1. EXEMPLIFY

2. Introduction Scientist use examples to explain or clarify a concept and to give evidence to support it. Examples can sometimes serve to test the validity of a point. If no example can be found to illustrate a point, there may not be a point.

3. Using english to exemplify Each statement is followed by specific examples that serve to illustrate the point. The physical state of a subtance is affected by its temperature. (example makes a point clearer and at the same time, give evidence to support it) For example, at a temperature of C or below, water is a solid . . . Temperature alters the color of matter. (An example may comprise a few words, a sentence, a paragraph or more) Iron for example, turn red, then orange, and then white at increasingly higher temperatures.

4. The size of an object is affected by temperature. (Examples are not always marked with clue words such as for example, for instance, and to illustrate, and often can only be identified by the context of the paragraph.) A glass may break when boiling water is poured into it..... Temperature also affects the pressure of a gas If a closed glass tube is heated, the increased pressure inside will cause it to break.

5. The ability of a metal to resist electricity varies with its temperatures. Heated wires cause excess electricl movement, which can damages machines. Living thinks are very sensitive to comparatively small temperature changes. (sometimes more than one example is used to explain the various aspects of a concept.

6. Exemplifying For example For instance To be specific To illustrate Iron turns red when it is heated For example For instance Iron Turns red when heated An example A case An listance An illustrate Iron is of a substance that turns red when heated

7. Examplifies Illustrates Iron The concept of heat affecting color The concept of heat affecting color is Examplified Illustrated By iron Solids Such as Like iron and copper turn red when heated

8. Note: when writing examples, remember the following • Examples in science are usually written in the present simple tense. • Examples are also used to illustrate terms, and these examples are similar to classification. For intance, the sentence, copper is an example of a metal, is both an example and a classification. If all possible examples of a term are given, it is more classification than example. • Examples are not always marked with clue words and often can only be identified by the context of the paragraph.

9. Modals of Necessity In scientific writting, these modals are used in special ways. Should and mustappear most frequently , usually in the passive voice. Must expresses a very strong need. It implies that anything else is impossible. A speed of 18.000 miles per hour must be maintained for the satelite to remain in orbit. Should is more moderate than must and sometimes expresses a recommendation . The crop should be watered every day during the dry season. However, in thecnical intructions, particularlay for warnings, should is frequently used to mean must. All nonessetential personnel should be evacuated from the area of the explosion. All nonessetential personnel must be evacuated from the area of the explosion.

10. Many times a theory is satisfactory only under limited conditions; a more general theory might be satisfactory without such limitations. For example, the laws of motion discovered by Isaac Newton (1642–1727) in the 17th century accurately describe the motion of bodies at normal speeds but do not apply to objects moving at speeds comparable with the speed of light. • Since Einstein’s discovery of the linkage between space and time, precise measurement of time intervals requires that we know both the state of motion of the clock used to measure the interval and, in some cases, the location of the clock as well. Otherwise, for example, global positioning system satellites might be unable to pinpoint your location with sufficient accuracy, should you need rescuring

11. One mole of substance A contains the same number of particles as there are in 1 mol of any other substance B. For example, 1 mol of aluminum contains the same number of atoms as 1 mol of lead. • Thus, we shall sometimes refer to the order of magnitude of a certain quantity as the power of ten of the number that describes that quantity. If, for example, we say that a quantity increases in value by three orders of magnitude, this means that its value is increased by a factor of 103 _ 1000 • When the zeros come after other digits, however, there is the possibility of misinterpretation. For example, suppose the mass of an object is given as 1 500 g.

12. These rules, which are listed in Appendix B.6, enable us to evaluate derivatives quickly. For instance, one rule tells us that the derivative of any constant is zero. • If an object rotates in the xy plane as in Figure 10.1, the direction of _ is out of the plane of the diagram when the rotation is counterclockwise and into the plane of the diagram when the rotation is clockwise. To illustrate this convention, it is convenient to use the right-hand rule demonstrated in Figure 10.3.
