Question

Thermal conduction can take place in:

• A. solids only
• B. liquids only
• C. gases only
• D. All of the above.

Answer 1

The correct option is D All of the above.

Thermal conduction is considered as the transfer of heat across a substance by microscopic collisions of particles and movement of particles within that substance. Since all solids, liquids and gases are composed of tiny particles, these particles collide constantly and help in the transfer of heat energy.
