ANSWER ALL PARTS As shown in the pV diagram, an ideal gas moves through a cycle from A to B to C and then back to A. From state A to state B, the ideal gas absorbs 80.0 J of heat and its internal (i.e. its thermal) energy increases by 30.0 J. From state B to state C, the internal energy of the ideal gas decreases by 20.0 J. As such, determine the following quantities: B V The work done...
