An ideal gas undergoes a single-stage expansion against a constant external pressure at constant temperature from

a. What is the largest mass m that can be lifted through the height h in this expansion?

b. The system is restored to its initial state in a single-state compression. What is the smallest mass m' that must fall through the height h to restore the system to its initial state?

c. If h = 10.0 cm, , T = 300. K, and n = 1.50 mol, calculate the values of the masses in parts (a) and (b).
