Question:medium

For ideal gas: \(n\): number of moles, \(C_v\): molar specific heat at constant volume, \(\gamma\): adiabatic exponent of gas, \(T_f\): final temperature, \(T_i\): initial temperature, \(R\): gas constant. Assertion : \[ nC_v(T_f-T_i)=\frac{nR}{\gamma-1}(T_f-T_i) \] Reason : \[ \gamma = 1 + \frac{2}{f} \]
