| Question | Answer |
|---|---|
| Atom | the smallest particle of an element that still retains properties of elements |
| matter | anything that has mass and takes up space (volume) |
| Physical Property | any characteristic of a material that you can observe without changing the identity of the substance |
| Chemical Property | any characteristic of a substance that can be observed during a chemical reaction |
| mass | amount for matter in an object |
| volume | the amount of space an object takes up |
| density | amount of matter (mass) in a given space (volume) |
| Physical Change | a change in size, shape, or state of matter in which the identity of the substance remains the same |
| Chemical Change | change of one substance into a new substance |
| solid | state of matter with a fixed volume and shape; atoms very tightly packed together with only movement being vibration |
| liquid | state of matter with a fixed volume, but no fixed shape; atoms are not as tightly packed as solid allowing the fluid can flow |
| gas | state of matter with no fixed volume or shape; in which atoms are very loosely packed |
| Phase Change | a physical change when matter changes form one state to another (solid, liquid, gas) |
| freezing | liquid to solid |
| melting | solid to liquid |
| melting point | tempature at whcih solid begins to become liquid |
| evaporation | liquid to gas |
| boiling point | tempature at which a liquid begins to boil (turn into gas) |
| condensation | gas to liquid |
| sublimation | solid to gas |
| deposition | gas to solid |
| pure substance | substance with all identical particles; composed entirely of the same element or same compound |
| mixture | a substance created by mixng two or more pure substances together |
| element | pure substance where all atoms are identical |
| compound | pure substance in which two or more elements are chemically combined |
| homogeneous mixture | mixture that is blended uniformly, appears to be one substance |
| heterogeneous mixture | mixture where the individual componenets are easily seen |
| solution | well mixed homogenous mixture where individual particles cannot be seen with a microscope |
| solvent | in a solution it is the substance in which a solute dissolves |
| solute | the substance being dissolved in a solution |
| dissolve | when a solid joins together with a liquid to form a solution |
