There is a small amount of water at the bottom of a sealed containerof volume 4.3 liters which is otherwise full of an ideal gas. A thin tube open to the atmosphere extends down into the water, and up to a height of 238 cm. The system is initially a pressure that maintains a column of water that just reaches the top of the tube, and at temperature 149 Celsius.
If we increase the temperature of the gas until .67 liters of water have exited at the top of the tube, then what is the temperature?
