CHAPTER 3 ? WATER AND LIFE THE MOLECUES THAT SUPPORT ALL OF LIFE Water is the only natural substance to exist in all 3 states of matter: Solid Liquid Gas WATER molecule is a polar molecule It has a positive and a negative end It can make up to 4 Hydrogen bonds that break and reform instantaneously. 4 Emergent properties of water COHESION The linking together of like molecules, often by hydrogen bonds. Water sticks to itself Adhesion- water sticks to something else Surface Tension ? A measure of how difficult it is to stretch or break the surface of a liquid. Water has a high surface tension because of the hydrogen bonding of surface molecules MODERATION OF TEMPERATURE BY WATER HEAT AND TEMPERATURE Kinetic Energy ?
