Answer 1

Answer:

Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water.

answer (in one word):- expands

Answer 2

The reason for hot air moves to upward direction because higher the temperature, lesser the density / weight.
