An ideal gas with heat capacity at constant volume `C_(V)` undergoes a quasistatic process described by P`V^(alpha)` in a P-V diagram, where `alpha` is a constant. The heat capacity of the gas during this process is given by-

Options

A. `C_V`
B. `C_V+nR`
C. `C_V+(nR)/(1-alpha)`
D. `C_V+(nR)/(1-alpha^2)`

Answer

C

Explanation

Direct formula is to be used `C=C_V+(nR)/(1-alpha)`.
