Ideal gas is confined to a volume of Vi within a piston-cylinder assembly at a pressure of pi . The piston-cylinder assembly is well-insulated. The gas is allowed to expand to a volume Vf in two ways: (1) reversibly, and (2) suddenly and irreversiibly. The pressure at the final state in both cases is larger than the pressure in the surroundings, p0. Answer the following questions:
a. Find the work done in the reversible process and irreversible/sudden process
b. Find the pressure at the final state in the two processes described here.
c. Show that the pressure at the end of the reversible process is always less than the pressure at the end of the irreversible process.
