Gases have been observed to satisfy the relationship pvn = c, where n and c are constants, during some actual expansion and compression processes in piston-cylinder devices. calculate the work done in kj when a gas expands from 147.4 kpa and 1.76 m3 to a final volume of 2.38 m3 for the case of n = 1.46.

a. 55.89
b. 60.12
c. 62.40
d. 65.00
