How do differences in air pressure help smoke to rise up a chimney?
the higer pressure at the bottom of the chimney pushes air and smoke up the chimney
Why is air pressure at the top of a chimney less than air pressure at the bottom?
Smoke rises up the chimney partly because hot air rises and partly because it is pushed wind blowing across the top of a chimney lowers the air pressure there the higher pressure at the bottom pushes air and smoke up the chimney
What is a low pressure trough?
When air pushes through the ground and makes clouds form, well, something like that anyway.
When cold air moves toward warm air it pushes the warm air where?
It pushes the warm air above the cold air
Is high pressure warm front or cold front?
warm front is low pressure , cold front high pressure . because it pushes down on the surface (because cold air sinks) it makes high pressure .
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.
How is drinking from a straw the same as an egg going into a glass bottle?
Drinking from a straw is the same as an egg going into a glass bottle, because air pressure in both cases is used to move something. In the straw, you reduce the air pressure in the straw, so the air pressure around the drink pushes it up into the straw and into your mouth. In the egg, you reduce the air pressure in the bottle, and air pressure around the egg pushes it down into the bottle.
When air expands and pushes it is called?
barometric pressure
Why do balloons come closer when air is blown between them?
The wind between the balloons creates a lower pressure in the air, so the air around it pushes the balloons together.
What do diaphagm do in your body?
It pushes air into your lungs
How is air pressure used in a vacuum cleaner?
air presure pushes dirt into the vacuum cleaner.
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.
How do differences in air pressure help smoke to rise up a chimney?
the higer pressure at the bottom of the chimney pushes air and smoke up the chimney
When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
What is a vacuum in science?
somewhere where there is absolutely nothing- no air, no atoms of any sort. You can get radiation such as light in vacuums though. If you are in a vaccum as there is no air pressure your lungs go inside out and you get sucked to pieces, well actually your body's internal air pressure pushes you apart but it's the same thing
What makes you fart when you cough?
When you cough, it can create pressure in your abdominal area which can push air out and cause you to fart. This is because the same muscle groups are involved in coughing and passing gas. Additionally, swallowing air while coughing can also contribute to farting.
What effect does pressure have on a bottle rocket?
it pushes the rocket into the air to make it go higher.
