• A. diffusion
• B. brownian motion
• C. saturation

Answer 1

Answer: (A), (B)

The correct options are
A diffusion
B brownian motion

Diffusion refers to the movement of particles from an area of high concentration to an area of low concentration. It occurs in liquids and gases because the molecules are in constant random motion. Inside the deodorant, the particles are present at a very high concentration under pressure. Once released, they spread out in every direction since the concentration of the particles is lower everywhere outside the can.
