What is the pressure at the surface of Mercury in N per m2?
If you're referring to atmospheric pressure, then it's zero.Mercury has no atmosphere.
When air pressure increases the liquid in a Mercury barometer what?
When air pressure increases, it exerts greater force on the surface of the mercury in the barometer. This additional pressure causes the mercury to rise higher in the glass tube, indicating a higher atmospheric pressure. Conversely, if the air pressure decreases, the mercury level falls. Thus, the height of the mercury column in the barometer is directly related to the atmospheric pressure.
In a mercury barometer when air pressure increases the mercury in the tube .?
In a mercury barometer, when air pressure increases, it exerts more force on the surface of the mercury in the reservoir, causing the mercury to rise within the tube. This rise occurs because the increased atmospheric pressure pushes down on the mercury, forcing it to ascend. Conversely, when air pressure decreases, the mercury level falls. The height of the mercury column is a direct measurement of atmospheric pressure.
A decrease in the height of a column in a mercury barometer means that .'s surface?
When air pressure increases, the mercury in a barometer rises.
What equals the force of Earth's atmosphere on the mercury in the dish?
The force of Earth's atmosphere on the mercury in the dish is equal to the atmospheric pressure acting on the surface area of the mercury. This can be calculated using the formula ( F = P \times A ), where ( F ) is the force, ( P ) is the atmospheric pressure (approximately 101,325 Pa at sea level), and ( A ) is the surface area of the mercury in the dish. The pressure exerted by the atmosphere pushes down on the mercury, causing it to rise in a connected column, such as in a barometer.
What is mercury's surface pressure?
It is negligible.
What kind of surface pressure is on mercury?
Mercury has a surface pressure that is near enough zero or a vacuum, since the planet holds no atmosphere due to its small size.
What is the pressure at the surface of Mercury in N per m2?
If you're referring to atmospheric pressure, then it's zero.Mercury has no atmosphere.
What does a mercury barometer measure and how does it work?
A mercury barometer measures atmospheric pressure, which is the weight of the air pressing down on Earth's surface. It works by using a column of mercury in a sealed tube to balance the pressure of the air outside. When the air pressure increases, the mercury in the tube rises, and when the air pressure decreases, the mercury falls.

This additional pressure causes the mercury to rise higher in the glass tube, indicating a higher atmospheric pressure. Conversely, if the air pressure decreases, the mercury level falls.

Which planet s air pressure is 30 km above the earths surface?
mercury
How heavy is air pressure near earth's surface?
About equal to 30 inches of Mercury.
Describe how a mersury barometer measures airpressure?
A mercury barometer is a 1 meter long glass tube with the top sealed and turned upside down in a bath of mercury the pressure on the surface of the bath of mercury lifts the level of the mercury in the tube dependent on atmospheric pressure.
What is planet mercury's surface pressures?
Planet Mercury's Surface pressure is almost none existent. This is due to its low gravity and extremely thin atmosphere that has been blasted away by solar winds.
What is the space above the mercury in the tube of a mercury barometer?
The space above the mercury in the tube of a mercury barometer is a vacuum, meaning it is devoid of air or any other gases. This vacuum allows for accurate measurement of atmospheric pressure, as the height of the mercury column is influenced solely by external air pressure acting on the surface of the mercury in the reservoir. Changes in atmospheric pressure will cause the mercury to rise or fall in the tube, providing a reliable indication of current pressure levels.
Why are mercury drops spherical?
Mercury has a very high surface tension and does not easily wet most other surfaces. For a given amount of mercury, a sphere has the smallest possible ratio of surface area to volume and is therefor the lowest energy shape for the mercury.
