Conduction

Explanation:

Conduction is the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. When a pot of water is placed on the stove to boil, conduction heat warms up the pot, which then heats the water molecules inside.
