Question

Explain the process of convection with the help of an example answer for science

Answer 1

Convection is a type of heat transfer that can only happen in liquids and gases, because it involves those liquids or gases physically moving.

Convection happens when there is a difference in temperature between two parts of a liquid or gas. The hot part of a fluid rises, and the cooler part sinks. But let's use an example to think about why it happens, lest we assume that the fluid has a mind of its own.
