The adiabatic exponent of a gas \(\frac{c_{p}}{c_{v}}=y\) and its molecular weight is M. The difference of its molar heat capacity and specific heat capacity (both at constant pressure) will be
- \(\frac{y R}{y-1}(M-1)\)
- \(\frac{y R}{y-1} \frac{(M-1)}{M}\)
- \(M\left(\frac{R}{y-1}\right)\)
- \(\frac{\mathrm{R}}{\mathrm{M}(\gamma-1)}\)
Answer
(D) R M ( -1)
