Why does soot particles rise above the fire and make smoke?
Soot particles are lighter than air and rise due to convection currents created by the heat of the fire. As the soot rises, it cools and mixes with air, forming smoke. The smoke is a combination of the soot particles and other gases and particles produced by the combustion process.
A story that link there is no smoke without fire?
There is a saying that where there is smoke, there is fire. This means that if there is evidence of something happening, then it is likely that there is a fire, or cause, for it. This saying can be applied to many situations in life. For example, if there is smoke coming from a building, it is likely that there is a fire inside. If there is smoke coming from a car, it is likely that the engine is on fire. In both of these cases, the smoke is evidence of a fire, or cause.
Why does The smoke from a bonfire rises upwards?
The smoke from a bonfire rises upwards due to the difference in temperature between the smoke and the surrounding air. As the hot smoke rises, it mixes with the cooler surrounding air, creating vertical movement. Additionally, the heat from the fire creates a convection current that helps propel the smoke upwards.
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.
What is the difference between a smoke door and fire door?
A smoke door is designed to prevent the spread of smoke during a fire, while a fire door is designed to resist fire and prevent its spread for a specified period of time. Fire doors are typically rated for a specific amount of time (e.g. 60 minutes), whereas smoke doors are designed to limit smoke transmission without a fire rating.
What is it called when hot smoke gases up and go to the chimmeny?
This process is called "flue gas exhaust," where hot smoke gases from a fire or combustion process are directed up a chimney or flue to be released into the atmosphere.
What are the main features of a wild fire?

Why smoke goes up?
My guess is that it's because smoke is hot. Hot air rises, just as cold air sinks. When a fire ensues, smoke (the product of carbon combustion) rises with the hot air.
How does a smoke alarm work?
press onThere are two kinds of smoke detectors. 1. When a fire burns, it releases smoke. The smoke detector senses the smoke. 2. A fire is very hot. The detector feels the heat. A smoke detector will then either set off an alarm, or it will turn on the sprinklers.

What is smokeless fire?
No one knows because smoke doesn't have to be visible to exist. Smoke and heat is a combination of hot air and the smoke depends on the material being burned, some burn light and others dark black smoke. Does burning gas from a lighter have no smoke?well, it still burns and heats the air around it and it climbs fast vertically and blurs the air.. That is invisible smoke or hot air from a clean burning fuel. That brings us to one conclusion, smokeless fire is a fire that gives no heat and that is not something of this realm. however, the Muslims have a description of demons in the Qur'an as been created from "smokeless fire" and humans from clay.
