Question | Answer |
---|---|
Matter that always has exactly the same composition | Pure Substance |
A substance that cannot be broken down into simpler substances | Element |
The smallest particle of an element | Atom |
A substance that is made from two or more simpler substances and can be broken down into into simpler substances | Compound |
The parts of the mixture are noticeably different from one another | Heterogeneous Mixture |

When substances dissolve and form a homogeneous mixture, the mixture is the solution | Solution |
A heterogeneous mixture that separates into layers over time | Suspension |
Contains some particles that are intermediate in size between the small particles in a solution and the larger particles in a suspension | Colloid |

The temperature at which a substance changes from solid to liquid | Melting Point |
The temperature at which a substance boils | Boiling Point |
The process that separates materials based on the size of their particles | Filtration |
The process that separates the substance in a solution by their boiling points | Distillation |
Occurs when some of the properties of a material change but the substance in the material remains the same | Physical Change |
Any ability to produce a change in the composition of matter | Chemical Property |
A material's ability to burn in the presence of oxygen | Flammability |
The property that describes how readily a substance combines chemically with other substances | Reactivity |
Occurs when a substance reacts and forms one or more new substances | Chemical Change |
