| polar molecule | molecule in which the charges are unevenly distributed causing them to have a positive side and a negative side |
| mixture | material composed of two or more substances that are physically mixed together but not chemically combined |
| solution | mixture in which all the components are evenly distributed |
| solute | the substance that is dissolved in a solution |
| solvent | the substance in which another substance is dissolved to form a solution |
| suspension | mixture in which some particles cannot dissolve completely because they are too large |
| surface tension | the tightness across the surface of water caused by the polar molecules pulling on each other |
| capillary action | the combined force of the attraction amoung the water molecules with the surrounding material |
| universal solvent | water is able to dissolve many substances because it is a polar substance |
| melting | solid changes to liquid |
| evaporation | liquid changes to a gas |
| condensation | gas changes to a liquid |
| freezing | liquid changes to a solid |
