♦ Relevant knowledge
Mercury column that is contained in the form of a U shape glass tube could be used to determine the pressure inside a container and compare it to the pressure in the atmosphere. The one end of the tube filled with mercury is an attachment to the container inside which the pressure is been measured, while the other end is left open to the air. If the mercury levels in both arms of the U tube is equal, then and the volume of the sealed container is the same as atmospheric pressure. When the length of the column in the closed container is greater in the arm that is free in U tube than in the free arm of tube than in the free arm of the tube which is open to air and the pressure inside the container that is closed is greater than atmospheric pressure by an amount that is equal to the difference in height of the mercury column in millimeters times the the mercury column.This is represented as millimeters Hg.
