What is a mercury barometer?
A mercury barometer is a device that measures air pressure. The key component that distinguishes it from other barometers is the metal mercury.
Who invented a the bareometer?
The first barometer was devised in 1643 by Evangelista Torricelli. Torricelli had set out to create an instrument to measure the weight of air, or air pressure, and to study the nature of vacuums. He used mercury, perhaps on a suggestion from Galileo Galilei, because it is significantly denser than water. To create a vacuum with water takes a column over 30 feet long, while with mercury it takes less than four feet.
Named after inventor Evangelista Torricelli the torr is a unit of measure for what property?
The torr is a unit of measure for pressure. It is defined as the pressure exerted by a column of mercury that is 1 millimeter in height, under standard gravity. It is commonly used in scientific and engineering applications to measure low pressures.
