What are the two types of changes?
Physical and chemical changes
Describe what is a physical change.
A physical change does not change the nature of the substance. (The changes can be irreversible and reversible)
Describe what is a chemical change
A chemical change changes the nature of the substance. ( The Changes are irreversible )
What are the six phase changes?
1) Melting (Solid to liquid)
2) Freezing (Liquid to Solid)
3) Sublimation (Solid to Gas)
4) Condensation (Gas to Liquid)
5) Evaporation (Liquid to Gas)
6) Deposition (Gas to Solid)
What is synthesis?
Joining Together
What is Decomposition?
