Matter: Anything that occupies pace and has mass.
Examples: Solids, liquids, gases, mixtures, and substances
Physical Properties: Properties that can be observed and measured without changing the chemical makeup of the substance.
Examples: Freezing Point, Melting Point, Density, and Boiling Point.
Density: The mass of material within a given volume.
Freezing Point: Another physical property.
Aqueous Solution: A water-based solution that is based on the Latin root for water.
Mixture: The result of two or more substances combine and yet the substance retain their individual properties; a type of matter where two or more physically separable components in ratios varying from sample to sample.
Examples: Heterogeneous Mixture, Homogeneous Mixture.
Heterogeneous Mixture: Not the same, or uniform; varying properties from sample to sample.
Examples: Colloids and Suspensions
Homogeneous Mixture: Uniform properties throughout.
Examples: Solutions and Substances
Substances: Homogenous; definite composition and not physically separable.
Elements: One type of atom; type of substance.
Compounds: Two or more types of atoms chemically bonded; type of substance.
Tyndall Effect: The scattering of light.
Colloids: Often suspended microscopic particles; exhibit Tyndall effect.
Solutions: Homogenous mixtures that are often molecular sized particles which usually pass light.
Solute: The dissolved substance
Solvent: The dissolving agent.
Questions:
Why can't foul water lab make seawater drinkable?
- It would take too long and the the lab was to make foul water capable for hand washing and not drinking.
What process can?
Distillation: purifying a liquid by vaporizing it.
OR
Desalination: the removal of salt from seawater.
