How do the particles move in diffusion?

• From a region of low concentration to a region of high concentration

• From a region of high concentration to a region of low concentration

• From a region of low concentration to a region of low concentration

• From a region of high concentration to a region of high concentration

The movement of particles is __________, resulting in the particles being spread throughout the container

• Structured

• In a straight line

• Random

• In curved, way motions

The picture  is an example of _________________.

• isotonic
• diffusion
• osmosis
• active transport

Diffusion occurs only in solids

• True

• False

What happens to particles when they are heated?

• They speed up and spread out
• They slow down and compress
• They stop moving
• They move closer together and speed up

What happens to the coffee particles when coffee is added to hot water?

• They sink to the bottom of the cup

• They spread out

• They clump together

When does diffusion stop?

• After a day and a night

• When the particles are evenly spread out

• When there are no particles left

• When all the particles leave the system

An increase in temperature does what to diffusion?

• Speeds it up
• Slows it down
• Has no effect
• I wish i knew. Really I do.
