Chapter 18, Problem 16E
An ideal gas expands from the state (p1, V1) to the state (p2, V2), where p2 = 2p1 and V2 = 2V1. The expansion proceeds along the diagonal path AB in Fig. 18.19. Find an expression for the work done by the gas during this process.

During real expansion and compression processes in piston cylinder devices, it has been observed that gases satisfy the relationship PVn = C, where n and C are constant. Calculate the work done when a gas expands from 350 kPa and 0.03 m3, to a final volume of 0.2 m3, for the case where n = 1.5.
The formula for work in thermodynamics is given by PV=W. Suppose that at any pressure, P=h(V+Vo-1) where V is the volume and Vo is the initial volume. h and Vo are constants. If work is to be maximized, what is the correct expression of maximum work in terms of constants?
