Question

Whenever a bottle of perfume is opened in a corner, we can receive its smell across the room. Choose the correct option(s) of what happens in this process.

• A. Perfume molecules move from high concentration area to low concentration area.
• B. Perfume molecules spread through inter molecular space
• C. The molecules diffuse.
• D. they are carried by the person who opens the bottle.

Answer 1

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

The correct options are
A

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

B

Perfume molecules spread through inter molecular space

C

The molecules diffuse.

Whenever a bottle of perfume is opened, we can receive its smell across the room because the essence particles which remain at very high density and pressure inside the bottle spread out immdiately due lower density outside. The molecules spread from high concentration region to low concentration region quickly through inter-molecular space in the surrounding. This process is known as Diffusion.
So, all the options are correct.
