What is mercury's surface pressure?
It is negligible.
What is the surface pressure on Mercury?
The atmospheric density on Mercury has not been directly measured, and may not be for many years. The thin collection of ionized gases on Mercury has an estimated surface pressure only ten-quadrillionths that of Earth (about 10-14 bar or 10-9 Pa).
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.
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.
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.
What kind of pressure does a column of air exert on the air or surface below it?
air 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.
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.
Why Mercury is used in spygmomanometer?
Mercury is a heavy, silvery-white metal.Due to the high density of mercury a rise in small column of mercury can exert much pressure. so it is used to measure pressure as a small tube is sufficient to measure a considerable pressure.More over Mercury does not stick to the glass surface inside
What kind of wind does a low pressure system have?
A low pressure system contains near surface winds.
What kind of geography does mercury have?
Mercury has a surface geography that is very much similar to our moon: it has craters, tall cliffs, and large flat plain areas.
