| Question | Answer |
|---|---|
| Water | A chemical substance made of hydrogen and oxygen that is essential for life, it can be a solid, liquid, or gas. |
| Capillary action | The ability of water to move upward through narrow spaces without the help of gravity due to cohesion and adhesion. |
| Cohesion | The attraction between molecules of the same substance. |
| Adhesion | The attraction between molecules of a different substance. |
| Property | A chemical trait or characteristic of a substance that describes how it looks, behaves, or reacts. |
| Polarity | An uneven distribution of electrical charge in a molecule, which results in a positive and negative side. |
| Transfer | The movement of mater or energy. |
| Energy | The ability to do work or cause change. |
| Atmosphere | The layer of gas surrounding the Earth. |
| Hydrosphere | All water on Earth. |
| Climate | Long term average weather conditions. |
| Convection | The transfer of heat through the movement of fluids. |
| Freeze | To change solid to liquid. |
| Dissolve | To mix evenly into another substance. |
| Specific heat capacity | The amount of matter needed to raise the temperature of a substance. |
| Solid | A state of matter with a definite shape and volume. |
| Liquid | A state of matter with a definite volume but no fixed shape. |
| Gas | A state of matter with no definite shape or volume. |
| Solute | The substance that is dissolved in the solvent. |
| Solvent | The substance that dissolves the solute. |
| Solution | A mixture that forms when a solute dissolves evenly in a solvent. |
| Surface tension | The force at the surface of liquid that acts like stretched skin due to cohesion. |
| Water cycle | The continuous movement of water on, above, and below the surface of the earth. |
| Kelvin scale | A temperature scale that starts at absolute zero and is used mainly in science. |
| Absolute scale | The scale that is used when precise values are needed in comparison to a an unchanging zero point. |
| Universal solvent | A substance that can dissolve many other substances. |
| Homogeneous solution | A mixture that is uniform throughout and has the same composition everywhere. |
| Heterogeneous solution | A mixture that is not uniform and has visibly different parts. |
