Specific heat at constant volume, cv: The energy required to raise the temperature of the unit mass of a substance by one degree as the volume is maintained constant.
Specific heat at constant pressure, cp: The energy required to raise the temperature of the unit mass of a substance by one degree as the pressure is maintained constant.

The equations in the figure are valid for any substance undergoing any process.
•cv and cp are properties.
•cv is related to the changes in internal energy and cp to the changes in enthalpy.
•A common unit for specific heats is kJ/kg·°C or kJ/kg·K. Are these units
