Problem D10:
Consider an ideal gas that is confined to a container. The gas
undergoes the cyclic quasi-static process shown in the graph below. The cycle consists of
two isothermal processes (constant T) bounded by two isometric processes (constant V).
The gas starts off with a pressure of P_{0} and a volume of V_{0}.
The gas is first heated up with a constant volume to a pressure n_{2}P_{0}.
Then it expands isothermally to a volume e^{n1}V_{0}. Next it
cools down with a constant volume. Finally, it is compressed isothermally to its original
state. If the net heat energy given to the gas is Q_{net}=n_{3}
P_{0}V_{0}, what is n_{3}?
Note that n_{1}, n_{2} and n_{3} are unitless.
