Document Summary
Tendency of water molecules to stick to one another: ability to moderate temperature. High specific heat in water, water is able to absorb high amounts of heat before rising in temperature. Sweating through evaporative cooling to keep us cool: expansion upon freezing. As water becomes a solid, it is less dense than a liquid. When a liquid, the hydrogen bonds are constantly breaking and reforming thus making it a liquid. Essential to life because all the oceans and lakes would be frozen ice rather than having ice float: versatility as solvent. Solutes we depend on are from water acting as a solvent. Temperature: measures the intensity of heat due to average ke of molecules regardless of volume. Water high specific heat: amount of heat that must be absorbed to change temperature by 1 degree. The high specific heat is due to its hydrogen bonding. Evaporative cooling: helps stabilize temperatures in organism and bodies of water.
