Heat Capacity at Constant Volume (Cv)

The heat capacity at constant volume (Cv) quantifies the amount of heat required to raise the temperature of a system by one degree Celsius at constant volume. This formula uses two parameters: n, which indicates the number of moles of the gas, and CvM, which represents the molar heat capacity at constant volume (J/mol*K). The product of these two parameters gives Cv, the total heat capacity at constant volume, in Joules per Kelvin (J/K).

Heat capacity is an important concept in thermodynamics and is crucial for understanding energy changes within physical systems. It is particularly significant in processes such as heating and cooling where temperature regulation is necessary, and in calculating the energies involved in phase transitions.
