Scientists use examples to explain concepts, provide evidence to support points, and test the validity of arguments. Examples clarify statements and illustrate various aspects of concepts. For instance, iron turns red at increasingly higher temperatures, exemplifying how heat affects the color of matter. Living things are also very sensitive to small temperature changes. Examples in science are usually written in the present simple tense and can identify terms through classification.

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 𝟎°
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.

8. Note: when writing examples, remember the following
1. Examples in science are usually written in the present simple tense.
2. 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.
3. 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.
