| A | B |
|---|
| water vapor | water changing from a liquid to a gas |
| molecules | the smallest particles of water |
| mixture | two or more substances that combine and keep their own properties |
| oceans | where most water evaporates from |
| droplets | form when air is cooled and water molecules move more slowly |
| cohesion | the ability of water molecules to attach to other water molecules |
| density | ice floats when water freezes because the hydrogen bonds spread out and trap air |
| capillary action | the ability of water to move up through a tube by attaching to its surface, how water moves up through a plant |
| solutions | all the molecules of the dissolved substance spread out evenly |
| solid | what water becomems when the temperature decreases |
| Polarity | Negative Oxygen and Positive Hydrogen |
| covalent bond | the hydrogen and oxygen of a water molecule bind with this strong bond where electrons are shared |
| surface tension | the force holding water molecules together at the top to form a kind of skin |
| Hydrogen Bond | water binds to other water molecules with this weak bond |
| water cycle | water moving throught the atmosphere, hydrosphere, and lithosphere |
| Water Molecule contains | 2 hydrogen and 1 oxygen |
| Heat Capacity | property of water in that water can hold a lot of heat energy without changing the temperature of the water |
| Great Solvent | because of its polarity water can dissolve other polar substances (not fats) |
| adhesion | the ability of water to attach to other molecules than itself |
| solute | a molecule/compound that can dissolve in water or a solvent |
