Waters unique chemical properties and structure allow water to be a
Polar molecule
The positive H in water attracts to the negative O like
weak magnets
Surface Tension is an example of?
Cohesion
In the water Cycle water
Evaporates, form clouds and then fall back to the ground
The Total water on Earth accounts for 97% of
Saline water or oceans
What are the chemical formulas for water, carbon dioxide, oxygen
H2O
CO2
O2
The attraction causes these polar molecules to form temporary bonds that break easily. these bonds are called
Hydrogen Bonds
what allows water to stick to the sides of blood vessels and vascular tubes in plants
Adhesion
