One mole of an ideal mono-atomic gas is in a state A characterized by a temperature TA. The gas is then subjected to a succession of three quasi-static reversible processes: An isothermal expansion A → B, which increases the volume by a factor y. The expansion factor is therefore y = VB / VA> 1. An adiabatic compression B → C which increases the pressure by a factor w. The compression factor is w = pC / pB> 1. A...
