A cylinder contains an ideal gas at the temperature of 300 K and is closed by a movable piston. The gas, which is initially at a pressure of 3 atm occupying a volume of 30 L, expands isothermally to a volume of 80 L. The gas is then compressed isobarically, returning to its initial volume of 30 L. Calculate the work done by gas: a) in isothermal expansion; b) in isobaric compression, c) in the whole process; and d) Calculate the final temperature of the gas.

A vertical cylinder contains N molecules of a monatomic ideal gas and is closed off at the top by a piston of mass M and area A. The acceleration due to gravity is g. The heat capacities of the piston and cylinder are negligibly small, and any frictional forces between the piston and the cylinder walls can be neglected. The whole system is thermally insulated. Initially, the piston is clamped in position so that the gas has a volume V0...
