Study Notes
States of Matter
- Solids are compact particles that can't be pushed closer together.
- Liquids are particles that have space between them and move freely.
- Gases are widely spaced particles that can be compressed.
- Plasma is a gaseous state containing electrically charged particles.
Physical and Chemical Properties
- Physical properties don't change a substance's chemical composition.
- Examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
- Physical changes alter state or properties without changing the chemical identity.
- Examples of physical changes include melting wax, dissolving sugar in coffee, and steam condensing into water.
- Chemical properties describe a substance's ability to change into another substance.
- Examples of chemical properties include flammability, toxicity, acidity, and reactivity.
- Chemical changes result in new substances with different properties.
- Examples of chemical changes include rust formation, nitroglycerin explosion, and combustion.
Extensive and Intensive Properties
- An extensive property depends on the amount of matter present.
- Examples of extensive properties are mass and volume.
- An intensive property is independent of the amount of matter present.
- Examples of intensive properties include temperature and density.
Classifying Matter
- A pure substance has a constant composition.
- Examples of pure substances include elements (Fe, Ag, Au, S, O, Cu) and compounds (mercury(II) oxide).
- A mixture is composed of two or more substances in variable proportions.
- Heterogeneous mixtures have non-uniform composition (examples: salad dressing, sand and water).
- Homogeneous mixtures (solutions) have uniform composition (example: sports drink).
Separation Methods
- Filtration separates solids from liquids using a filter.
- Distillation separates liquids based on boiling point differences.
- Magnetic separation uses magnets to separate magnetic solids from non-magnetic ones.
- Decantation separates liquids based on density by carefully pouring the less dense liquid.
- Sublimation separates a volatile solid from a non-volatile solid by directly converting the volatile solid to gas.
- Chromatography separates components based on their ability to adsorb to a stationary phase.
- Physical manipulation involves physically separating components in a mixture.
