What gives water is polarity
Negative oxygen and positive hydrogen
What bonds does water have
weak hydrogen bonds
Why is water being a metabolite important
For hydrolysis and condensation reactions
Why is water being a good solvent important
Polar molecules can dissolve in water allowing easy transportation
Why is waters high heat capacity important
Regulates temperature
Why is waters high latent heat of vaporisation important
It allows water in sweat to remove heat and cool people down
Why do hydrogen bonds aid heat capacity and latent heat
They require a lot of energy to break
Why is waters cohesive nature important
It allows molecules to stick together due to H+ bonds providing surface tension
Name 5 features of water
High specific heat capacity and latent heat of vaporisation, metabolite, solvent and polar
Describe how density decreasing with temperature so ice floats, aids ponds and their organisms
Molecules are more spread out forming a lattice, the insulating ice layer prevents water below from freezing allow organisms to move and nutrient to circulate
Describe how a pond’s water acting as a solvent for ions like nitrates, aids organisms’ survival
Ions are polar and can bind to water to enter the organism, nitrates can then be used in proteins and nucleic acids
Describe how a large quantity of energy required to raise the pond’s temp by 1degree, aids the organisms in the pond
Many stable hydrogen bonds require lots of energy to break, giving a high SHC, so temperature variates less, not effecting enzymes and rate of reaction
