Problem 43

In Fig. 18-37, a gas sample expands from  to 4.0  while its pressure decreases from  to /4.0. If  = 1.0 m3 and  = 40 Pa, how much work is done by the gas if its pressure changes with volume via (a) path A, (b) path B, and (c) path C?

                                                              Step by Step Solution

Step 1 of 3

(a)  Path A:

The pressure is constant at 40Pa, the volume changes from 1 cubic meter to 4 cubic meter.

Work done is:

Hence the work done by the gas in path A is 120J.
