Question
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 Figure (a). The vertical scale is set by ps = 56.0 Pa, and the horizontal scale is set by Vs = 5.6 m3. (a) – (g) Show sign of values in the table in Figure (b) by depicting a plus sign, a minus sign, or a zero for each indicated cell. (h) What is the net work done by the system as it moves once through the cycle ABCA?
Q W Delta E int A -> B (a) (b) + B -> C + (c) (d) C -> A (e) (f) (g)Explanation / Answer
the net work done by the system = P(V2 - V1)
= 56.0 * 5.6
= 313.6 J
