Document Summary
Viscosity: measure of resistance to low, velocity is 0 at bank. When it enters stream, velocity increases: viscosity - any luid resists low. Water is universal solvent: important for moving material, dissolving many materials, covalent bonds, hydrogen bonds, polarity, low viscosity, surface tension - universal solvent. No - oil has no charge (non polar) Water and life: photosynthesis and respiration: carbon dioxide and energy (sun) - to sugar molecules and water and oxygen, carbon has been taken from inorganic space through processes of photosynthesis and transferred into organic form. Water and life: major biogeochemical processes res on water - enable cell structure, function, and division, carry food, oxygen, remove waste. Would life exist on this planet without water: in terms of temp(x) pressure(y) diagram, phase diagrams. Thermal properties of water: compared to others liquids, water has a large liquid range, liquid can exist up to 343c at deep sea vents, if add salt, then can lower freezing point to -45c.
