Question

Which condition must exist in order for conduction to occur between two substances?

O The molecules of the substances must be touching.
OBoth substances must be the same temperature.
At least one substance must be a liquid.
Most of the molecules must be slow moving.

Answer 1

Conduction occurs when heat is transferred between substances in direct contact with each other.

Step-by-step explanation:

Conduction occurs when heat is transferred between two substances that are in direct contact with each other. It does not require the substances to be liquids, but can occur between solids or between solids and liquids. The important factor for conduction is the temperature difference between the substances.
