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