A gas is expanded from volume V_(0) = 2V_(0) under three different processes. Process 1 is isobaric process, process 2 is isothermal and process 3 is adiabatic. Let DeltaU_(1), DeltaU_(2) and DeltaU_(3) be the change in internal energy of the gas in these three processes. then

Two moles of helium gas ( gamma = 5 / 3 ) are initially at 27^@C and occupy a volume of 20 litres . The gas is first expanded at constant pressure until the volume is doubled.

A weightless piston divides a thermally insulated cylinder into two parts of volumes V and 3V. 2 moles of an ideal gas at pressure P = 2 atmosphere are confined to the part with volume V =1 litre. The remainder of the cylinder is evacuated. The piston is now released and the gas expands to fill the entire space of the cylinder. The piston is then pressed back to the initial position. Find the increase of internal energy in the process and final temperature of the gas. The ratio of the specific heats of the gas, gamma =1.5 .
