Question

Molecules of two solid substances actually collide with each other to transfer energy in this method of heat transfer.

A)
conduction


B)
convection


C)
insulation


D)
radiation

Answer 1

A

Step-by-step explanation:

The correct option is; A) conduction

Conduction is the direct transfer of energy through the movement of substances that are in contact with each other. For example in heat conduction, the process occurs when the temperature of the molecules present in a substance increase which causes vigorous vibration. The molecules then collide with other molecules that are closer to them, making them vibrate too. This causes the flow of heat energy to adjacent part of the object. Types of energy that can be transferred through conduction are heat, electrical and sound energy.
