when you heat matter, it expands. When you cool matter, it shrinks. So if you have hot air in a larger body of cool air (lets say a hot air balloon in the sky) it will weight less than the surrounding body of cool air, since its less dense (because the air is hot, thus expanded). This creates buoyancy which lifts the hot air, and this case, the entire balloon.
A cool thing about sulfur is that when you heat it up to it's melting point ( around 112 degrees Celsius) it turns to a kind of red liquid and creates a cool blue flame is set on fire. It also creates the gases Hydrogen sulfide and Carbon disulfide and sometimes even sulfur trioxide which is a very toxic gas. These three gases smell very terrible.
The process of warm air rising and cool air sinking is called convection current The process of warm air rising and cool air sinking is called convection current
Cool air rushes in to replace the rising warm air.

No. Mint does not cool down water. It only creates the senation of something being cool.
All they do is justflap them at their body and it creates cool wind
sweat is a mechanism to cool the body down. the body creates sweat, so it can cool itself down.
All air conditioners create condensation during the cooling process. Portable air conditioners use that condensate to improve the efficiency of the process by spraying or dripping it on the condenser coils, helping to cool them more thoroughly. This creates the vapor you are referring to which would be visible if the outside temperature is cool enough.
