Chapter 18, Problem 20E
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.

In an adiabatic process, oxygen gas in a container is compressed along a path that can be described by the following pressure in atm as a function of volume V, with V0 = 1L : p = (3.0 atm)(V/V0 )−1.2 . The initial and finalvolumes during the process were 2 L and 1.5 L, respectively. Find the amount of work done on the gas.
During some actual expansion and compression processes in piston–cylinder devices, the gases have been observed to satisfy the relationship PV n = C, where n and C are constants. 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 of n = 1.5.
2.00 kg of water has a volume of 2.00 x 10-3m3 when in the liquid state at 100 °C. When the water is completely changed from liquid to vapour at 100 °C, under a constant atmospheric pressure of1.01 x 105 Pa, the volume increases to 3.38 m3.
(i) How much work is done against the atmosphere as the water changes into vapour?(ii) What is the change in the internal energy of the water during vaporization?
