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.
