ideal gas at 627°C and 300 kPa. The other side of the tank is evacuated and the volume
is one-half the size of the part containing the ideal gas. The gas expands to fill the entire
tank when the partition is removed. Heat is supply to the gas until the temperature
increased to 1500°C. Calculate the final pressure of the gas (kPa).
