  1. 5. 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. 6. The amount of energy required to convert 1 gram of a liquid into a gas. Water has a high heat of vaporization, which is important in cooling mechanisms like sweating.
  3. 8. A measure of the acidity or basicity of a solution. Pure water has a pH of 7, making it neutral.
  4. 10. The characteristic of a molecule having distinct positive and negative ends, leading to the formation of hydrogen bonds in water.
  5. 11. The attraction between molecules of different substances, such as water molecules sticking to a glass surface.
  6. 13. The attraction between molecules of the same substance, such as water molecules sticking together.
  7. 15. The resistance of a substance, such as water, to changes in temperature, contributing to the regulation of climate and body temperatures in organisms.
  8. 16. A homogeneous mixture composed of 2 or more substances, where a solute is dissolved in a solvent such as salt water.

  1. 1. A substance that can dissolve a wide variety of salutes. Water is known as the universal solvent because it can dissolve more substances than any other liquid.
  2. 2. The ability of water to flow in narrow spaces against gravity, which occurs due to a combination of cohesive and adhesive forces.
  3. 3. 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.
  4. 4. A substance that is dissolved in aa solvent. For example, salt is a solute when dissolved in water.
  5. 7. 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.
  6. 9. 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.
  7. 12. The measure of a fluid's resistance to flow. Water has low viscosity, meaning it flows easily compared to move viscous liquids like honey.
  8. 14. 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.
