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 = 44.0 Pa, and the horizontal scale is set by Vs = 4.4 m3. (a) - (9) Show sign of values in the table in Figure (6) 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? c Ps Pressure (Pa) A 0 W Ant B B (a) (b) + B + (c) (d) 0 V, A (e) (g) (a) Volume (m) (b) (a) (b) I to (c) (d) (e) (6) (g)
