The Galileo barometer, invented by the Italian physicist and astronomer Galileo Galilei round 1643, is a straightforward but efficient machine for measuring atmospheric strain. It consists of a glass tube, sealed at one finish, and crammed with a liquid, usually water or mercury. The open finish of the tube is positioned in a reservoir of the identical liquid, and the peak of the liquid within the tube is noticed.
The peak of the liquid within the tube is inversely proportional to the atmospheric strain. It’s because the load of the liquid within the tube is balanced by the power exerted by the ambiance on the floor of the liquid within the reservoir. When the atmospheric strain will increase, the power exerted on the liquid within the reservoir will increase, which causes the liquid within the tube to rise. Conversely, when the atmospheric strain decreases, the power exerted on the liquid within the reservoir decreases, which causes the liquid within the tube to fall.
