Question

in the context of heat transfer, which statement about conduction is most accurate? d) heat transfer requires direct physical contact b) metals conduct heat more effectively than air a) heat transfers equally in all materials c) conduction occurs only in solid materials

Explanation:

Conduction is a mode of heat transfer that occurs through direct physical contact between particles. Metals have a high density of free - electrons which makes them better conductors of heat compared to air. Heat does not transfer equally in all materials as different materials have different thermal conductivities. Conduction can occur in liquids and gases as well, not just solids.

Answer:

B. Metals conduct heat more effectively than air, D. Heat transfer requires direct physical contact
