Question
1.00×10^(−3) moles of ideal monotonic gas expands from a volume of 2.00 cm^3 to 4.00 cm^3 at a starting temperature of 30 ◦C. For this gas γ = 1.67. Draw the pressure-volume diagram for the case that the expansion is isothermal. Ensure that you include numerical results for the pressure at the end points of the process. On the same graph, add the pressure-volume curve for the case that the expansion is adiabatic. What is the temperature of the gas after the adiabatic expansion?

- Problem 4: Consider a cylinder with a movable piston containing n moles of an ideal gas. The entire apparatus is immersed in a constant temperature bath of temperature T Kelvin. The piston pushes slowly outward on an external body which matches the force momentarily at each instant so that the gas expands quasi-statically from a volume V1 to V2 at constant temperature T. The isothermal process is shown in the figure above, where the pressure p is related to the volume V by the ideal gas law as follows: pV = nRT, where R is the gas constant. Part (b) For n = 3 moles, T = 350 K, and V2 = 2.5V1, determine the work done by the gas on the external body.
