CHEMISTRY AS A SCIENCE
What is chemistry? A popular dictionary gives this definition: Chemistry is a science of the composition, structure properties, and reactions of matter, especially of atomic and molecular systems. Another, somewhat simpler dictionary definition is “Chemistry is a science dealing with the composition of matter and the changes in composition that matter undergoes”. Neither of these definitions is entirely adequate. Chemistry is also closely related to biology, not only because living organisms are made of material substances but also because life itself is an essentially complicated system of interrelated chemical processes.
Chemistry’s origin goes back to ancient times, with the manufacture of bronze, iron, ceramics, glass. At the end of the sixteenth century sufficient facts, entirely free of magic which surrounded the work of the alchemists appeared. In the 19th century A. Avogadro introduced the formulation of molecules. He stated that equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules. F. A. Kekule and A. M. Butlerov introduced the structural theory of organic chemistry. In 1869 D. I. Mendeleyev discovered regularities in the properties of the elements. D. I. Mendeleyev’s discovery was the greatest one in chemistry. Many great scientists devoted their life to the development of chemistry among them Bohr whose theory of the hydrogen atom was very important, the Curies who in 1934 announced the preparation of artificially radio-active elements, Marie Curie who discovered radium, and the element polonium.
Everyone now understands the importance of chemistry. The future of chemistry is practically unlimited. Rapid development of chemical industry will make it possible to create many new goods, machines, plastics, polymers, it will help to understand many new phenomena.

8. Подготовьте чтение вслух и переведите письменно следующий текст:
Chemistry is a branch of science that studies the composition and properties of matter and the changes it undergoes. Chemistry is far more than a collection of facts and a body of knowledge. It’s all about matter, which is anything that has mass and occupies space.
Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other.
The etymology of the word “chemistry” has been much disputed. The origin of chemistry can be traced to certain practices, known as alchemy, which had been practiced for several millennia in various parts of the world, particularly the Middle East.
The word chemistry comes from the word alchemy, an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine; it is commonly thought of as the quest to turn lead or another common starting material into gold. An alchemist was called a 'chemist' in popular speech, and later the suffix "-ry" was added to this to describe the art of the chemist as "chemistry".
The definition of chemistry has changed over time, as new discoveries and theories add to the functionality of the science. The term "chymistry", in the view of noted scientist Robert Boyle in 1661, meant the subject of the material principles of mixed bodies. In 1663, "chymistry" meant a scientific art, by which one learns to dissolve bodies, and draw from them the different substances on their composition, and how to unite them again.
The 1730 definition of the word "chemistry" meant the art of resolving mixed, compound, or aggregate bodies into their principles; and of composing such bodies from those principles. The definition further evolved until, in 1947, it came to mean the science of substances: their structure, their properties, and the reactions that change them into other substances. More recently, in 1998, the definition of "chemistry" was broadened to mean the study of matter and the changes it undergoes.

a. Chemistry studies the composition and properties of matter and the changes it undergoes.
b. Alchemy studies the composition and properties of matter and the changes it undergoes.
c. Biology studies the composition and properties of matter and the changes it undergoes.
2. Why is chemistry sometimes called "the central science"?
a. Chemistry is sometimes called "the central science" because it is related to mathematics, physics and astronomy, the fundamental sciences in the world.
b. Chemistry is sometimes called "the central science" because it is the main science in the world.
c. Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other.
3. What did the definition of the word “chemistry” mean in 1730?
a. In 1730 the definition of the word "chemistry" meant the art of resolving mixed, compound, or aggregate bodies into their principles only.
b. The 1730 definition of the word "chemistry" meant the art of resolving mixed, compound, or aggregate bodies into their principles; and of composing such bodies from those principles.
c. In 1730 the definition of the word "chemistry" meant the art of composing the bodies from the principles.
4. How did the definition of “chemistry” change in 1998?

b. In 1998, the definition of "chemistry" was narrowed to mean the study of matter and the changes it undergoes.
c. In 1998, the previous definition of "chemistry" was approved to mean the study of matter and the changes it undergoes
