Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
Heat of vaporization of water will be required as water is already at it's boiling point thus heat required will be 540*10=5400 cal
Precipitation tends to be HIGHER on the WINDWARD SIDE of the a mountain because water vapour CONDENSES as it rises there.
There are two sides to every mountain, the windward and the leeward sides. The windward side experience more rainfall while the leeward side is drier and warmer.
