Question

During which process does heat transfer occur because of density differences in water or air?

Answer 1

Answer: D. Convection

Explanation: As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes denser and sinks.

Answer 2

Answer:

The correct answer is D. Convection.

Explanation:

Convection occurs due to the differences in density, and only happens in gases or liquids. The heat is transferred by the movement of a heated fluid, which is air or water.
