3 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 kPa.The volume is then halved in another isobaric process. Finally, it returns to the original state in an isochoric process.
(a) Draw a PV diagram of the cycle. Label each state with a letter (A, B, …). For the transitions, number them with the corresponding number and arrows showing the direction of the process.
(b) If the isothermal process occurs at a temperature of 900 K, what is the pressure, temperature, and volume for each state?
(c) For each of the processes:
Find the work done on the gas.
Find the heat in and out of the gas.
Find the change in thermal energy.
(d) Find the total work, exchanged heat, and the change in thermal energy.
