4. Changes of matter
It is a physical change when there is a change of state in solid, liquid or gas. The substance changes its state by either gaining or losing energy.
It involves the following changes :
Boiling = Liquid to gas
Melting = Solid to Liquid
Subliming = Solid to Gas
Condensing = Gas to Liquid
Freezing = Liquid to Solid
Deposition = Gas to Solid

5. Changes of matter cont. Boiling = Liquid to gas
Melting = Solid to Liquid

6. Changes of matter cont. Subliming = Solid to Gas
Condensing = Gas to Liquid

7. Changes of matter cont. Freezing = Liquid to Solid
Now we are able to relate the physical changes happening around us all the time

9. Power of Hydrogen
pH measures the hydrogen ion concentration, we can determine whether solutions are acidic , basic or neutral.
