Define specific heat capacity at constant volume.

Explanation

(i) The amount of heat energy required to raise the temperature of one kg of a substance by 1 K of `1 ^@ C ` by keeping the volume constant is called specific heat capacity at constant volume .
(ii ) the amount of heat required to rise the temperature of one mole of a substance by 1 K `1^@ C ` at constant volume is called molar specific heat capacity at constant volume .
(iii ) application of law of equiparition energy in specific heat of a gas Meyer.s relation `C_P -C_V =R ` concects the two specific heats for one mole of an ideal gas .
Equipartition law of energy is used to calculate the value of `C_P - C_V ` and the ration between them `gamma = (C_p )/( C_V) ` here ` gamma ` is called adiabatic exponent .
