A vessel contains 7.1g chlorine gas at pressure P and temperature T K. On heating the vessel to 30 higher temperature, 246 mL of chlorine at 1 atm and 27C is taken out to maintain same pressure in vessel. Calculate:
(a) the original temperature,
(b) if the gas is not allowed to escape out, the pressure increases by 0.11 atm. Calculate the volume of vessel and initial pressure.
