A tube contains enclosed air by a thread of mercury of 250 mm long when tube is horizontal the length of air is 250 mm long what is the pressure on the air column when atmospheric pressure is 750 mmhg?
A tube contains enclosed air by a thread of mercury of 250mm long when tube is horizontal the length of air is 250 mm long. The pressure on the air column when atmospheric pressure is 750 mm Hg is 3 Pascal or 3 N / m2.
What prevents mercury in the tube of a barometer from running out into the container at the bottom of the tube?
The top of a barometric tube is sealed leaving no place for air to escape. It works along the same principle as a drinking straw, but in reverse. In a drinking straw, the sucking motion reduces the pressure of the air inside the straw to a lower level than the air outside the straw. Liquid resists changes in volume due to pressure and is drawn up through the tube due to the air pressure exerted on the surface of the liquid outside the straw. In a barometric tube the tube is sealed at one end, trapping a finite amount of gas in the tube. The air pressure inside and outside the tube is equal, keeping the mercury suspended at a certain level. If the pressure outside is raised, more force is exerted on the surface of the mercury outside the tube than on the surface inside. This raises the level of the mercury in the tube until the pressure of the air is equalized -- there is still just as much air in the tube, but a smaller volume at a greater pressure.
