The speed at which hot air rises depends on various factors such as the temperature difference between the hot air and its surroundings, the density of the air, and any obstacles in its path. Typically, hot air rises at a rate of around 1-3 feet per second.
A tornado forms
in a pot on the stove, cold water sinks to the bottom and hot water circulates on the top of the pot. (The colder water needs to become hot, so it sinks to the bottom. That's why you see movement in the pot of water.)
An hot air balloon i think.
The hot air rising from the pavement on a hot summer day is an example of convection. As the ground heats up, it warms the air directly above it, causing it to rise and creating the shimmering effect that is visible.
Rising and sinking air is called up draft and down draft, respectively.
Rising hot air and water condensing out of that air.
it is a thermal current

Here are 2 examples: - hot airballoon - hot air rising, and cold air falling.
Yes. Hot air is less dense, and therefore lighter than cold air, so it will rise as cold air will drop. A perfect example of this, is smoking rising to the ceiling in a fire, or smoke rising out of your chimney.
hot air rising (less dense air), gravity. aero dynamics dont do much
As in other hot countries .

No, a hot air balloon rising is a physical change, not a chemical change. The balloon rises because the air inside it is heated, causing it to expand and become less dense than the surrounding air, which causes it to float upwards.
The word "convection" is often used in this context.
Velocity = Distance/Time for most all movement problems While the above formula is true for most movement problems, air speed is not a velocity. Air speed is speed of an aircraft relative to the surrounding air. The air speed of a hot air balloon is always zero because it is not moving through the air.
It's evaporation, or hot air rising!Da, stupid!
