2. Read the sentences below and choose the correct word. Then read the
text and check if your guesses were correct.
a) Temperature is an absolute / relative measure of hotness or coldness.
b) If the temperature of a substance increases, the motion of its molecules
becomes faster / slower.
c) Temperature is measured accurately through the sense of touch / use of a
thermometer.
d) Mercury which usually fills a glass tube of a thermometer is coloured with a
red dye to make it beautiful / visible.
e) A degree Celsius almost is twice as large / twice as small as a degree
Fahrenheit.
3. You are going to read the text. Six sentences have been removed from it.
Choose from the sentences A F the one which fits each gap (1-6).
A. Centigrade (cent one hundred (as in century) and grade, German for
degree) referred to the 100 degrees between the ice and steam points.
B. It expands on heating, and a column of liquid is forced up the capillary tube.
C. This perception is unreliable and may vary a great deal for different people.
D. We simply add 273 to the Celsius temperature.
E. The molecules of all substances are in constant motion.
F. Common names for the ice and steam points are freezing and boiling points
respectively.
Temperature tells us whether something is hot or cold. In fact, we can say
that temperature is a relative measure of hotness or coldness.
On the molecular level we find that temperature depends on the kinetic
energy of the molecules of a substance.
1 E
The observation is true even for solids in which the molecules are held together
by intermolecular forces. In general, the greater the temperature of a substance,
the greater the motion of its molecules. On this basis we say that temperature is
a measure of the average kinetic energy of the molecules of a substance.
Humans have temperature perception in the sense of touch. Our
sense of touch doesnt allow us to measure temperature accurately. 2
The quantitative measurement of temperature is accomplished through the
use of a thermometer, an instrument designed to measure temperature. There are
many kinds of thermometers but their operation always depends on some
property of matter that changes with temperature. It is thermal expansion.
Nearly all substances expand with increasing and contract with decreasing
temperature. Common thermometers today consist of a hollow glass tube filled
