INDIVIDUAL SUMMARY: REVIEW OF THERMODYNAMICS I. One mole of an ideal gas, initially at 300 p
K, initially is cooled at constant volume so that the ﬁnal pressure is one—fourth the initial pressure. The gas then expands at constant pressure until it reaches the initial 9 /.

isothermally until it is at its initial volume and pressure. All the steps are quasi-static and reversible. L \
