A gas is to be expanded from initial state i to final state falong either path 1 or path 2 on a p-V diagram. Path 1 consists ofthree steps: an isothermal expansion (work is 40 J in magnitude),an adiabatic expansion (work is 20 J in magnitude), and anotherisothermal expansion (work is 30 J in magnitude). Path 2 consistsof two steps: a pressure reduction at constant volume and an expansionat constant pressure.What is the change in the internal energyof the gas along path 2?
