Halliday, Resnick & Walker — Temperature, Heat, and the First Law of Thermodynamics: Problem 10

10 A thermodynamic system is taken from state A to state B to state C, and then back to A, as shown in the p-V diagram of Fig. 18-27a. The vertical scale is set by $p_s = 20 \text{ Pa}$, and the horizontal scale is set by $V_s = 2.0 \text{ m}^3$. (a)–(g) Complete the table in Fig. 18-27b by inserting a plus sign, a minus sign, or a zero in each indicated cell. (h) What is the net work done by the system as it moves once through the cycle ABCA?
