• A. Perfume particles move from high concentration area to low concentration area.
• B. Perfume particles spread through the gaps between the air particles.
• C. Perfume particles undergo diffusion.
• D. Perfume particles pass on their fragrance to air molecules.

Answer 1

Answer: (A), (B), (C)

The correct options are
A

Perfume particles move from high concentration area to low concentration area.

B

Perfume particles spread through the gaps between the air particles.

C

Perfume particles undergo diffusion.

Whenever a bottle of perfume is opened in one corner, we can identify its smell across the room because the particles of the perfume are high in concentration in the bottle and their concentration is lower outside. So they spread from area of high concentration to the area of low concentration in the air around, through the gaps between the molecules of air in the room. This process is known as Diffusion.
