100kPa and 22 °C air is contained in a rigid tank of 2 m3. There is supply line connected to the tank through a valve. If the valve opens, the air in the supply line with 600kPa and 22 °C flows into the tank. Valve is shut off when the tank air pressure reaches to 600kPa and the final tank air temperature is 77 °C.
