A cylinder with a piston contains 0.250 mol of ideal oxygen at a pressure of 2.25x105 Pa and a temperature of 355K. The gas first expands isobraically to three time sits original volume. It is then compressed isothermally back to its original volume, and finally it is cooled isochrically to its original pressure.
1) Show the series of processes on a PV diagram.
2) Calculate the temperature during the isothermal compression.
3) Calculate the maximum pressure.
4) Calculate the total work done by the piston on the gas through the series of processes.
5) How much heat was transferred in or out of the piston through the series of processes?
