2. 1.75 mole of an ideal gas with 61d4eeea0638d.jpg (heat capacity per mole at constant volume) is expanded adiabatically against a const external pressure of 1 bar. The initial temperature and pressure are 290 K and 19.5 bar. The final pressure is l bar.

(2) Calculate g(heat), w(work), △U (change in internal energy) and △H (change in enthalpy) for the process.
