A bottle at 285 K contains an ideal gas at a pressure of 155.7 x 103 Pa. The rubber stopper closing the bottle is removed. The gas expands adiabatically against Pexternal = 111.4 x 103 Pa, and some gas is expelled from the bottle in the process. When P=Pexternal, the stopper is quickly replaced. The gas remaining in the bottle slowly warms up to 285 K. What is the final pressure in the bottle for a monatomic gas, for which CV = 3R/2, and for a diatomic gas, for which CV = 5R/2?
