Particles in Motion

Diffusion الإنتشار: the movement of particles from an area of

• higher concentration to area of lower concentration. ​

• lower concentration to area of higher concentration. ​

what is Temperature:

• the measure of the average kinetic energy

• the measure of the potential energy

• When  temperature increase particles will collide more so the volume of a material will increase.
