Lesson 6: Pure Substances & Mixtures (Matter & Its Interactions)

Terms in this set (18)

Chromatography
A technique that is used to separate a single substance from a mixture of many different substances if that substance has physical properties that are distinctly different from the other substances in the mixture.
Component
One substance that is part of a mixture.
Compound
Matter that can be broken down by a chemical reaction into its elements.
Condense
The process by which a gas turns into a liquid.
Crystal
A solid that contains atoms arranged in an organized way.
Dissolve
The process during which a homogenous mixture forms. The particles of the dissolved substance (solute) spread evenly throughout the dissolving substance (solvent), so that they are no longer visible.
Distillation
A method of separating a liquid mixture through boiling and evaporation
Evaporate
To change from a liquid to a gas at or below the boiling point.
Heterogeneous Mixture
A mixture in which there is uneven mixing.
Homogeneous Mixture
A mixture in which all of the components are evenly mixed.
Mixture
Matter in which two or more substances (elements or compounds) are mixed together without breaking or making new bonds between atoms.
Model
A tool scientists and engineers use to represent ideas or provide an explanation. Models may include diagrams, drawings, physical replicas, mathematical representations, analogies, or computer simulations.
Physical Property
All the characteristic properties of a substance that can be measured or observed without changing the type of matter.
Pure Substance
A sample of matter that is not mixed with any other types of matter.
Separations
Techniques chemists use to purify atoms and molecules.
Solute
A substance that dissolves in another substance.
Solution
A type of homogeneous mixture formed when one substance (the solute) dissolves in another (the solvent).
Solvent
The substance in which another substance dissolves.
