1. One mole of N₂(g) at 298 K expands adiabatically from a volume of 5.0 atm to 1.0 atm in following two conditions: (a) reversibly, and (b) against a constant external pressure of 1.0 atm. The molar heat capacity at constant volume is equal to 5R/2. Determine the values of final temperature of N₂(g), for conditions (a) and (b). R = 8.314 J = 0.082 L atm
