What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low concentration.
• no movement 
• molecules move everywhere

Diffusion occurs only in solids

• True

• False

How long does diffusion last?

• Until the concentration of particles in the system is equal

• Until a region in the system has a smaller concentration of particles than the other

• Until a region in the system has a greater concentration of particles than the other

• Until the particles disappear from the system

How does an increase in temperature affect diffusion?

• Diffusion speeds it up

• Diffusion slows it down

• Diffusion has no effect
