The kinetic model theory of matter states that all made is made up of a large number of tiny atoms or molecules which are in continous motion.

 

The existence of particles in continous motion has been demostrated by Browian motion and diffusion. 

In browian motion demostration we can see that when the temperature is higher, the motion of small particles in the air become more vigorous. This is because the surrounding air particles are moving faster and hitting the smoke particles more frequently and with greater force. 

When temperature increases thermal energy is transferred to the molecules and the molecules gain kinetic energy.
