An ideal gas is enclosed in a cylinder by a movable frictionless piston, as shown in Fig. 2.1. At the start, the gas occupies a volume of $1.8 \times 10^{-3}\,\text{m}^3$ at a pressure of $3.3 \times 10^{5}\,\text{Pa}$ and a temperature of $310\,\text{K}$.

At the start, a sample of an ideal gas is in state A, with pressure $2.0 \times 10^5\,\text{Pa}$ and volume $0.016\,\text{m}^3$, as shown in Fig. 3.1. In state A, the gas has temperature $400\,\text{K}$. The gas then goes through two changes in sequence, X and Y. For change X, the gas is heated at constant volume until the pressure becomes $4.0 \times 10^5\,\text{Pa}$. When X is complete, the gas is in state B. For change Y, it then expands at constant temperature until its original pressure is reached again. When Y is complete, the gas is in state C.
