Question

How does heat transfer take place by convection? Give examples for each.

Answer 1

Convection is the transfer of heat from high energy particles to low energy particles by bulk or macroscopic movement of fluid particles over a solid surface.

Example;

• Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. ...
• Radiator - Puts warm air out at the top and draws in cooler air at the bottom.
• Steaming cup of hot tea - The steam is showing heat being transfered into the air
