A fire makes things hot. Above a fire, you get quite a lot of hot air. Hot air is less dense than cool
air, so it rises. Because there is quite a lot of hot air, it makes quite a big wind current as it rises,
and that drags the smoke particles upward with the air, in much the same way as wind can raise
dust. Some of the smoke particles are very small indeed, so they can be held up in the air for quite
a long time, and they do not settle out from the air until a long time after they leave the fire, and
usually some distance away from the fire.
In a large bushfire, all the hot air produced makes very strong currents indeed, and not only fine
particles, but also quite large burning twigs and leaves can be carried up in the smoke, and do not
fall out until they have travelled quite some distance. It is these pieces of burning vegetation --
called "embers" -- that often start secondary fires, and make fighting large bushfires extremely
difficult and dangerous.

Which kind of heat transfer causes smoke to rise from a fire?
Convection is the heat transfer process responsible for causing smoke to rise from a fire. As air near the fire gets heated, it becomes less dense and rises, carrying the smoke along with it.
When petrol is set a light is there any smoke?
yes because ever thing may blow up and smoke will rise off the fire
Does cigarette smoke rise or fall in a closed room?
Cigarette smoke rises in a closed room because it is lighter than the surrounding air.
Why does smoke from burning materials rise in the air?
Smoke rises in the air due to the difference in temperature between the smoke and the surrounding air. When materials are burned, the heat causes the air inside the smoke to expand, making it less dense and causing it to rise. This process creates air currents that carry the smoke upwards.
Does smoke from fire rise or raise in the air?

Why does smoke from a cigar rise and then settle off?
because it vibrates into the air and becomes oxegin
Does cigarette smoke travel up or down in a closed room?
In a closed room, cigarette smoke tends to rise upwards due to its heat and buoyancy.

Does smoke travel up or down in a closed room?
Smoke typically travels upwards in a closed room due to the natural tendency of hot air to rise.
When coal burns particles of soot rise up above the fire and make smoke. why doesn't the smoke move along the ground?
Smoke rises instead of moving along the ground primarily due to its temperature and density. When coal burns, it generates heat, causing the smoke to become less dense than the cooler air around it. This difference in density creates an upward buoyant force, causing the smoke to rise. Additionally, air currents can further facilitate the upward movement of smoke particles.
