    How will you define the specific heat at constant volume?

    A)  The amount of heat required to raise the temperature of unit mass of gas through one degree at constant pressure

    B)  The amount of heat required to raise the temperature of 1 kg of water through one degree

    C)  The amount of heat required to raise the temperature of unit mass of gas through one degree at constant volume

    D)  All of the above

    Correct Answer: C

    Solution :

     The specific heat at constant volume \[\text{(}{{\text{C}}_{\text{V}}}\text{)}\] is the amount of heat required to raise the temperature of unit mass of gas through one  degree at constant volume. \[{{C}_{v}}=\frac{q}{m\times \Delta T}\] (at constant volume)
