A 0.400 mol sample of an ideal gas expands isothermally from T = 300 K and V = 1.00 L to V = 3.00 L.
a) How much work does the gas do if the expansion is into an evacuated space (vacuum)?
b) How much work does the gas do if the expansion is done against an external pressure of 3.00 atm?
c) What is the maximum possible work done by the gas?
d) Draw a P-V sketch to illustrate parts a, b, and c in a similar fashion to Figs. 19.2 – 19.4 of the textbook
