(6)A liquid partially fills a container. Explain why the temperature of the liquid decreases if the container is then partially evacuated. (Using this technique, it is possible to freeze water at temperatures above 0ºC.) (7) A gas is compressed at a constant temperature. What happens to the mean free path of the molecules in this process? If a helium-filled balloon initially at room temperature is placed in a freezer, will its volume increase, decrease, or remain the same?
