Answer: Check explanation.

Explanation:

Let us start by defining what conduction is. The transfer of heat energy by contact is known as CONDUCTION. Conduction is the transfer of energy from higher region to one of lower the lower region.

At an advance level, studies have shown that Conduction occurs in all the three state of matter, that is solid, liquid, and gas. Although, conduction work best in solids. In solids, Conduction take place due to transfer of electrons and due to lattice vibrations.

For conduction to occur there must be temperature difference. Heat is transferred from the one of higher heat to the region of lower heat. And the substance must be in contact.
