1) All matter is made of atoms. Atoms are indivisible and indestructible.

2) All atoms of a given element are identical in mass and properties

3) Compounds are formed by a combination of two or more different kinds of atoms.

Common Examples: A rock, potato, a T.V , metal, flooring, the schools grilled cheese, gold, wood, sand, steel, brick, rock, copper, brass, apple, and aluminum foil and there's tons more.

Physical Properties: Physical properties of elements and compounds which provide conclusive evidence of chemical composition include odor, color, volume, density mass per unit volume, melting point, boiling point, heat capacity, physical form and shape at room temperature solid, liquid or gas; cubic, trigonal crystals, etc., hardness

Inter-molecular forces between the particles: The average kinetic energy of the particles in a liquid (or solid) is small enough that the forces of attraction between them is sufficient to hold the particles close together. The molecules in a liquid (or solid) do not move apart.

Physical properties: Plasmas are conductive assemblies of charged particles, neutrals and fields that exhibit collective effects.

Common examples: Welding arcs, lightning, aurorae, the excited low-pressure gas inside neon signs and fluorescent lights, solar wind, the Earth's ionosphere, stars (including the Sun), the tail of a comet, nuculer  and interstellar gas clouds.

Inter-molecular forces between the particles:

Common examples: Farts, air, helium, carbon dioxide, water vapor, burps from our body, nitrogen, oxygen, hydrogen, propane, natural gas, hydrogen sulfide, and Freon and i bet there's lots more.

Physical properties:  most gases are difficult to observe directly, they are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature.

Inter-molecular forces between the particles:  Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. The attractive inter-molecular forces between particles that tend to draw the particles together.

Common examples:

1. water

2. milk

3. blood

4. urine

5. gasoline

6. mercury (an element)

7. bromine (an element)

8. wine

9. rubbing alcohol

10. honey

11. coffee

Physical properties:

Liquids are almost incompressible. ...

Liquids have fixed volume but no fixed shape.They have fixed volume but they do not have fixed or definite shape.

Liquids flow from higher to lower level.

Liquids have their boiling points above room temperature, under normal conditions

Inter-molecular forces between the particles:  Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance.Kinetic energy tends to keep the particles moving apart. The attractive inter-molecular forces between particles that tend to draw the particles together.
