Which one of the following statements is true? (a) The path on a PV diagram always goes from the smaller volume to the larger volume. (b) The path on a PV diagram always goes from the smaller pressure to the larger pressure. (c) The area under the path on a PV diagram is always equal to the work done on a gas. (d) The area under the path on a PV diagram is always equal in magnitude to the work done on a gas.

(a)

To determine

To say True or False: The path on a PV diagram always goes from the smaller volume to the larger volume.

Explanation

The curve on PV diagram is called the path taken between the initial states to the final state, with the arrow indicating the direction with the on-going process.
