Question

what is the definition of thermal conductor

Explanation:

A thermal conductor is defined based on its ability to transfer thermal energy. We analyze each option:

• Option 1: Substances that thermal energy cannot move through are insulators, not conductors.
• Option 2: Substances that thermal energy can easily move through fits the definition of a thermal conductor.
• Option 3: The process of thermal energy transfer by electromagnetic waves is radiation, not related to the definition of a conductor.
• Option 4: Condition caused by the loss of too much body heat is hypothermia, not relevant to the definition of a thermal conductor.

Answer:

Substances that thermal energy can easily move through.
