It measure the Atmospheric Pressure.
A Mercury barometer is used to measure atmospheric pressure.
A barometer is used to measure air pressure. It measures the atmospheric pressure using air, mercury, or water and will be shown as inches of mercury or millibars.
One statement to accurately describe a difference between a mercury barometer and an aneroid barometer is that a mercury barometer is a closed tube containing mercury. An aneroid barometer is a closed, flexible container of gas.
A barometer that uses mercury measures air pressure by monitoring the height of the mercury column in a tube. As air pressure changes, the mercury level rises or lowers in response. This instrument is called a mercury barometer.
The device used to measure air pressure is called a barometer. It can be either an aneroid barometer or a mercury barometer, both of which are commonly used to measure atmospheric pressure.
Torricelli invented a device for measuring air pressure called a mercury barometer. It consists of a glass tube filled with mercury placed in a dish of mercury. The height of the mercury in the tube changes with variations in atmospheric pressure.
The two common types of barometers are mercury barometers, which use the height of mercury in a column to measure atmospheric pressure, and aneroid barometers, which utilize a flexible metal membrane to detect and measure pressure changes without using liquid. Digital barometers are also becoming more popular, using electronic sensors to measure pressure.
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
a barometer... and it is invented by torricelli..
Mercury barometer is used for measuring atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.
A mercury barometer.
An aneroid barometer measures air pressure using a flexible metal box called an aneroid cell, whereas a mercury barometer uses a column of mercury to measure air pressure. Aneroid barometers are more portable and do not use toxic mercury like mercury barometers.
