Study Notes
Key Concepts in Chemistry
- Matter: Anything that has mass and occupies space.
- Pure Substance: Matter made of only one type of particle.
- Mixture: Matter made of more than one type of particle.
- Solution: A homogeneous mixture, where the components cannot be distinguished.
- Mechanical Mixture: A heterogeneous mixture, where the components can be distinguished.
- Solute: A substance that dissolves in a solvent.
- Solvent: A substance that dissolves a solute.
- Dissolving: The process where a solute mixes with a solvent to form a solution.
- Rate of Dissolving: The speed at which a solute dissolves in a solvent.
- Solubility: The ability of a substance to dissolve in a solvent.
- Concentration: The amount of solute in a given amount of solvent.
- Particle Theory: The theory that all matter is made up of tiny particles in constant motion, with space between them.
Changes of State
- Melting: Solid to liquid.
- Freezing: Liquid to solid.
- Evaporation: Liquid to gas.
- Condensation: Gas to liquid.
- Factors Affecting Rate of Change: Temperature, stirring, and particle size
- Attractive Forces: The strengths of attraction between particles: stronger forces mean they stay closer together.
Separating Mixtures
- Filtration: Separating a solid from a liquid by using a filter.
- Evaporation: Separating a solid from a liquid by evaporating the liquid.
- Distillation: Separating liquids with different boiling points by heating and condensation.
- Chromatography: Separating mixtures of dissolved substances based on their attraction to different materials.
- Sorting: Separating mixtures by sorting components based on size, shape, color, or other properties.
- Sifting: Separating materials based on differences in particle size.
- Magnetism: Separating materials based on magnetic properties.
