Dihydrogen Monoxide

1. Dihydrogen Monoxide http://www.dhmo.org/

2. This molecule has a high surface tension. In other words, dihydrogen monoxide is adhesive and elastic, and tends to aggregate in drops rather than spread out over a surface as a thin film. This phenomenon also causes this molecule to stick to the sides of vertical structures despite gravity's downward pull. It’s high surface tension allows for the formation of droplets and waves, allows plants to move this molecule (and dissolved nutrients) from their roots to their leaves, and the movement of blood through tiny vessels in the bodies of some animals. Adhesion and Cohesion

3. Adhesion—sticks to other stuff • Cohesion—sticks to self • Surface tension—ability of a substance to stick to itself

4. This molecule is a universal solvent. It is able to dissolve a large number of different chemical compounds. This feature also enables this molecule to carry solvent nutrients in runoff, infiltration, groundwater flow, and living organisms. • We can use it to clean because it dissolves most everything. Universal Solvent

5. This molecule is neither acidic (like lemon juice, sour candy, or vinegar) nor basic (like antacids, baking soda, or ammonia) pH—neutral

6. Phase changes

7. Water molecules exist in liquid form over an important range of temperature from 0 - 100° Celsius. This range allows water molecules to exist as a liquid in most places on our planet. Dihydrogen monoxide=water

8. Because of it unique physical and chemical properties, water is easily polluted. Water pollution
