Across
  1. 2. possible due to the fact that lots of heat is needed to break hydrogen bonds between water molecules covering some objects
  2. 3. force which results from hydrogen bonds in water resist to pressure of the submerged object; it allows for floating
  3. 7. the process which makes dissolved substances spread in water
  4. 10. property of water which lets light through
  5. 12. turning liquid water into solid state
  6. 14. substances which form hydrogen bonds with water and attract water molecules due to that
  7. 16. diffusion of water molecules through the semi-permeable membrane
  8. 17. substance which has no polar groups so it does not attract water
  9. 19. created at the water surface due to presence of hydrogen bonds between water molecules
Down
  1. 1. force which water molecules stick to solid surfaces made of hydrophilic substances
  2. 4. the substance which can easily dissolve in water and enable respiration of aquatic organisms
  3. 5. substances which have domains attracting water as well as repelling it
  4. 6. type of movement of water possible due to the fact that it is liquid in some temperature range
  5. 8. floats on water tanks in winter insulating lower layers of water from freezing to the bottom
  6. 9. a chemical reaction in the organism for which a water molecule is necessary
  7. 11. force which makes water molecules stick to each other due to hydrogen bond formation
  8. 13. body fluid which can transport variety of substances due to water being a good solvent
  9. 15. water is this for variety of polar substances but not for lipids
  10. 18. the process which converts masses of liquid water into water vapour
