A cylinder with a piston contains ½ mole of an ideal gas initially at pressure 4.0 x105 Pa and temperature 300K. The gas then undergoes the following three processes, in order: a. expands at contant pressure to twice its original volume b. then is compressed isothermally back to its original volume c. then is cooled at constant volume to its original pressure. Compute the maximum pressure?
