I WONDER - What Is Convection?

Convection is a heat transfer process occurring in fluids, including liquids and gases. When heated, fluids become lighter and rise, then cool down, become heavier, and sink, forming a continuous loop. This process is exemplified in a pot of boiling water, where hot water rises, cools at the surface, and sinks again, creating a circulating loop.

What is convection and in which states of matter does it occur?

Explain why hot fluid rises and what happens to it as it cools down.

Describe the process that creates a circulating loop in a pot of boiling water.

What happens to the hot water at the surface of the pot?

How does the process of convection contribute to the movement of fluids?
