Question

Chapter 19, Problem 061 A gas is to be expanded from initial state i to final state f along either path 1 or path 2 on a p-V diagram. Path 1 consists of three steps: an isothermal expansion (work is 39 J in magnitude), an adiabatic expansion (work is 17 J in magnitude), and another isothermal expansion (work is 30 J in magnitude). Path 2 consists of two steps: a pressure reduction at constant volume and an expansion at constant pressure. What is the change in the internal energy of the gas along path 2?

Explanation / Answer

the internal energy of the gas along path 2 is an adiabatic expansion

so

heat energy dQ = 0

the internal energy of the gas along path 2 is -17 J
