Question

How is energy transferred by convection?

What are convection currents?

Answer 1

It is heat transfer as a result of density difference.

It is movement caused within fluids. Fluids are liquids or gas.

Example- Boiling water.

Particles near fire gain kinetic energy from the fire so they move fast and spread out. They rise up and cooler particles from the top fills in the bottom space. But then the cooler fluid also gains energy and rises up. This process keeps on going.

Convectional current is the motion of convection.

Answer 2

Convection is transferred by mass motion of a fluid such as air or water when heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises.

Step-by-step explanation:

A current in a fluid that results from convection.
