A lab sample of gas is taken through cyclic abca shown in the P-V diagram of fig 21-22 the net work done is + 1.5 J . Along paths Ab the change in the internal energy is +3.0 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) path bc ?

Text Solution

Verified by Experts
