Because chemical changes.............

Explanation:

........involve the making and breaking of strong chemical bonds, and the formation of new substances. Physical changes do not fall under this umbrella, because while strongish bonds may be broken or formed upon fusion, vaporization, etc., NO new substances are formed. Physical changes are thus largely changes of state.
