6. Properties of water Flashcards
1
Q
what is water
A
a polar molecule with a negative charge
2
Q
list the properties of water
A
- Metabolite
- Good solvent
- Large latent heat of vaporisation
- high heat capacity
- cohesive
3
Q
define a metabolite
A
a substance involved in metabolic reactions
4
Q
define a solvent
A
can be attracted and surround ionic compounds allowing them to dissolve into a solution
5
Q
define a large latent heat of vaporisation
A
high boiling point,
6
Q
define a high heat capacity
A
the amount of energy needed to raise the temperature of a 1kg substance by 1 degree celsius
means water does not experience rapid temperature changes
7
Q
define cohesiveness
A
as they are polar they can stick together
meaning easy flows and are able to form collumns
8
Q
define metabolic
A
processes which occur within organisms
