EXPERIMENT 302HEAT AND CALORIMETRYEd Paolo de las Alas, PHY12L/A7[email protected]AbstractThe experiment will be conducted to determine the specific heat of metals as well as the latent heat of fusion of ice. The specific heat of metals is determined by using the method of calorimetry as it determines the amount of heat quantitatively by utilizing the law of heat exchange. The heat capacity per unit of mass of a material or itself. In particular, it depends on the number of degrees of freedom that are available to the particles in the substance, each of which type of freedom allows substance particles to store energy.While as for the latent heat or the heat released or absorbed by a body or a thermodynamic system during a constant-temperature process. The term describes the direction of energy flow when changing from one place to the next. Also called the enthalpy of fusion, it isthe change in enthalpy resulting from heating a given quantity of a substance to change its state. The temperature at which this occurs is called the melting points. Commonly used in the field of thermodynamics and in designing materials wherein the system takes into account the changes that can be brought about by the change in temperature, the latent heat of fusion can also be used to predict solubility for solids in liquids.Key Words:Law of Heat Exchange, Heat capacity, Enthalpy, ThermodynamicsIntroductionHeat being a form of energy can be associated with calorimetry in such a way that the method of calorimety is also used with a purpose of deriving the heat or heat transfer associated with changes in which more likely are chemical reactions, physical changes and phase transitions. In calorimetry, it is often recommended to know the heat capacity of the calorimeter itself than that of the whole system because as the law of heat exchange states, the heat lost by the external system must be equal to the heat gained by the object.
