Question

there are three ways that heat can be transferred from one place to another. in order for heat to be conducted, what must happen? the heat must be transferred by direct contact (touching) the heat must transfer through the air or through a vacuum by either convection or radiation

Explanation:

Heat conduction is a mode of heat transfer where heat moves through direct contact between particles. Convection involves heat transfer through fluids (liquids or gases) and radiation is heat transfer via electromagnetic waves (can occur in vacuum). The question asks specifically about conduction.

Answer:

the heat must be transferred by DIRECT CONTACT (touching)
