3 0 Moles Of An Ideal Gas Are Subjected To The Following Processes First The Volume Is Tripled In An Isobaric Process 1 (241.74 KiB) Viewed 37 times

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 2.0 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 (vertex) with a letter (A, B, ...) and each transition with a number and arrow showing the direction of the process. (b) If the isothermal process occurs at a temperature of 900 K, what is the pressure, tempera- ture, and volume for each state. (c) Find the work done on the gas, the heat in and out of the gas, and the change in thermal energy for each of the processes.
