Which of the following will rise the highest?
  1. Air at 10oC
  2. Air at 40oC
  3. Air at 15oC
  4. Air at 5oC

Air at 40oC
Air at 15oC
Air at 10oC
Air at 5oC
Verified by Toppr

In hot air, the particles have higher kinetic energy and hence less density, so the air with the highest temperature will rise the highest.
Therefore, air at 40oC will rise the highest.
