1) Consider the system shown in the figure. When the pins fall away, the gas expands against a
constant external pressure to 1 atm. How much work was performed on the surroundings?
Calculate univ S for this irreversible process, and determine the additional work T S univ
that could have been extracted had the expansion to the same final pressure been carried
out reversibly. (Alternatively, think of a way to carry out a reversible expansion and calculate
the reversible work. The difference between the reversible work and the work you
calculated for the irreversible process above is the additional work.)
Number of moles of the gas, n=10
Initial pressure Pi= 5atm
External Pressure Pext = 1 atm
T = 300 K
