Water properties

Capillary Action/Capillarity WATER PROPERTIES Inorganic Universal Solvent Molecule Density Polarity Surface Tension pH Capillary Action/Capillarity Cohesion Adhesion

inorganic = Molecule that does not contain carbon

molecule = Simplest structure composed of elements to make a compound (when two or more elements “stick” together) Hydrogen + hydrogen + oxygen = H20

Polarity =Molecule with both positive and negative charges - unequal

pH = Measure of H+ ions there are

cohesion = When one water droplet is “attracted” to another

adhesion = When water sticks to other surfaces

Capillary action = Allows water and dissolved substances to move throughout an organism against gravity needs the help of cohesion and adhesion

Surface tension = Water clumps together in drops instead of lining up next to one another

density = Mass per unit volume Water expands when frozen which causes it to be less dense & float

Universal solvent = Dissolves more substances than any other liquid because of polarity (charges)
