A. Latent heat of vaporization of the liquid
B. Increased vibration of the molecules of the liquid about theit mean position
C. Variation of density of the liquid
D. Expansion of the liquid as it is heated
Correct Answer:
Option D – Expansion of the liquid as it is heated
Explanation
Liquids and gases expand when they are heated. The liquid or gas in hot areas is less dense than the liquid or gas in cold areas, so it rises into the cold areas.
