Specific heat

water molecules water is given the following properties relating to heat and temperature :- 1. Relatively high heat capacity 2. Relatively large latent heat of vaporisation 3. Relatively large latent heat of fusion These three properties are very similar and basically mean that a relatively large amount of energy required to change the temperature or state of water. The specific heat capacity of water is 4184J/kg, over 40 times that of sodium chloride. This

Introduction/Purpose To determine whether boiling point, density, mass, and volume are intensive or extensive properties two experiments will be conducted. One experiment will be dedicated to identify if boiling point is an intensive or extensive property by boiling water at different quantities. The other experiment will identify if density and mass are intensive or extensive properties by utilizing a grape. The experiment will consist of measuring the mass and volume of a grape to determine the

Introduction/ Abstract: As a metal was being heated, the temperature was changing by increasing the heat capacity. The change of the temperature depended on how much heat was supplied to the metal and the mass, which could make a difference based on the object being heated. With that said, the purpose of this experiment, which covered the concepts of heat and calorimeter, was to measure the specific heat of a metal and to compare the experimental result to the theoretical value of same metal. Theory:

Introduction The aim of the experiment is measure the specific heat capacity of water and two metals, aluminum and copper respectively of different conductivity to heat. Heat is a form of energy associated with the motion of atoms or molecules and is capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation. It could also be defined as the transfer of energy from one body to another as a result of the difference

Scottish chemist Joseph Black first introduced the term ‘Latent Heat’. He defined this term as the quantity of heat absorbed or released by a substance undergoing a change of state at a constant temperature and pressure [2]. Black, used the term latent heat in the context of calorimetry [3] when he observed a change in volume of a thermodynamic system whilst it was held at a constant temperature. Two more common forms of enthalpies are latent heat of fusion (solid to liquid) and latent of vaporization (liquid

Introduction Specific heat capacity is defined as the amount of heat needed to raise the temperature of a unit mass of any substance by one degree centigrade. In order to determine the heat that flows in a physical process, it is important to determine the calorimetric constant for the dewar flask calorimeter. Determination of Calorimetric Constant Whenever a body undergoes a change in its chemical or physical nature, change in energy occurs. This change is commonly observed as heat flows from

Heat Transfer Lab Assignment SCH 4U1 Brad Bonner Mrs. Hsia August 30, 2017 Question: How does increasing the temperature of water affect the temperature of the entire solution? Hypothesis: If the temperature of the water increases, then the temperature of the entire solution slowly increases because there is an increase in kinetic energy in water, so when thermal equilibrium is reached, the temperature of the solution is higher and the water exchanges the heat with compound Y and

substance that transfers heat poorly, meaning it traps the heat of what it contains. (InnovateUs). A material is either an insulator or a conductor, which is the opposite of an insulator: a material that transfers heat efficiently. What classifies these materials into these two categories are their specific heats. Specific heat is “the amount of heat per unit of mass required to raise the temperature [of a substance] by one degree Celsius,” (GSU). The higher the specific heat, the more thermal energy
