Smoke rises up a chimney partly because of what principle?
Bernoulli's Principle
In which direction does heat move?
up because heat rises
Why does fire always point up?
Heat rises to colder areas.
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.
Why does smoke rise up a chimney?
Hot air rises, just as cold air lays low (sinks) to the ground. When a fire ensues, smoke (the product of carbon combustion) rises with the hot air. Chimney design is what keeps smoke from just going anywhere around a fireplace. A chimney uses the principles of rising hot air and acts as funnel. A chimney's flue (the device which controls the amount of air drawn up the chimney) affects the funnel effect dramatically. As hot air rises up the chimney, the fire consumes more oxygen in the room where the fireplace is, creating a vacuum effect, which in turn feeds the flame with even more oxygen faster. It is the combination hot air rising and subsequent vacuum effect in the room below which ensures that smoke from a fireplace fire will go up a chimney. ithout the control of the chimney flue, this effect could quickly lead to a fireplace fire getting too hot for the fireplace to handle. This effect can also be extremely dangerous in a house fire or a building fire in which there are drop ceilings. Some natural building areas, such as stairwells, act as natural chimneys. In office buildings with drop ceilings, it is against fire codes to have any drop ceiling tiles removed, as this can cause a chimney effect if a fire were to break out. Remember since a chimney effect leads to oxygen been fed to a fire at faster rates, the fire can quickly accelerate and consume an area.

Bernoulli's Principle
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

Heat given off by fire in a fireplace is an example of what?
Heat cast forward out of a firepalce is called radiant heat and it the only usable heat that a fireplace can create The wasted heat that a fireplace creates is called combusion heat that rises up the chimney.
In which direction does heat move?
up because heat rises
Which direction does heat move?
up because heat rises
What direction does heat travel in?
Heat travels from Hot to cold. Not up!
How does a hot air balloon go up and down?
Heat rises of it makes the ballon rises
How do you make a sentence making the word flue?
At the beginning of fall, before you build a fire in your fireplace make sure to open the chimney's flue.
Why fire always points up?
Heat rises and so pushes them up.
Why do the cornish tin mine chimney stacks have brick at the top half and not stone like the rest of the construction?
The top of the chimney was made from brick because this would heat up faster than stone, and if the top of the chimney is hotter than the rest of the chimney then the draught of air rising up the chimney would increase, therefore making the chimney more efficient.
