Question

identifying the method of thermal energy transfer
when an ice pack is applied to an injury, thermal energy from the injured area transfers to the ice, causing the blood vessels within the area to constrict, which reduces the swelling.
how is thermal energy transferred in this scenario?
conduction
convection
radiation

Explanation:

In this scenario, the ice - pack is in direct contact with the injured area. Heat transfer through direct contact is conduction. Convection involves the movement of fluids and radiation is heat transfer through electromagnetic waves. Since there is direct contact here, it is conduction.

Answer:

conduction
