Part (a)  For n = 1 moles, T = 305 K, and V2 = 3.5V1, determine the work done by the gas on the external body. The gas constant is R = 8.314 J K-1 mol-1

W = ______

Problem 3: 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.
