| Question | Answer |
|---|---|
| the tendency of a liquid to keep from flowing; resistance to flowing. | viscosity |
| any characteristic of a material that can be observed or measured without changing the composition of the substances in the materal. | Physical Property |
| a materals abilty to allow heat or electric charges to flow. | Conductivity |
| the temperature at which a substance changes from a soloid to a liquid. | Melting Point |
| the abilaty of a soloid to be hammered without shattering. | Malleability |
| the temperature at which a supstance boils; the temperature at which vapor pressure is equal to amospheric. | Boiling point |
| a process that separates mateials based on the size of their particles. | filtration |
| a process that separates the substances in a solution based on their boiling points. | Distillation |
| a change that occurs when some properties of a material change, but the substances in the material stay the same. | Physical change |
| a mixture that forms when substances dissolve and/or form a homogeneous mixture. | solution |
| A type of mixture in which the parts of the mixture are noticcably diffrent from one another. | Heterogeneous mixture |
| A homogeneous mixture that separats into layers over time. | Suspension |
| matter theat always has exactly the same composition an element or a compound. | pure substances |
| a substance that cannot be broken down into simpler substances. | Element |
| a type of mixture in which the substances are so evenly distributed that it is difficult to distinguish one substances in the mixture from another. | Homogeneous mixture |
| a substance that is mad from two or more simpler substances and can be broken down it those simpler substances. | compound |
| the smallest particle of an element. | atom |
| a mixture that contains some particles that are intermediate in size between the small particles in a solution. | colloid |
