When newly made steel is first exposed to the air, its originally shiny surface will be covered with rust in a few hours. The tendency of metals to corrode is related to the low stability of the metallic state. Metals occur either in the pure metallic state, the zero oxidation state, or in the form of compounds with other elements (they acquire positive states of oxidation)...

Water If water followed the example of other molecules its size it would have a boiling point of -75oC and a freezing point of -125oC4. This would mean that, on Earth, water would be a gas all of the time and life would not be possible...	3 / 592
The polarity of water Evaporative cooling is based on water’s high heat of vaporization. Water molecules must have a relatively high kinetic energy to break hydrogen bonds. The evaporative loss of these energetic water molecules cools a surface...	3 / 652
