A sample of `3.0` mole of perfect gas at `200 K` and `2.0 atm` is compressed reversibly and adiabatically until the temperature reaches `250 K`. Given that molar heat capacity at `27.5 J K^(-1) mol^(-1)` at constant volume calculate `q,W,DeltaU,DeltaH` and the final pressure and volume. |

Answer» Correct Answer - `q=zero, W=+4.157 kJ,DeltaU=+4.157 kJ`, `DeltaH=5.372 kJ,5.2 atm,11.8 litre` |
