Problem D9:
Consider a **monatomic** ideal gas that is confined to a container. The gas starts in the
state A. The gas then undergoes a quasi-static process to the state B that is shown in the
figure below. In state A the volume is n_{1}V_{0} and the pressure is P_{0}.
In state B the volume of the gas is V_{0} and the
pressure is n_{2}P_{0}. The process is as follows:
first A->B is isobaric (constant Pressure) to C, then C->B is isometric (constant
volume). If the energy transfered to the gas in the form of heat Q for
the whole process A->B is Q = n_{3} P_{0}V_{0},
what is n_{3}?
Note that n_{1}, n_{2} and n_{3} are unitless.
