What else can I help you with?
Expressed in mm of mercury?
Pressure, in particular atmospheric pressure.
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.
To measure pressure above atmospheric pressure you would use a?
mercury manometer
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.
What does the pressure units 30.03 in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of mercury on a mercury barometer
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 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.
Expressed in mm of mercury?
Pressure, in particular atmospheric pressure.
When air pressure decreases the mercury in a barometer?
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
What are the uses of a Mercury barometer?
A Mercury barometer is used to measure atmospheric pressure.
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 do mercury barometer measure?
It measure the Atmospheric Pressure.
What the perssure on the planet mercury?
The atmospheric pressure is negligible.
What does the pressure units in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of Mercury on a mercury barometer
To measure pressure above atmospheric pressure you would use a?
mercury manometer
Why do Mercury and Mars have no atmospheres?
Their gravity is too weak to hold on to atmospheric gases.
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.
