Water Properties Notes 

- Oxygen is extremely electronegative = hogs electrons 

- hydrogen bond= key for water flowing past itself, take in heat and regulate temperature 

- water is a polar molecule because of its polar covalent bonds and its shape 

- NON POLAR molecules like fats and oils and they will not react well with water 

- POLAR= adhesion 

- COHESION= water being attracted to itself 

- SURFACE TENSION is due to the cohesion of the water and breaking of the bonds due to kinetic energy 

- Things that dissolve in water are HYDROPHILLIC

- Stuff that does not dissolve in water are NONPOLAR AND HYDROPHOBIC 

- Higher the kinetic energy= broken hydrogen bonds= water into gas 

- Little kinetic energy, drop in temp= strong hydrogen bonding= water into ice 

- Ice is less dense than water due to the water molecules being pushed farther apart than water's liquid state 

    -water expands when it freezes 

- Water has a high boiling point due to its hydrogen bonding
