The pressure and temperature of an ideal...

The pressure and temperature of an ideal gas in a closed vessel are 720 Kpa and `40^(@)C` respectively. If `(1//4)^(th)` of the gas is released from the vessel and the temperature of the remaining gas is raised to `353^(@)C`. The final pressure of the gas is

1440 kPa

1080 kPa

720 kPa

540 kPa
