When air pressure goes up the liquid in a mercury barometer goes?
When air pressure goes up, the liquid in a mercury barometer goes down. This is because as air pressure increases, it pushes the mercury in the tube to rise, indicating higher pressure.
Which instrument measures the air pressure using a metal chamber from which some air has been removed?
A barometer measures air pressure using a metal chamber from which some air has been removed. The most common type is the mercury barometer, where the air pressure pushes down on a pool of mercury in a glass tube to indicate atmospheric pressure.
How do differences in air pressure help smoke to rise up a chimney?
Differences in air pressure create a pressure gradient that causes air to move from high pressure areas to low pressure areas. When the air inside the chimney is heated by the fire, it becomes less dense and rises. This creates a lower pressure inside the chimney relative to the outside air, which causes the smoke to be drawn up and out of the chimney.
Why does wind flow from areas of high pressure to those of low pressure?
Wind flows from areas of high pressure to low pressure due to the pressure gradient force, which is a result of differences in air pressure. Air always moves from high to low pressure to try to equalize the pressure across a region, creating wind in the process.
What happens when a warmer air mass pushes a cooler air mass?
When a warmer air mass pushes a cooler air mass, it creates a boundary known as a frontal boundary. This can lead to the cooler air being lifted and condensed, resulting in the formation of clouds and potentially precipitation. The interaction between the two air masses can also lead to changes in temperature, humidity, and pressure in the region.
How does air pressure affect air movement?
Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.
Does air only push down on you?
no it does not it pushes down on every thing even rocks
When air expands and pushes it is called?
barometric pressure
What do diaphagm do in your body?
It pushes air into your lungs
Why when you suck a air of a bottle it shrinks?
When you suck air out of a bottle, you decrease the air pressure inside the bottle. The higher air pressure outside the bottle then pushes the walls of the bottle inwards, causing it to shrink. This is due to the difference in air pressure inside and outside the bottle.
Why is the air pressure greatest at the serface?
The air pressure is greatest at the surface because the weight of the air above pushes down on the air below, compressing it and creating higher pressure. As you move higher in the atmosphere, there is less air above exerting pressure, so the air pressure decreases.
How does water get into an air pressure tank?
If you mean a well tank, the water is forced in by the pump. The residual air pressure pushes the water out to the faucets.
What is the work of the diaphragm in the body?
It helps the air to be taken in & pushes into the lungs
What effect does pressure have on a bottle rocket?
it pushes the rocket into the air to make it go higher.
Why is the air pressure higher when you get closer to the ground?
Air pressure increases with decreasing altitude because the weight of the air above pushes down on the air below, compressing it. This compression causes the air molecules to be closer together, increasing the pressure.
How does pressure cause air to move?
Pressure cause air to move because all the weight pushes up or down and causes it to go the opposite direction.
In which direction is the air pressure exerted?
Air pressure is exerted in all directions equally. This means it pushes in every direction - up, down, sideways, and diagonally.
