Differences in air pressure cause air to flow from areas of high pressure to low pressure. In a chimney, the warm air from the fire creates a lower pressure inside the chimney relative to the outside, causing the smoke to rise up and out of the chimney.

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.


How does smoke move in the chimney?

Smoke moves in the chimney due to the difference in temperature and pressure between the inside and outside of the chimney. As hot air rises, it creates a draft that draws the smoke up and out of the chimney. The design of the chimney, including its height and width, can also impact how efficiently the smoke is expelled.


Why is the air pressure at the top of the chimney less than the 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

Explain this phenomena when a fireplace smoke rises up the chimney faster when wind is blowing outside?

Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.


Tree is to shade as chimney is to what?

Smoke. A chimney releases smoke just as a tree provides shade.

Why is smoke going in the house and not up the chimney?

A chimney will suck air from the house only if there is wind above the chimney. Air movement at the top causes a partial vacuum in the chimney which pulls the smoke up. The smoke could get into the house due to several reasons: there is no wind above the chimney; the chimney is blocked, the smoke is being directed away from the chimney due to other areas of low pressure in the house. You could probably rectify the problem by raising the chimney so that it catches more wind, cooking closer to the chimney inlet, making chimney diameter wider so that there is less resistance to the passage of smoke.

Why does smoke cause an egg to go into a bottle?

I don't think smoke would cause that. It is not clear what exactly the experimental setup is, but it is much more likely that the egg gets into the bottle through pressure differences.


Why does smoke blow into house and not out of chimney?

Smoke blowing into a house instead of out of the chimney can be due to improper ventilation or draft issues. This can be caused by a cold chimney, air pressure differentials, or obstructions like debris or animal nests blocking the chimney. It is important to address these issues promptly to prevent smoke from entering the living space.


A passage for smoke chimney?

shouldn't your question be," A passage for smoke in a chimney"? just saying


A loose vent connection at the chimney can cause?

smoke can reverse meaning the smoke( if you are very unlucky) can get in your house . and soms other stuff .
