Water properties Flashcards
1
Q
Solvent
A
- dipoles
- attract charged particles (ions, polar molecules)
- dissolve in water
- transport medium
- non polar do not dissolve
2
Q
Metabolite
A
- biochemical reactions as reactant
- hydrolysis: splits/reactant
- condensation: product
3
Q
High surface tension
A
- cohesion at surface
- body of insect supported
4
Q
Cohesion
A
- attract eachother
- form hydrogen bonds
- molecules stick together
- lattice
- e.g xylem columns
5
Q
High density
A
- denser than air
- aquatic organisms habitat
- support and buoyancy
- less dense than liquid
- hydrogen bonds hold molecules further apart
- good insulator
6
Q
High latent heat of vaporisation
A
- lots of heat energy
- liquid to vapour
- e.g temp control
7
Q
High specific heat capacity
A
- lots of heat to raise temperature
- hydrogen bonds restrict movement
- resist increase kinetic energy
- stops large fluctuations
