The thermal conductivity of a material is highest for:
Correct answer: C. Metals
- A. Gases
- B. Liquids
- C. Metals
- D. Insulators
Explanation
Metals have high thermal conductivity due to free electrons that efficiently transfer heat, unlike gases, liquids, or insulators, which have lower conductivity.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
