PHYSICAL AND CHEMICAL CHANGESTransformations are of two kinds, known as physical and chemical changes.Physical changes are those which effect the state or condition of matter withoutchanging its composition. There is no change in the composition of a substancewhen it is transformed from the liquid to the gaseous state by heating, or from theliquid to the solid state by cooling, and vice versa. Thus, in all three states, stream,water, and ice are all the same substance, made up of the simpler substances,hydrogen and oxygen. The state, but not the composition is effected by the process ofheating or cooling.By changes in the conditions of a substance are meant changes such as when asolid mass is made to fine powder, salt or sugar are dissolved in water. It is clear thatsuch transformations like the changes from one state of matter to another, do notaffect the composition of the material. The fine power of a substance may be madesolid again, and we get back the sail or sugar unchanged by evaporating the water.Chemical changes, however, are those matter changes in which changes ofcomposition does take place and the new substance formed will not return to itsoriginal state, unless it is subjected to another chemical change. Thus iron, when it iseffected by moist a ir, is slowly transformed into iron rust entirely different in itsproperties from the original iron. The new substances will not become iron againwhen it is allowed to stand, although the iron can be obtained from it if it issubjected to the proper conditions
