• False

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

How long does diffusion last?

• Until the concentration of particles in the system is equal

• (Select this answer and I swear i'll make it harder for you in the assessment task)

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

• Until the particles disappear from the system
