C and P Matter
Matter Unit 1
| Question | Answer |
|---|---|
| Compound | substances formed from two or more elements in which the exact combination and proportion of elements is always the same |
| Density | mass per unit volume of a material |
| Dependent/Responding Variable | factor that changes as a result of what was deliberately changed(independent variable) |
| Element | substances with atoms which are all alike |
| Freezing point | the temperature at which a liquid solidifies |
| Independent/Manipulated Variable | the factor that is deliberately changed |
| Heterogeneous | mixture in which different materials are unevenly distributed and are easily identified |
| Homogeneous | solid, liquid or gas that contains two or more substances blended evenly throughout |
| Mass | the amount of matter in an object |
| Matter | anything that has mass and takes up space |
| Melting point | when the particles of a solid gain enough kinetic energy to slip out of their ordered arrangement |
| Mixture | a portion of matter consisting of two or more components in varying proportions that retain their own properties |
| Physical Change | any change in size, shape, or state of matter in which the identity of the substance remains the same |
| Physical Property | any characteristic of a material, such as size, shape, color, density, solubility, odor, melting point, boiling point that you can observe or attempt to observe without changing the identity of the material |
| Saturated Solution | any solution that contains all of the solute that it can hold at a given temperature |
| Scientific Method | an organized set of investigation procedures |
| Solubility | maximum amount of solute that can be dissolved in a given amount of solvent at a given temperature |
| Solute | the part of a solution that is dissolved |
| Solution | mixture that appears to have the same composition, color, density, and taste throughout and is mixed at the molecular level |
| Solvent | the part of the solution that does the dissolving |
| Supersaturated Solution | any solution that contains more solute than a saturated solution at the same temperature |
| Unsaturated Solution | any solution that dissolve more solute at a given temperature |
| Volume | the amount of space occupied by an object |
| Weight | gravitational force exerted on an object |
