Question

Which graph correctly shows the effect of heat energy on the motion of molecules of matter?

Answer 1

That is wrong it is graph 3

Answer 2

Answer: Graph 3 shows the correct effect of heat energy on the motion of molecules of matter.

Step-by-step explanation:

The energy related to the motion of the particles is related to the kinetic energy of the particles. Kinetic energy of the particles depend upon the temperature.

`\text{Kinetic energy}\propto \text{Temperature}`

As, kinetic energy is directly proportional to the temperature. Increase in temperature would result in the increase of kinetic energy which increases the motion of molecules of matter and vice-versa.

Hence, the correct representation will be Graph 3.
