Question

uses of mercury barometer

Answer 1

Mercury barometers are principally utilized for measuring barometrical weight. It is a gadget that comprises of a topsy-turvy tube loaded with mercury that is in a vessel brimming with mercury. The climate (or the air) pushes down on the mercury in the vessel, which thus, drives the mercury in the tube up. Furthermore, the stature of mercury in this tube (otherwise called the tallness of mercury segment) is utilized as a measure of air pressure.

For example, 1 air pressure causes a stature of 760 mm of mercury in the tube and consequently, 1 air pressure is likewise proportionate to 760 mm or 76 cm of mercury head.
