Water
Water Chemical Formula H 2 O H 2 O 2 Hydrogen Atoms 2 Hydrogen Atoms 1 Oxygen Atom 1 Oxygen Atom
Ways water is unique Polar Molecule Surface Tension Capillary Action
Ways water is unique Change in State Universal Solvent
Polar Molecule A molecule that has electrically charged areas
Polar Molecule Oxygen= negative Hydrogen= positive
Polar Molecule Many billions of water molecules Arrangement of water molecules A water molecule
Polar Molecule Positive Hydrogen ends of 1 water molecule attract the negative oxygen ends of another water molecule Water Molecules stick together (COHESION)
Surface Tension Tightness across the surface of water Caused by the polar molecules pulling on one another
Surface Tension Causes the surface of water to be curved shape
Capillary Action Demonstration
Capillary Action The combined force of attraction between water molecules with the molecules of surrounding materials
Capillary Action Causes the water inside a straw to rise higher than the water outside the straw Causes water to move up a string or paper
Change in State Water is the only substance on Earth that commonly exists in all of its different states!!!!
Universal Solvent Water is able to dissolve many substances because it is polar The charged ends of the water molecule attract the molecules of other polar substances (ADHESION)
