Question 6

Energy

Answer 6

In order for a substance to change state (from a solid to a liquid or liquid to a gas) it needs heat energy
As a substance changes state, it uses latent heat. There is no change to temperature, but the state of matter changes

Question 7

Answer 9

Condensation is the changing of a gas to a liquid

Question 10

Question 11

Diffusion

Answer 11
