  1. 3. the characteristics of a molecule having distinct positive and negative ends, leading to the formation off hydrogen bonds in water.
  2. 4. 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.
  3. 7. Action The ability of water to flow in narrow spaces against gravity, which occurs due to a combination of cohesive and adhesive forces.
  4. 10. 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.
  5. 11. A measure of the acidity or basically of a solution. Pure water has a PH of 7, making it neutral.
  6. 13. The measure of a fluid's resistance to flow. Water has low viscosity, meaning it flows easily compared to more viscous liquids like honey.
  7. 14. The ability of ice to act as a barrier that slows down the loss of heat from the water beneath it, helping to maintain a stable environment for aquatic life during winter.
  8. 16. Stability The resistance of a substance, such as water, to changes in temperature, contributing to the regulation of climate and body temperature in organisms.

  1. 1. 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.
  2. 2. The attraction between molecules of the same substance, such as water molecules sticking together.
  3. 5. A homogeneous mixture compound of two or more substances, where a solute is dissolved in a solvent, such as saltwater.
  4. 6. The attraction between molecules of different substances, such as water sticking to a glass surface.
  5. 8. Heat The amount of heat energy required to raise the temperature of a substance by 1ºC. Water's high specific heat allows it to stabilize environmental temperatures.
  6. 9. A substance that is dissolved in a solvent. For example, salt is a solute when dissolved in water.
  7. 12. of Vaporization The amount of energy required to convert 1 gram of liquid into a gas. Water has a high heat of vaporization, which is important in cooling mechanisms like sweating.
  8. 15. Solvent A substance that can dissolve a wide variety of solutes. Water is known as the universal solvent because it can dissolve mor substances than any other liquid.
