Properties of Water (Cohesion, Adhesion, Capillary Action, Surface Tension, Density, Solvent)

heat capacity

Water

Density

Water has a high density

Adhesion

Attraction between molecules of different substances

Cohesion

Attraction between molecules of the same substance

Solvent

Water is a universal solvent. Substances that dissolve in water are hydro-philic, and those that don't are hydro-phobic.

bases

pH greater than 7, increase the concentration of OH- ions when dissolved in water.

acids

pH less than 7, increase the concentration of H+ ions when dissolved in water.

Surface Tension

A measure of how difficult it is to stretch or break the surface of a liquid

polarity

A molecule that has a slight positive charge on one side and a slight negative charge on the other. (Water)

Capillary Action

A proccess powered by adhesion that causes water molecules to move upward through a narrow tube such as the stem of a plant.
