ANSWERS:

a. 3000J

b. 1000J

An ideal gas expands isothermally
from state A to state B. The gas
then cools at constant volume to
A
D
B
C
V
VA=V₁=2 liters
PA 10 atm
P = 2 atm
state C. The gas is then
compressed isobarically to D before it is heated until it returns to state A.
(a) What is the internal energy of the gas at point B?
(b) What is the net amount of work done after one complete cycle?
V=V=4 liters
T₁= 327 °C
