3.0 moles of an ideal gas are subjected to the following processes. First the volume is tripled in an isobaric process. Then it undergoes an isothermal process to a pressure of 9.0 kPa. The volume is then cut in half in another isobaric process after being tripled. Finally, it returns to the original state in an isochoric process. (a) Draw a PV diagram of the cycle. Label each state (vertex) with a letter (A, B, …) and each transition with...
