Question

Explain what happens to particles in diffusion. What causes diffusion?

Answer 1

Diffusion:
in diffusion particles move from area of higher concentration to the area of lower concentration..
causes:
the movement of particles allow them ti disperse,,, when molecules are close to each other they collide with each other and push each other apart so they spread in the whole area... :)

Answer 2

 Diffusion is the process of water molecules from a high concentration region to low concentration.When particles diffuse ,they will break down to simpler particles.
Causes:
Due to the motion of paticles the particles will collide each other and mix.
