Initially, 1 kg of air at 101 kPa and 700 K is contained in a rigid tank. The tank is not insulated and cools down, as  result of heat transfer to the atmosphere (T_atm = 25° C, P_atm = 101 kPa), until it reaches thermal equilibrium. Determine the final pressure (kPa) and the heat transfer (kJ) for the process.
