6) Cooling blankets and ice packs cool core body temperature through the mechanism known as:

1. conduction.
2. diffusion.
3. convection.
4. radiation.

The correct answer is:

conduction.

Explanation:

Cooling blankets and ice packs work by conduction, which involves the direct transfer of heat from the body to a cooler object (e.g., the blanket or ice pack) in physical contact with the skin. Heat moves from the warmer body to the cooler object until thermal equilibrium is reached.

Why not the other options?

1. Diffusion: Refers to the movement of particles (like gases or liquids) from an area of higher concentration to lower concentration, not heat transfer.
2. Convection: Involves heat transfer through the movement of air or liquid (e.g., a fan or cool water circulating over the body).
3. Radiation: Involves heat transfer through electromagnetic waves without direct contact (e.g., losing heat to the cooler environment).
