I. Water is Polar • Water is slightly charged on either end.

II. Water is a Universal Solvent • Solvent – Substance that does the dissolving. • Solute – Substance that gets dissolved. • More things dissolve in water than anything else. This is important because many chemical reactions only occur when the reactants are dissolved.

III. Water has a high specific heat • It takes a lot of energy to raise 1 gram of water by 1˚C. This means water heats up and cools down slowly.

IV. Water is less dense as a solid • Water expands when it freezes. This is why ice floats.

V. Water is Cohesive • Water sticks to itself.

Cohesion is important to…. • Water Striders! • This creates surface tension, allowing water striders to “walk on water”.

VI. Water is Adhesive • Water sticks to other objects. • Capillary action is when water sticks to small tubes and climbs up against the force of gravity.

Adhesion is important to… • Plants! This is how they get water from their roots to their leaves. Xylem tubes in a tree Redwood trees – 350 feet tall
