Tamara pours hot tea into a cold mug. a few moments later, she picks up the mug, and it is now warm.

what is the main form of energy transfer involved in heating the mug?

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.
