Question

Steps: (a) an isobaric expansion to a volume of 10.0 L, (b) an isochoric change to a pressure of 0.50 atm, (c) an isobaric compression to a volume of 4.0 L, and (d) an isochoric change to a pressure of 2.0 atm.

Show these steps on a PV diagram drawn in your notebook and determine from your graph the net work done, Wgas by the gas.
Use 1 atm ≈ 105 Pa and 1L = 10-3 m³.
Wgas _________

Answer 1

To show the steps on a pV diagram, plot the points corresponding to each step. Net work done by the gas can be determined by calculating the area enclosed by the steps on the pV diagram.

Step-by-step explanation:

To show the steps on a pV diagram, we need to plot the points corresponding to each step. For step (a), the pressure remains constant at the initial pressure, and the volume increases to 10.0 L. This results in a horizontal line on the pV diagram. For step (b), the volume remains constant, so there is no change in the volume on the diagram. The pressure decreases to 0.50 atm, resulting in a vertical line. Step (c) is similar to step (a), but the volume decreases to 4.0 L, resulting in another horizontal line. Finally, step (d) is the same as step (b), but the pressure increases to 2.0 atm, resulting in another vertical line.

The net work done by the gas can be determined by calculating the area enclosed by the four steps on the pV diagram. However, since we do not have the specific shape of the steps, we cannot accurately calculate the net work. We need more information to determine the shape and size of each step.
