Question
only par of it is wrong, please show me the correct answer, thanks
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 = 87.9 Pa, and the horizontal scale is set by Vg = 5.25 m3. (a) - (g) Show sign of values in the table in Figure (b) by depicting a plus sign 1, a minus sign -1 and a zero 0 for each indicated cell, (h) What is the net work done by the system as it moves once through the cycle ABCA?Explanation / Answer
Wnet = 1/2 * 2.625 * 43.95
= 57.68 J
Since process C to A involves larger negative work (it occurs at higher average pressure) than the positive work done during process A to B, then the net work done during the cycle must be negative.
The answer is therefore Wnet =
