An ideal gas is taken around a 3 state cycle abc. Process ab is isochoric, process bc can be isothermal or adiabatic and process ca is isobaric. States a and b are at fixed pressure and volume. Process c is done at a fixed pressure but can change volume depending on if b to c is done adiabatically or isothermally. What is the relation between the work done for this cycle if b->c is an adiabat vs if b->c is an isotherm?
