How is the can in the pan of water similar to the mercury barometer?
Both the can in the pan of water and the mercury barometer function based on the principle of atmospheric pressure. In both cases, changes in atmospheric pressure will cause a corresponding change in the level of water or mercury in the device. The height of the water or mercury serves as an indicator of the atmospheric pressure at that moment.
What pushes Mercury up in a tube of a Mercury barometer?
That depends on the 'tube' involved. In a thermometer the mercury expands and contracts within a sealed tube as the temperature is raised or lowered. In a barometer there is a reservoir of mercury which the atmosphere presses on. This maintains the mercury in a column which is sealed at the top. Increases in atmospheric pressure push the mercury further up the tube, decreases let it drop down the tube.
How a Mercury barometer functions?
A Mercury barometer functions by measuring atmospheric pressure using a column of mercury in a glass tube. The tube is inverted into a reservoir of mercury, and as atmospheric pressure changes, it either pushes the mercury up or allows it to fall within the tube. The height of the mercury column, typically measured in millimeters or inches, corresponds to the atmospheric pressure, with higher columns indicating greater pressure. This device effectively translates pressure variations into measurable height differences of the mercury.
What is mmHg on a barometer?
mmHg stands for millimeters of mercury and is a unit of pressure commonly used in barometers to measure atmospheric pressure. It represents the height of a column of mercury that the atmospheric pressure can support.
Expressed in mm of mercury?
Pressure, in particular atmospheric pressure.
If the atmospheric pressure is 29.4 inches of mercury what is the corresponding pressure of mercury?
The atmospheric pressure of 29.4 inches of mercury is equivalent to 74.676 millimeters of mercury. This conversion is based on the standard ratio where 1 inch of mercury is equal to 25.4 millimeters of mercury.
What are the uses of a Mercury barometer?
A Mercury barometer is used to measure atmospheric pressure.
What are mercury's atmospheric gases?
Hydrogen, Helium

What does Mercury borometer measure?
A mercury barometer measures atmospheric pressure by determining the height of a column of mercury that is supported by atmospheric pressure in a closed tube. By observing changes in this column height, meteorologists can track changes in atmospheric pressure over time.

What do mercury barometer measure?
It measure the Atmospheric Pressure.
What the perssure on the planet mercury?
The atmospheric pressure is negligible.
When air pressure decreases the mercury in a barometer?
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
