A Carnot engine uses the expansion and compression of n moles of argon gas, for which CV=(3/2)R. This engine operates between temperatures TC and TH. During the isothermal expansion a→b, the volume of the gas increases from Va to Vb=2Va.

a)Calculate the work done during the isothermal expansion a→b. Express your answer in terms of the variables n, TH, and gas constant R.

b)Calculate the work Wbc done during the adiabatic expansion b→c. Express your answer in terms of the variables n, TC, TH, and gas constant R.

c)For this engine, Wab=Wbc. Find the ratio TC/TH.

d)Find the efficiency of the engine.

7. 1.55 moles of Argon gas undergo an isothermal reversible expansion from an initial volume of 5.00 L to 105. L at 300 K. Calculate the work done during this process using: (a) the ideal gas equation, and (b) the van der Waals equation of state. Van der Waals parameters for Ar are available in the back of the book. Compare the two results, what percentage of the work done by the van der Waals gas arises due to having...

A heat engine composed of 1.6 moles of an ideal, monotonic gas is initially at 350 K and 1x10^5 Pa. The first step is an isothermal expansion to a pressure of 5x10^4 Pa. Second, the gas is compressed at constant pressure back to the inital volume. Finally the gas returns, at constant volume to the initial state. What is the total work done by the gas during this cycle? What is the efficiency of this cycle?

28 moles of an ideal gas with a molar specific heat at constant volume of cv=3.2R is initially in state "A" at pressure 73390 Pa and volume 1.0 m3. The gas then expands isobarically to state "B" which has volume 2.6?3m3. The gas then cools isochorically to state "C". The gas finally returns from state "C" to "A" via an isothermal process. What is the adiabatic constant γ for this gas? What is Q during the expansion from "A" to...
