IMPORTANCE OF WATER
Properties of Water =
Cohesion
Adhesion
High Specific Heat Capacity
Polar Solvent
Cohesion =
When 2 water molecules stick together, due to the hydrogen bonds, this enables
water to flow.
IMPORTANT OF COHESION –
Allows water to move up the xylem in transcription.
Allows the transport molecules in plants and animals.
Gives water a high surface tension.
Adhesion =
Water molecules attracted to different polar substances.
IMPORTANCE OF ADHESION –
Allows water to move up a plant in the xylem.
Allows polar substances to dissolve in water.
Allows for capillary action.
High Specific Heat Capacity =
All those hydrogen bonds within water are great at absorbing energy, meaning
water therefore requires a lot of heating in order to increase its temperature.
Water requires lots of energy to increase temperature.
Polar Solvent =
Great solvent – tiny charges [DELTA MINUS/PLUS] in its molecules attract other
molecules in effect dissolving them.
Water is a good solvent because it has polar properties, it can form hydrogen
bonds with other charged on other polar molecules, which can dissolve in water.
IMPORTANCE OF POLAR SOLVENT –
Solubility
