What does this mean in maths mm Hg?
The term mm Hg means millimeters of mercury; this is a measurement of barometric pressure (the pressure of air is measured in terms of the equivalent height of a column of mercury that would exert the same pressure). 1 mmHg is about 133 pascals.
What a barometer with Mercury?
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
Can compressed air exert pressure on things?
nimple
What is mercury air pressure compared to earth?
Mercury has no atmosphere, hence it has no air pressure at all.
Who invented the Mercury baromenter?
The mercury barometer was invented by Italian scientist Evangelista Torricelli in 1643. He created this device to measure atmospheric pressure, demonstrating that air has weight and can exert pressure. Torricelli's invention laid the groundwork for modern meteorology and our understanding of weather patterns.
What happens if air does not exert pressure?
Depends on how you do that - but most are fatal.
An increase in air pressure will cause the mercury in a barometer to?
When you increase air pressure the mercury in a barometer will rise. Conversely when air pressure decreases the mercury in a barometer will drop.
Dose air in the atmosphere exert pressure on earths surface?
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
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.
Why do fluid create pressure?
Fluids have a higher density than air and therefore exert more pressure than air.
Why does water exert more pressure than air?
Water is more dense than air is.
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.
