that matter is composed of particles. They also believed that these particles were in constant motion and in the state of solid, liquid, or gas (Gibbs, 2010). They called this theory the Kinetic Theory of Matter after the word kinema, which is Greek (Gibbs, 2010). In the study of heat we learn that whenever heat is added to a substance, molecules and atoms vibrate faster. Due to the quickly vibrating atoms, the area between the atoms get larger (“Atoms and Molecules”, n.d.). The state of the matter of the particular substance is determined by the motion and space between the particles. The more an object expands, the more space it takes up (“Atoms and Molecules”, n.d.). During this process, the mass of the particular object will not change. Solids, liquids, and gas all expand when heat is added. When an object cools, molecules vibrate at a slower pace. The atoms start moving closer together again and the matter begins to contract. During this process as well, the mass will remain the same (“Atoms and Molecules”, n.d.). Several good examples of the Kinetic Theory of Matter relating to heat is with sidewalks and railroad tracks which are solids. They......

Heat

...“How does the study of heat relate to the Kinetic of matter?” Heat is transferred into motion. This is done by kinetic matter. It moves at a rapid motion, making the heat that’s being transferred combine with the motion of atom and molecules. Therefore, matter takes on changes when heat is constantly being applied. For this reason, the process is called the kinetic theory. Heat takes on 3 stages and they are solid, liquids and gases. Solids forms there shape by arrangements of molecules. For example, ice has a shape but, changes when melting. Solids form around a fixed close position fitting making it stronger and Causing solids to maintain its shape. Liquids are closer together but, will change its form because space is provided. Gases are higher and 10 times the distance between that of solids and liquids. Therefore, allowing the particles to move freely and use the space available to them. “What is heat?” Heat can be describing that something that move between object when 2 objects of different temperature are brought together or energy transfer that move between object of different temperature (energy transfer). For example, when you rub your hand together, then you will feel the heat (warm) in center of your hand. There are two kind of energy. It’s call “External energy” and “Internal energy”. External energy is define as the total potential and kinetic energy of an everyday-sized object. Internal energy is the total kinetic and potential......
