Question

8. How will you show that hot air goes up?​

Answer 1

Hot air rises - UCSB Science Line 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.
