Across
- 4. bond a weak bond between two molecules, where a hydrogen atom in one molecule is attracted to an electronegative atom in another molecule, common in water molecules
- 6. the mass of a substance per unit volume. water is unique because its solid form (ice)is less dense than its liquid form, allowing ice to float
- 9. tension the tightness on the surface of water caused by the cohesive forces between water molecules, making the surface act like a stretched elastic sheet
- 12. the ability of ice to act as a barrier that slows down the loss of heat from water beneath it, helping to maintain a stable environment for aquatic life during winter.
- 13. of vaporization the amount of energy required to convert 1 gram of a liquid into a gas. water has a high heat vaporization, which is important in cooling mechanisms like sweating
- 14. the measure of a fluids resistance to flow. water has low viscosity, meaning it flows easily compared to more viscous liquids like honey
- 15. the attraction between molecules of different substances, such as water molecules sticking to a glass surface
Down
- 1. a substance that is dissolved in a solvent. For example, salt is a solute when dissolved in water.
- 2. the characteristic of a molecule having distinct positive and negative ends, leading to the formation of hydrogen bonds in water
- 3. A measure of the activity or basicity of a solution. pure water has a pH of 7, making it neutral
- 5. solvent a substance that can dissolve a wide variety of solutes. water is known as the universal solvent because it can dissolve more substances than any other liquid
- 7. stability the resistance of a substance , such as water, to changes in temperature, contributing to the regulation of climate and body temperature in organisms
- 8. Action the ability of water to flow in narrow spaces against gravity, which occurs due to a combination of cohesive and adhesive forces
- 9. a homogeneous mixture composed of two or more substances , where a solute is dissolved in a solvent, such as saltwater's
- 10. the attraction between molecules of the same substance, such as water molecules sticking together
- 11. heat the amount of heat energy required to raise the temperature of a substance by 1^c waters high specific heat allows it to stabilize environmental temperatures
