Looking Into the Future of the Science of Chemistry
The most typical materials now are the products of organic synthesis, the polymers, that is, the various synthetic materials. These materials, produced by chemists in the past few decades, have occupied a very important place in industry, construction and everyday life. This does not mean that natural materials have lost their importance.
Combined with synthetic materials1, they have become even more valuable.
Synthetic plastics have taken the place of metals2 in machine-building and in many respects3 their properties are better than those of metals. Ordinary polymers are better insulators of electricity, and some of them provide the best heat insulation.
Russian scientists discovered that some polymers possessed properties which in some respects are similar to those of iron, although in a much weaker form. So far4 industrial application of some materials has not been reached yet. But further research along such lines may result in5 the development of materials with sufficient electrical conducting and magnetic properties to make them important in automation, electronics and the creation of new types of transistors.

Russian Chemical Science
Since eighteenth century Russia has been one of the leaders in world’s chemistry science and chemical industry. The research and achievements of our scientists have won world-wide recognition. The classical works by D.I. Mendeleyev, A.M. Butlerov, N.D. Zelinsky, S.V. Lebedev, A.E. Favorsky and many others not only served as a theoretical basis for the development of the chemical industry, but enabled Russia to set up a number of modern branches of the chemical industry.
The close links between science and industry enabled the chemical industry to make great progress.
It was in Russia that the large-scale production1 of synthetic rubber was established.
N.D. Zelinsky’s works formed the basis for the synthesizing of a large number of new chemical compounds. There are thousands of them now, and they are extremely important in the economy of our country. Our scientists elaborated a new method of extracting phenol and acetone simultaneously from benzene and propylene. Both these substances are necessary for manufacturing plastics, textile fibres, organic glass and other chemical products.
Together with physicists, our chemists have elaborated an industrial method for manufacturing artificial diamonds which are 40 per cent harder than natural ones.
Many Russian scientists and engineers work at the creation of new polymers which are used in different combinations in order to produce different materials.
Many discoveries Russian chemists made in the field of biology in recent years are forming the basis of new conceptions of matter and will help in creating materials unknown in nature.
The successes achieved by chemistry and engineering have played an important part in our country’s achievements in space.

Age of Chemistry
Chemistry and physics play a very important part in the 21st century. Physicists solve1 many vital problems, but the present great progress in the production of man-made materials is due to chemistry2.
Objects made of natural materials do not possess all the properties required. Man had to use things given by nature. We know three long periods in the history of human progress, named after the basic material used – the stone, the bronze and the iron ages. Now we live in the age of chemistry, which produces synthetic materials.
Due to the great discoveries of the past few decades we are able to go over to a new age3 – the age of synthetic polymers. Chemistry is to remake4 existing materials and create new ones. It is now able to make such wonderful products that very often natural materials have to give way5 to the man-made ones. Synthetic materials will play a still more important part in future.

The States of Matter
That matter may exist in three physical states: solid, liquid or gas is a common knowledge. It is usually possible to change matter from one state to the other by changing its temperature. For instance, a piece of ice is called a solid; it may melt and form a liquid; as it evaporates, liquid water changes into a vapour, i.e. into the gaseous state.
Many kinds of matter, like water, can be obtained in each of the three states; for some, however, extraordinary means have to be used in order to produce one, or even two of the states; and for others, only two states are known or can be produced.
Common salt, for example, exists normally as a solid; at a temperature of several hundred degrees, it can be liquefied; and at still higher temperature it is converted into vapour. Carbon, a solid under normal conditions, can be vaporized, but it has never been liquefied.
Solids have both a definite volume and a definite shape. Liquids too, have a definite volume, but they take the shape of their containers. Gases have neither a definite shape nor a definite volume. A chemist must have a thorough knowledge1 of the states of matter and of the physical laws which govern the behaviour of matter in various states.
That all matter is composed of molecules is known to everybody. The question which must be answered, then, is: if all matter is composed of molecules, what is the essential difference between the states of matter? The answer to this question is that the essential difference between these states is the relative quantities of energy molecules possess in different states.
