C ANSWERS TO QUESTIONS GIVEN IN TEST 7)
13(a) Point out the difference between "heat” and
"temperature”.
"Heat" is a form of energy which, when supplied to a body, will cause one or more of the followin changea:--
1. raise its temperature; 2. affect its volume. 3. change ite state.
"Temperature" is the degree of hotness of a body. To point out the difference between these two terms more clearly, heat a small iron nail by a bunsen hurner for 2 minutes, and a lump of iron weighing about 1. lh, by the same bunsen burner for the same time. Afterwards, the nail becomes red hot, but the lump of iron is only quite warm. The amount of heat supplied by the bunsen burner in each case is the same, but the nail rises to a higher temperature than the large lump of iron, This showe that the two terma "heat and "temperature are not the same.
(b) What is the temperature at which the Centigrade
scale is 5 timeg the Fahrenheit scale?
Let x. and 5x°C. be the required temperature. By the formula F. = 20+ 32.
we have
Y X =
8x
539* 32 = 9x + 32]
=-321
-4.
器 =

The temperature required is -4°F. or -20°c.
(o) Mention the advantages and disadvantages of using
mercury as the liquid in thermometers.
The advantages are;--
1. Mercury is opaque;
2. mercury is a good con-
ductor of heat; 3. mercury expands regularly;
4. mercury has a high boiling point (357°c.) and
a fairly low freezing point (-39°c.);
has low specific heat;
the glass tube,
5, mercury
6. mercury does not wet -
The disadvantages are:---
1. Mercury has a low coefficient of expansion (0.00018); 2. mercury is heavy.
(d) Describe the construction and use of a thermometer
which can give the maximum and minimum temperatures. This kind of thermometer is called
MAX.
a Sixers Thermometer. On top of the left-hand tube the bulb containe

alcohol, whose expansion and con- traction decide the temperatures. Alcohol Underneath, there is a column of mercury, which filla the tube of very narrow bore.
F. F
·Alschali
INDEX
INDS
On top of the
right-hand tube there is a littlo alcohol. In the space above the alcohol, air has been removed, and it is filled with alcohol vapour.
When the aiconor in the left-hand tube expands, it pushes the mercury thread, and the mercury pushes the right-hand index, which is in the klcohol. When it gets cold, the alcohol in the left-hand bulb con- tracts, the pressure of alcohol vapour in the right-hand tube pushes, the mercury back, and the mercury thread in turn the left-hand index
Marowy
Both indexes cannot move down unless they are being pulled down with a augnet, so the right- hand index indicates the maximum temperature, and the left-hand one, the minimum To set the thermometers, mugnets are used to pull the indexes down, until they touch the mercury
Notice that the mercury sur- surfaces again. faces at both ends must point to the same temperature, which ia_the_temperature at the, time or reading./
(a) Explain why the coefficient of superficial1
expansion of a substance is equal to twice that of the coefficient of linear expansion. Let the length of a square plate be 1 inch: Let the coefficient of linear expansion be a. the new length When the temperature rises 1° will be (1a) inoh. The new area will be (1 − a) (1 + aj aq. in.,}
or( T + 2a + a) eg,怎么。
•
a is a very small quantity, usually with 40le after the decimal point, eo an will have 8 0 s after the decimal point. This quantity ie eo. small that it can be neglected.
We may say now that the new area is (1.+ 28)) eq. in.
Coefficient of superficial expansion'
Increase in area
缀
Original area x rise of temperature
= 28.
Therefore, the coefficient of superficial
expansion is twice the coefficient of linear expansion.
(b) what is the ratio of the densities of copper'
at 10c. and 50°C.?
Coefficient of linear expansion of copper
= 0.000017.
Coefficient of cubical expansion of copper)
= 0.000017 x 3 = 0.000051.
Density at 50°c.
Deneity at 50°C.=
Density at 1090.
0.0000313 40
Density at 10°C.
1.00204
Therefore the density at 10°C. density at 50°c.) = 1.00204 : 1.
(c) Clve three practical uses of compound bars.?
The three uses are:--

1. Compound rulers of iron and brase rode of
lengths 3 feet and 2 feet can give accurate
| length of 1 foot (the difference between
.their lengths) at any temperature as long
as these metain are in solid form.
2. The compensated pendulum can be made with inon
and, brass bars to keep the length of the pendulum constant at any temperature.
3. A fire alarm can be made with a compound bar
of iron and,copper connected to an electric bell.
{d} A cube of glass whose sides are exactlyof cm.
long at 30°c. is immersed in water at 4°C.; what is the upthrust of water on the glass, after it has come to the same temperature as, the water?.

QUESTIONS ON HEAT.
15. (a) Distinguish between "apparent expansion" and
"real expansion" of liquids. (b) Describe the abnormal expansion of water.
Show, by Rope's Apparatus, that water has its maximum density at 4°C. Why is this experiment usually not successively carried out in Hong Kong in summer?
