1
Music Here we have an electric hot plate.
2
When a pot of water is placed on the hot plate, the pot is in contact with the hot plate and the heat moves via conduction from the hot plate to the pot.
3
Inside the pot, the water at the bottom is heated.
4
It rises as it is heated and then falls as it is cooled.
5
A current forms which distributes heat via convection throughout the pot.
6
When held at a distance from the hot plate, heat continues to move via radiation.
