8)

A system undergoes a reversible cycle that traces a triangle in the p

-

V plane. In the first leg of the cycle, the gas contracts at a constant pressure of

100

kPa from

30

L to

22

L; in the second leg, the pressure increases to

150

kPa, with the volume staying constant. In the third leg, the pressure and volume change so that the system follows the straight line that closes the triangle. How much heat is supplied to the system in each cycle?
