Specific Heat Capacity

Basically, the First Law of Thermodynamics is a statement of the conservation of energy - the Second Law is a statement about the direction of that conservation - and the The heat capacity of the calorimeter must be obtained from a separate calibration experiment for example, a heating element can be used to introduce a known amount of heat. The specific heat capacity of water is know 4. Use a calculator, and round to the nearest hundredth place. A calorimeter is an insulated container that allows heat flow between substances, but does not allow heat to escape. Part A. Calorimetry is a method of measuring heat transfer within a chemical reaction or other physical processes.

In thermodynamics , the specific heat capacity symbol c p of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. Informally, it is the amount of energy that must be added, in the form of heat , to one unit of mass of the substance in order to cause an increase of one unit in temperature. The specific heat capacity often varies with temperature, and is different for each state of matter. The specific heat of a substance, especially a gas, may be significantly higher when it is allowed to expand as it is heated specific heat at constant pressure than when is heated in a closed vessel that prevents expansion specific heat at constant volume. Specific heat relates to other intensive measures of heat capacity with other denominators.
