Answer: Conduction
Step-by-step explanation: There are three modes of heat transfer.
1. Conduction: This type of heat transfer happens when there is direct contact between the two object.
2. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).
3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
Thus heat being transferred from the heating element to the pot to the boiling water is an example of conduction as the they are in direct contact with each other.
