Which statement explains what happensto the water in the pot?
The water temperature decreases inside the pot.
The water will freeze when enough heat is added.
Heat is transferred from the water in the pot to the burner.
Heat is transferred from the burner to the pot and then to the water
What is heat is transferred from the burner to the pot and then to the water?
It is the transfer of heat within a liquid, or gas.
What is convection?
