1
What does it mean by water molecules being polar?
This means that water has partial postive and negative charges
2
What parts of water molecule are what charges?
3
Where do hydrogen bonds form in water molecules?
Between the postive H and Negative O
4
What are the 5 properties of water?
-It is a metabolite
-It is a solvent
-It has a high specific heat capacity
-It has a high latent heat of vaporisation
-It has cohesive forces between water and molecules
-It is a solvent
-It has a high specific heat capacity
-It has a high latent heat of vaporisation
-It has cohesive forces between water and molecules
5
What does being a metabolite mean?
A substance necessary for or taking part in a particular metabolic process
6
Why is water a metabolite?
It is used in hydrolysis reactions and is a product of condensation reaction
7
Why is it important that water is a solvent?
Substances can dissolve in water allowing metabolic reactions to occur and substances to be transported
8
Why is it important that water has a High specifc heat capacity?
So it buffers (resists) changes in temperature
9
Why is it important that water has a High latent heat of vaporisation?
Evaporation of water exerts a cooling effect on organims
10
What 2 reasons are there for water having cohesive forces between water molecules?
-Suports water colums in the xylem
-Creates surface tension so supports organims
-Creates surface tension so supports organims
