A hollow cylinder made of thermally insulating material is equipped with a horizontal piston P of mass m and area A The piston is also made by thermally insulating material There is no friction between inner surface of the cylinder and the piston Above the piston a liquid of density p is filled up to the brim of the cylinder The piston supported at the position shown due to pressure of an ideal gas filled in the bwer portion of the cylinder When the gas is heated by the heater H it expands and pushes the piston up spilling the water out of the cylinder Number of moles of the gas is n atmospheric pressure is po and initial temperature is To A Work done by gas is pohA 0 5pgh2 A mgh B Work done by gas is 0 5 pohA pgh A meh C Final temperature of the gas is 2T D Final temperature of the gas is 2T PO A PoA pghA mg Po A mg ROA pehA me P H 0000
