Which condition must exist in order for conduction to occur?

A. The molecules of the substances must be touching.
B. Both substances must be the same temperature.
C. At least one substance must be a liquid.
D. Most of the molecules must be slow moving.



Answer :

Final answer:

Conduction is the transfer of heat through physical contact between particles. It relies on molecular interactions and temperature differentials for efficient heat transfer.


Explanation:

Conduction is the process of heat transfer through stationary matter by physical contact. It occurs when rapidly moving or vibrating atoms and molecules transfer kinetic energy to neighboring particles. For conduction to occur, the molecules of the substances must be in contact, and temperature differences play a crucial role in the rate of heat transfer.
