  1. 3. a measure of the acidity or basicity of a solution pure water has a PH of 7 making it neutral
  2. 6. the attraction between molecules of the same substance such as water molecules sticking together
  3. 9. the tightness on the surface of water caused by the cohesive forces between water molecules making the surface act like a stretched elastic sheet
  4. 11. the amount of heat energy required to raise the tempeture of a substance by 1c water high specific heat allows it to stabilize environmental tempatures
  5. 12. the characteristic of a molecule having distinct positive and negative ends, leading to the formation of hydrogen bonds in water
  6. 14. the attraction between molecules of different substances such as water molecules sticking to a glass surface
  7. 16. the mass of a substance per unit volume water is unique because its solid form is less dense than if liquid form

  1. 1. a substance that is dissolved in a solvent for example salt is a solute when dissolved in water
  2. 2. the measure of a fluids resistance to flow water has low viscosity meaning it flows easily compared to move various liquids like honey
  3. 4. 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 mechanisims
  4. 5. the resistance of a substance such as water to changes in temp contributing to te regulation of climate and body temp in organisms
  5. 7. the ability of ice to act as a barrier that slows down the loss if heat from the water beneath it helping to maintain a stable environment for aquatic life during winter
  6. 8. 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. 10. 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. the ability of water to flow in narrow spaces against gravity which occurs due to combination of cohesive and adhesive forces
  9. 15. a homogeneous mixture composed of two or more substances where solute is dissoloved in a solovent such as water
