The Role of Water in Living Organisms Water is one of the most abundant substances on the planet. It can be found naturally in all three states; solid (ice), liquid (water), and gas (steam). However, chemically it is very unusual. For example, water molecules are slightly polar i.e. they have a positive and negative end. Due to this difference in electro-negativity the slightly positive charge on the hydrogen atom is attracted to the slightly negative charge on the oxygen atom in another molecule. This bond is called a hydrogen bond and is what causes the water to have its unusual properties. For example, other molecules of the same size of water (H2O) are all gases at room temperature and pressure (R.T.P). Without the hydrogen bonds, water too would be a gas at RTP and would have a boiling point of -120°C. Because it is polar, water also has uses as a...
