A barometer is kept inside a bell jar. Air is slowly pumped out of the jar. (1) The mercury level starts rising (2) The mercury level starts falling (3) The mercury level does not change (4) The bell jar breaks up

Description : A barometer is kept inside a bell jar. Air is slowly pumped out of the jar. (1) The mercury level starts rising (2) The mercury level starts falling (3) The mercury level does not change (4) The bell jar breaks up

Last Answer : (1) The mercury level starts rising Explanation: As the pump removes the air from the bell jar the pressure obviously reduces around the barometer. The reduction in pressure around the barometer leads it to expand. As the pump removes air from the jar, the mercury level rises.
