60. Oxygen mass m = 200g occupies a volume V1 = 100 l and stored under pressure P1 = 200 kPa. When heated gas expands at constant pressure to a volume V2 = 300 liters, and then the pressure is increased to p2 = 500 kPa at constant volume. Find the change in internal energy of the gas, and it work perfect amount of heat transferred to the gas.
