<h2>Right answer: Warm air rises and takes heat with it; eventually it cools and sinks.
</h2>
There are three ways in which heat is transmitted:
1. By Conduction, when the transmission is by the direct contact through collisions
2. By Convection, heat transfer in fluids making a current created by less dense fluids floating and more dense fluids sinking (like water or the air, for example).
3. By Radiation, by the electromagnetic waves, which can travel through any medium or without a medium (vacumm)
In this case the situation that best describes <u>convection</u> is Warm air rises and takes heat with it; eventually it cools and sinks.
