Conduction. Conduction is the transfer of heat through touch. The hot tea gave some heat to the cold mug by touching the mug, therefore it is conduction.

Answer: Conduction

Explanation: MODES OF HEAT TRANSFER

Conduction: This type of heat transfer happens when there is direct contact between the two object.


Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).


Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

Thus as there is direct contact between the mug and the tea, the heat transfer occurs through conduction.
