The heat transfer by conduction is proportional to:
Correct answer: A. Temperature difference
- A. Temperature difference
- B. Pressure difference
- C. Volume change
- D. Entropy change
Explanation
According to Fourier's law, heat transfer by conduction is proportional to the temperature difference across the material, driving the flow of heat from hot to cold regions.

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.
