Heat capacity is an important thermodynamic properties of substances in one of the purpose of calculating at a measured process or other process to join or release the heat, to be aware of the nature. Heat capacity is defined as: the quality of the flats once the object increased the heat, That type of mathematical

in the Formula dqthe joined or emited heat

the units of the heat capacity is J(kgK)

The heat capacity than the material and conducted by the process. Engineering applications are commonly used constant pressure specific heat capacity than CD set and two heat Cp, constant pressure heat capacity Cp units is the quality of the material in the same specific volume under the conditions of temperature units Changes in the release or absorption of energy; constant volume heat capacity Cv unit is the quality of the material in the same specific volume under the conditions of units when the temperature changes in the release or absorption can.
