Physical Science

What are the Pure Subtances:

• Elements and Compounds

• Homogeneous and Heterogeneous

• Clloids and Suspension

• Hydrogen and Fusion

Made of one type of atom. Cannot be broken down further.

• Compounds

• Elements

• Compound

• Hydrogen

2 types of mixture

• Homogeneous Mixture and Heterogeneous Mixture

• Colloids mixture and Subtance Mixture

• Hydrogen and Helium

• Boron mixture and Carbon Mixture

Made of two or more elements chemically combined. Can be broken down into simpler substances.

• Compounds

• Elements

• Homogeneous

• Heterogeneous

Uniform composition throughout particles are very small and do not settle.

• Colloids mixtures

• Homogeneous Mixtures

• Heterogeneous Mixtures

• Subtance Mixtures

Non- uniform composition; different parts can be seen.

• Subtances Mixtures.

• Colloid Mixtures

• Homogeneous Mixture

• Heterogeneous Mixtures

Particles are larger than in solutions but still do not settle out.

• Colloids

• Subtances

• Homogeneous

• Heterogeneous

Large particles that can settle over time if left undisturbed.

• Suspensions

• Subtances

• Colloids

• Heterogeneous

Solid to liquid. Requires heat energy.

• Freezing

• Vaporization

• Submilation

• Melting

Gas to solid. Skips liquid phase.

• Freezing

• Melting

• Deposition

• Condesation
