Where does the heat go from a cup of hot cocoa sitting on the table?
Hot air rises.
Why can you feel a match burn when you put your hand above but when it's underneath you can't?
Hot air rises.
What happen when air gets heated?
As air (unconfined), is heated its volume increases, and its density decreases. That makes it lighter (per volume) than it was. Warm air will rise above colder air, and in essence, float on top of the colder air.
How do hot air balloons stay in air?

How can a hot air balloon move towards the wind?
hot air rises up
When hot and cold air meet the hot air rises to the top. Which process causes the hot air to rise?
Convection
How does hot air rise?
Hot air rises because it is less dense than cold air.
How does warm air balloons float?
"Warm air", otherwise known as Hot Air Balloons, float because of one basic Law of Thermodynamics; heat rises. The air in a hot air balloon is hot, therefore, the balloon rises.
How does the air density inside a balloon change as it rises from the ground to the air?
The air density inside a balloon changes as it rises because the hot air inside the hot air balloon is less dense than the air around it causing it to fly since hot air rises. But as it rises it loses its hot air causing it to eventually not be able to fly anymore and come down.
What is it called when hot and cold air meet and the hot air rises to the top?
it forms a tornadow
