| evaporation | the process by which liquid becomes a gas |
| water vapor | water in its gas form |
| saturated | when the air cannot hold any more water vapor |
| What evaporates faster - warmer or cooler water? | Warmer water evaporates faster |
| What evaporates faster - water with a larger or smaller surface area? | Water with a larger surface area evaporates faster |
| How does increasing the speed in which water molecules move affect the evaporation rate? | Molecules that move faster hit each other harder and break away faster, which means they evaporate faster |
| surface area | the amount of space covering the topmost layer of water (or land) |
| controlled variables | variables in an experiment that are not allowed to change |
| independent variable | the variable in an exepriment that you change |
| dependent variable | what you find out by doing an experiment |
| condensation | the process by which water vapor changes into liquid water |
| frost | frozen condensation; appears on surfaces when the temperature drops below the freezing point at night |
| dew | liquid condensation; appears on surfaces when the temperature drops at night |
| freezing point | the temperature at which a liquid turns in a solid; for water - 32° F or 0° C |
