Question

ok i just realised this , if water and air are bad conductors of heat then how does convection occur in them ? You are pretty smart if you can give me an explanation , thanks :)​

Answer 1

Answer:

The convection happens because hot water has a lower density and thus rises up to the surface where it cools and sinks down to the bottom again. When water starts boiling there is the additional effect of the formation of water vapor bubbles that have a much stronger buoyancy than hot water
