if heat is added to a gas for the entire cycle, does that affect the net work done by the gas on its surroundings for the entire cycle?
 
Wbc=0 Wab=-3315.4J Wca=nRTLn(Va/Vc)=-2108.98

The net heat added to the gas for the entire cycle is 1200J. Determine the net work done by the gas on its surroundings for the entire cycle.


Don't you just add the works?
