Document Summary
Polarity: covalent bonding (sharing of electrons) between oxygen and hydrogen. Molecule is positively charged on one end, negatively charged on the other. Hydrogen bonding: due to attraction of the positive and negative ends of. Present in all 3 phases in earth"s temperature range. Large quantities of heat are required to raise temperature (~4 j to raise 1g by 1 degrees celsius) Higher heat capacity than that of any solid or liquid other than ammonia. Ocean water temperatures are relatively stable compared to terrestrial temperatures. Energy required to bring 1g of liquid h2o from boiling point to boiling is the greatest. Massive quantities of heat required to vaporize liquid water. Key factor in atmospheric heat transport and in hurricane formation. Higher latent heat of vaporization than that of any other substance. Heat is transported from the low-latitude ocean by evaporation and atmospheric circulation and released to the atmosphere through precipitation at higher altitudes. Is an effective solvent due to its polarity.
