Answer:

Why do hotter substances have a tendency to rise?

Step-by-step explanation:

The molecules heats up and moves fast, since the air is less dense than the surrounding then the hot air floats upward.

The transfer of heat will continue as long as there is a difference in temperature between the two locations. Once the two locations have reached the same temperature, thermal equilibrium is established and the heat transfer stops.
