Answer 25

A change of state

Question 26

What is diffusion?

Answer 26

The movement of particles from a high to low concentration

Question 27

What three factors affect the rate of diffusion?

Answer 27

Temperature Particle Size The state of the substance that is diffusing

Answer 28

Gas

Question 29

In which state does diffusion not happen?

Answer 29

Solid

Question 30

How does temperature affect diffusion?

Answer 30

The higher the temperature, the faster the rate of diffusion.
