Chap 3 – Water and the Fitness of the Environment Objectives 1.Explain why water molecules are polar 2.Explain why they are capable of hydrogen bonding with 4 neighboring water molecules 3.List four characteristics of water that are emergent properties resulting from hydrogen bonding. 4. Define cohesion and adhesion. Explain how this contributes to the movement of water from the roots to the leaves of a tree. 5.Distinguish between heat and temperature. 6.Distinguish among a solute, a solvent, and a solution. 7.Distinguish between hydrophobic and hydrophilic substances 8. Define acid, base, and pH. 9. Explain how buffers work. 10. Briefly explain the causes and effects of acid precipitation and ocean acidification. Key terms acid acid precipitation adhesion aqueous solution base buffer calorie (cal) Celsius scale cohesion dalton electronegativity evaporation evaporative cooling Fahrenheit scale heat heat of vaporization hydration shell hydrogen bond hydrogen ion hydronium ion hydrophilic hydrophobic hydroxide ion Joule (J) kilocalorie (kcal) kinetic energy pH polar molecule solute solution solvent specific heat structural isomer surface tension temperature Outline Water’s Polarity and Its Effects 1. Water is a polar inorganic molecule. Polar molecules have opposite charges at opposite ends. 2. It is the only common substance to exist in three physical states of matter: solid, liquid and gas.
