what are the 4 functions of water
metabolite
solvent
cohesive
helps with control of temp
What is the structure of water
H2O
Polar molecule - slight negative and slight positive
these attract to each other and the attraction is called hydrogen bonding
Why does water have the ability for any of its functions
The attraction of hydrogen bonding gives water useful properties
Why is water a good solvent
A lot of important substances in metabolic reactions are ionic e.g salt and because water is polar it will attract negative ions and postive and surround them - they'll dissolve
Why can water resist temperature changes
The hydrogen bonds between water molecules absort alot of energy
How is water cohesive
They are cohesive(stick together) because they're polar
What are two advantages of waters strong cohesion
Its means that water has a high surface tension
It helps water to flow making it useful for transporting substances
