Question

Heat that flows by conduction is the transfer of thermal energy between substances in contact. What must occur for this to happen?

Answer 1

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.

Answer 2

Is this the full question?

Heat that flows by conduction is the transfer of thermal energy between substances in contact. For this to happen, what must occur?

A) The two systems must be the same temperature.
B) The two systems must not be touching each another.
C) One system must have higher kinetic energy than the other system.
D) The thermal energy of one system must be the same as the thermal energy of the other system.
