Solids
- Particles are tightly packs and close together, also they do not move very much.
- Definite shape and volume
- Most solids are crystals
- Crystals are made up of unit cells…( repeating patterns )
- When put together unit cells make up the "skeleton" of the crystal.
- 7 different types of crystals, cubic, tetragonal, orthorhombic, monoclinic, triclinic, hexagonal, and rhombohedral.
Amorphous Solid
- Solid that has no defined shape, since no defined shape it is not a crystal.
- Lacks internal structure.
Allotropes
- Solids that appear in more than one shape
- 2 or more different molecular forms of the same element in the same physical state have different properties.
liquids
- Particles are spread a part more than the solids, and move at a slow pace in the container.
- No definite shape, but a definite volume
- Flow from one container to another
- Viscosity- resistance of a liquid to flowing ( honey = high viscosity, water = low viscosity)
