Question

how does diffusion work when air freshener is sprayed in a room?
the air molecules will move with the concentration gradient.
all of these answers are correct.
eventually, the air freshener molecules will reach equilibrium throughout the entire space.
the air freshener molecules will move from a high concentration to a low concentration.

Explanation:

• Diffusion is the movement of molecules from an area of high concentration to an area of low concentration (so the statement “The air freshener molecules will move from a high concentration to a low concentration” is correct).
• This movement occurs along the concentration gradient (so “The air molecules will move with the concentration gradient” is correct as the air freshener is part of the air - molecule system in this context).
• Eventually, after diffusion, the air freshener molecules will be evenly distributed (reach equilibrium) throughout the space (so “Eventually, the air freshener molecules will reach equilibrium throughout the entire space” is correct).

Answer:

B. All of these answers are correct.
