The figure represents the processes AB , BC and CA undertaken by a certain mass of an ideal gas. Along the path AB , the gas is isothermally compressed with release of 800 J heat to the surroundings. It is then compressed adiabatically along the path BC and the work done is 500 J . The gas then returns to the state A along path CA and absorbs 100 J heat from the surroundings. The work done by the gas along the path C
