Question

b) Can you explain why smoke always rises up?
​

Answer 1

Answer:

Smoke always rises up because it is less denser than air. It is because smoke is lighter than air . A fire makes things hot. Therefore the temperature of smoke is higher than th atmosphere and as hot air rises up smoke too rises into the air.

Answer 2

Answer:

This is because of the heating of the earth's surface during the day. The air just above the surface becomes heated and expands. In turn, it begins to rise, since it is lighter, resulting in vertical movement in the atmosphere. The more unstable, the higher smoke will be lifted.
