1. Intermolecular forces
2. Liquid structure
3. Solid structures
4. The impact on materials
Atomic and molecular properties – the structure and properties of bulk solids and liquids
New materials by considering how the properties and interactions of individual particles give rise to bulk properties
The forces between molecules govern the physical properties of bulk matter and help to account for the difference in the substances
Attractions and Repulsions
Gases vs. liquids & solids:
Molecules are far apart in gases, intermolecular attraction is not important.
It is important for liquids and solids in which molecules touch.
Intermolecular forces = the forces between molecules.
Even though we use the word ‘force’, we actually mean potential energy.
