The Physical Properties of Water

The chemical reactions which water undergoes are so numerous and closely allied to the reactions of many other substances that it is impossible to describe them. We shall become acquainted with many of them afterwards, but at present we shall only cite certain compounds formed by water. Water is a mobile liquid, colorless, transparent, without taste or smell, etc. Its latent heat of vaporization is 534 units, of liquefaction 79 units of heat. The large amount of heat stored up in water vapor,. and also in liquid water, renders it available for heating purposes.
