Question
A barometer has air trapped above the mercury in an inverted tube with the opening in a reservoir of mercury.
When the length l of air trapped is 10.0cm, the mercury height h is 72.0. When the tube is slightly lowered into the reservoir, l becomes 8.0cm. What is the new h?
Take atmospheric pressure to be equivalent to 76.0cm mercury.
