| Question | Answer |
|---|---|
| Water | A polar molecule (H₂O) with unique properties caused by hydrogen bonding. |
| Capillary Action | The upward movement of water in narrow tubes caused by adhesion to surfaces and cohesion between water molecules. |
| Cohesion | The attraction between water molecules due to hydrogen bonds. |
| Adhesion | The attraction between water molecules and other materials or surfaces. |
| Property | A characteristic of a substance that helps describe or identify it. |
| Polarity | When a molecule has uneven charge distribution, creating positive and negative ends. |
| Transfer | The movement of matter or energy from one location to another. |
| Atmosphere | The layers of gases surrounding Earth, important for weather and climate regulation. |
| Hydrosphere | All the water on Earth, including oceans, lakes, rivers, groundwater, and water vapor. |
| Climate | The long-term patterns of temperature, precipitation, and weather in a region. |
| Convection | The transfer of heat by the movement of fluids (liquids or gases) caused by differences in density. |
| Freeze | The process where a liquid loses energy and becomes a solid. |
| Dissolve | When the particles of a solute break apart and spread evenly throughout a solvent. |
| Specific heat capacity | The amount of heat energy needed to raise the temperature of one unit of a substance by one degree. |
| Solid | A state of matter with tightly packed particles that keep a fixed shape and volume |
| Liquid | A state of matter with particles that are close but able to move, giving it a fixed volume but no fixed shape. |
| Gas | A state of matter with widely spaced particles that have no fixed shape or volume. |
| Solute | The substance that is dissolved in a solution. |
| Solvent | The substance that dissolves the solute, forming a solution (water is most common). |
| Solution | A homogeneous mixture where the solute is evenly distributed within the solvent. |
| Surface Tension | The strong “film” on the surface of water caused by cohesive forces between its molecules. |
| Water Cycle | The continuous movement of water through evaporation, condensation, precipitation, and collection. |
| Kelvin Scale | A temperature scale beginning at absolute zero, used in scientific measurement. |
| Absolute Scale | A scale that starts at a true zero point where no thermal energy remains (e.g., Kelvin). |
| Universal Solvent | A term for water because its polarity allows it to dissolve many substances. |
| Homogeneous Solution | A mixture that is uniform throughout, with solute and solvent evenly mixed. |
| Heterogeneous Solution | A mixture where the components are not evenly mixed and can be visibly different. |
| Energy | The ability to cause change or perform work in physical systems. |
