Are you a diffusion expert?

Diffusion occurs in all states of matter, while osmosis only occurs in liquids

Diffusion is the movement of particles from high to low concentration, while osmosis is the movement of water molecules from low to high concentration (correct)

Diffusion only occurs through a selectively permeable membrane, while osmosis can occur through any membrane

Diffusion is a passive process, while osmosis requires energy expenditure

It increases the rate of diffusion (correct)

It has no effect on the rate of diffusion

It decreases the rate of diffusion

It only affects the rate of diffusion in liquids, not gases

Concentration gradient (correct)

The type of substance diffusing

Particle size

Changes in temperature
