Work in the pV Plane The diagram shows the pressure and volume of an ideal gas during one cycle of an engine. (Figure 1)As the gas proceeds from state 1 to state 2, it is heated at constant pressure. It is then cooled at constant volume, until it reaches state 3. The gas is then cooled at constant pressure to state 4. Finally, the gas is heated at constant volume until it returns to state 1.

Step 1
According to the description, the gas is heated at constant pressure. This means that the work done on the gas during this process can be calculated by the area under the process curve on the pV diagram. Show more…

Work and Heat in PV Diagram Example 13: First law in isobaric and isovolumetric processes. An ideal gas is slowly compressed at a constant pressure of 2.0 atm from 10.0 L to 2.0 L. (In this process, some heat flows out of the gas and the temperature drops.) Heat is then added to the gas, holding the volume constant, and the pressure and temperature are allowed to rise (line DA) until the temperature reaches its original value (TA = TB). Calculate (a) the total work done by the gas in the process BDA, and (b) the total heat flow into the gas.

A monatomic ideal gas has pressure p1 and temperature T1. It is contained in a cylinder of volume V1 with a movable piston, so that it can do work on the outside world. Consider the following three-step transformation of the gas: The gas is heated at constant volume until the pressure reaches Ap1 (where A>1). The gas is then expanded at constant temperature until the pressure returns to p1. The gas is then cooled at constant pressure until the volume has returned to V1. It may be helpful to sketch this process on the pV plane. How much work W2 is done by the gas during step 2? Express the work done in terms of p1, V1, and A
