Question

What is convection explain your answer properly and state an example

Answer 1

Answer: Convection is the transfer of heat due to the bulk movement of molecules within fluids, including molten rock. Convection includes sub-mechanisms of advection, and diffusion. Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place. EX :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
