Words and Word-Combinations to Be MemorizedĪlso, angle, atom, atomic, body, check, consist of, correspond, crystal, example, for example, experiment, fact, further, hypothesis (hypotheses), idea, involve, in terms of, law, measure, namely, not only. Thus, by the atomic theory we mean not only the idea that substances consist of atoms, but also all the facts about substances that can be explained and interpreted in terms of atoms and the arguments that explain the properties of substances in terms of their atomic structure. The second use of the word "theory" is to represent a systematic body of knowledge, compounded of facts, laws, theories, deductive arguments and so on. The first meaning of the word is the meaning described above - namely, a hypothesis that has been verified. We find an explanation of the fact in the atomic theory of crystals, the theory that in crystals the atoms are in a regular order.Ĭhemists and other scientists use the word "theory" in two different senses. The law states that whenever we measure the angles between corresponding faces of various crystals of a pure substancc, they will have the same value. For example, there is a law of the constancy of the angles between the faces of crystals. If the hypothesis continues to agree with the results of experiment, we call it a theory or a law.Ī theory, such as the atomic theory, usually involves some idea about the nature of some part of the Universe, a law represents a summarizing statement about observed experimental facts. We can subject it to further tests and to experimental checking of deductions. When we find that an idea explains or correlates a number of facts, we call this idea a hypothesis. We measure weight by grams, kilograms, tons, etc. The director ordered him to come at once. In crystals the atoms arc in a regular order. They parted in 1985 when she went to Moscow. This part of the work is the most difficult one. When you arc not sure that your result is right, check it up. When we want to learn more about a substance, we subject it to study.ħ. Chemistry is a very interesting subject.Ħ. There are various means of getting substances. Experimentally means during the experiment. Define what parts of speech the italicized words belong to.ġ.
