The Attempt at a Solution


The only ways I know of to calculate heat are dQ = Cp.dT and dQ = Cv.dT for isochoric and isobaric proccess how would you go about doing it for an isothermal process

Also if a system isnt a cycle but it ends up in the same state it started is its change in internal energy still 0

For an isothermal process with an ideal gas, the heat added (or subtracted - depending upon exactly what happens to the gas) is equivalent to the work done on (or by) the gas.
