AP Chemistry / Unit 3: Properties of Substances and Mixtures
3.3 Solids, Liquids, and Gases
Notes
- Solids: fixed shape and volume. Liquids: fixed volume. Gases: neither.
- Stronger IMFs mean higher boiling points and lower vapor pressure.
Practice
A liquid with weak IMFs has:
Molecules escape easily.
Particles in a gas are:
Mostly empty space.
A liquid boils when its vapor pressure equals:
Definition of boiling.
