Water A really strange molecule

Water (H2O) has some very strange chemical and physical properties. It can exist in all three states of matter at the same time. Imagine that you re sitting in your hot tub (filled with liquid water) watching the steam (gas) rise from the surface as you enjoy a cold drink from a glass filled with ice (solid) cubes. Very few other chemical substances can exist in all these physical states in this close of a temperature range. 

Another unique property of water is its ability to dissolve a large variety of chemical substances. It dissolves salts and other ionic compounds, as well as polar covalent compounds such as alcohols and organic acids. In fact, water is sometimes called the universal solvent because it can dissolve so many things. It can also absorb a large amount of heat, which allows large bodies of water to help moderate the temperature on earth. 

Intermolecular forces can be of three different tjq es. The first t5q e is called a London force or dispersion force. This very weak type of attraction generally occurs between nonpolar covalent molecules, such as nitrogen (Nj), hydrogen (H ), or methane (CE ). It results from the ebb and flow of the electron orbitals, giving a very wesik and very brief charge separation around the bond. 

The second tjq e of intermolecular force is called a dipole-dipole interaction. This intermolecular force occurs when the positive end of one dipole molecule is attracted to the negative end of another dipole molecule. It s much stronger than a London force, but it s still pretty weak.
