  1. 3. Dynamics The study of how fluids move, which includes understanding viscosity and flow rates.
  2. 4. The level of base in a substance. Substances with a pH greater than 7 are basic or alkaline.
  3. 6. The attraction between molecules of the same substance, such as water molecules sticking together.
  4. 8. The attraction between molecules of different substances, such as water molecules sticking to a glass surface.
  5. 9. Heat The amount of heat energy required to raise the temperature of a substance by 1°C. Water's high specific heat allows it to stabilize environmental temperatures.
  6. 12. 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.
  7. 14. 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.
  8. 15. Regulation The ability of a substance to maintain a stable temperature, important for environments and living organisms.

  1. 1. The characteristic of a molecule having distinct positive and negative ends, leading to the formation of hydrogen bonds in water.
  2. 2. 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.
  3. 5. Forces The intermolecular forces that cause different molecules to stick together. This helps water climb up surfaces.
  4. 7. The process by which solvent molecules surround and interact with solute molecules, leading to dissolution.
  5. 8. The level of acid in a substance. Measured on the pH scale, substances with a pH less than 7 are acidic.
  6. 10. Forces The intermolecular forces that cause similar molecules to stick together. In water, this results in surface tension.
  7. 11. 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.
  8. 13. of Vaporization 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.
