Question

which term is used to describe why we can smell air freshener across the room shortly after it has been sprayed?
elastic collisions
osmosis
diffusion

Explanation:

To determine the term, we analyze each option:

• Elastic collisions: Involve collisions where kinetic energy is conserved, not related to smell spreading.
• Osmosis: Is the movement of solvent molecules across a semipermeable membrane, not applicable here.
• Diffusion: Is the movement of particles from an area of high concentration to low concentration, which explains how air freshener particles spread across the room so we can smell them.

Answer:

The correct option is the one labeled "diffusion" (the third option in the list, assuming the options are presented as: A. elastic collisions, B. osmosis, C. diffusion, so C. diffusion).
