(a) Consider the adiabatic reversible expansion of 0.02 mol of ammonia (NH3) from 0.50 dm to 2.00 dm. The initial temperature was 25 °C. Molar heat capacity of NH3 at constant volume is 28.0 J K- mol. Calculate the final temperature, the work done, and the change of internal energy for the thermodynamic process.
