Question

Name two process which provides the best evidence for the motion of particles in matter

Answer 1

Brownie motion and diffusion are the two processess which provides the best evidence for the motion of particles in matter.

Answer 2

Explanation:

The two processes that describe the motion of particles in matter are Brownian movement and diffusion.

Brownian movement is the movement in which particles of fluid randomly move from one place to another and thus, they collide with each other.

Whereas in diffusion of gasses, particles are held together by weak Vander waal forces thus, there is more collision between the particles and hence, particles move from their initial place.
