A lab sample of gas is taken through cycle abca shown in the p–V diagram of Figure. The net work done is +1.2 J. Along path ab, the change in the internal energy is +3.0 J and the magnitude of the work done is 5.0 J. Along path ca, the energy transferred to the gas as heat is +2.5 J. How much energy is transferred as heat along

(a) Path ab and

(b) Pathbc?
