Mercury is poured into the open end of a J-shaped glass tube, which is closed at the short end, trapping air in that end. How much mercury can be poured in before the mercury overflows?
Assume air to act like an ideal gas. The long and short arms are 1m and 0.5 m long, respectively, and effects due to the curvature of the bottom may be neglected. Take atmospheric pressure to be 76 cm Hg.
The total pressure of the mixture is. 650 mmHg. What are the partial pressure of each of the gases ? He, and Xe
