...thermodynamical cycle? Consider a thermodynamic cycle, where 1: the pressure increases from P to 2P isovolumetrically. Then 2: the gas expands on the diagonal line. Then 3: the gas compresses from 2V to V isobarically. Consider the temperature at the point (P,V) to be T. There are n molecules of gas. How much work is done on step 2?
A) 0
B) - PV/2
C) -PV
D) -3PV/2
E) -2PV
My answer:
I think the answer is -PV/2 since we have to measure the area in the cycle.
