## Calorimetry Exercise 233

### Solution 1

### Solution 2

### Solution 3

### Solution 4

### Solution 5

The SI unit of heat energy is joule (J).

### Solution 6

^{o}C.

### Solution 7

1 J = 4.2 cal. So, 1 joule is bigger than 1 calorie.

### Solution 8

### Solution 9

### Solution 10

### Solution 11

### Solution 12

### Solution 13

i. Celsius scale

ii. Fahrenheit scale

### Solution 14

### Solution 15

### Solution 16

### Solution 17

^{o}C and boiling point of water as 100

^{o}C. The same points on the Fahrenheit scale are 32

^{o}F and 212

^{o}F.

### Solution 18

^{o}C.

### Solution 19

### Solution 20

^{o}F

Upper fixed point = 212

^{o}F

### Solution 21

^{o}C). Thus, the melting point of ice is taken as 0

^{o}C and the boiling point as 100

^{o}C.

### Solution 22

### Solution 23

### Solution 24

## Calorimetry Exercise 234

### Solution 25

### Solution 26

^{o}C (or -459.4

^{o}F).

### Solution 27

### Solution 28

### Solution 29

SI unit of:

i. Amount of heat - joule

ii. Heat Capacity - joule per Kelvin

iii. Specific Heat Capacity - joule per kilogram per Kelvin

### Solution 30

### Solution 31

### Solution 32

^{-1}K

^{-1}.

### Solution 33

### Solution 34

(i) In cooling - Water is used in the cooling systems of automobiles and other engines.

(ii) As heat reservoir - In cold countries, water is used as a reservoir for wine and juice to avoid their freezing. The reason is that water can provide more heat to the bottles due to its high specific heat capacity. Hence, they do not cool down further to freeze.

### Solution 35

It is made of copper because:

i. Copper is a good conductor of heat so it attains the temperature of its contents in a very short time.

ii. It has low specific heat (390 Jkg

^{-1}K

^{-1}). Therefore, it will take only a very little part of the heat energy given out in the experiment.

### Solution 36

### Solution 37

^{0}C, then the veins of the plants shall freeze. Due to anomalous expansion of water, ice shall occupy more volume than water. As a result of this expansion, veins shall burst and crops shall be destroyed. But water sprinkled on the crops shall not allow the temperature of the veins to fall below 0

^{0}C.

### Solution 38

### Solution 39

Heat capacity of a body is the quantity of heat required to raise its temperature by 1^{o}C. It depends upon the mass and the nature of the body.

Units: J/^{o}C or calorie/^{o}C

### Solution 40

Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of the substance by 1^{o}C.

Units: j/kgK or calorie/g ^{o}C

### Solution 41

### Solution 42

### Solution 43

^{-1}K

^{-1}) is about five times as that of sand. Due to which water takes long time to get heated up and equally long time to get cooled. Thus, large temperature difference between the land and the sea causes formation of land and sea breezes.

### Solution 44

When a hot body is mixed or kept in contact with a cold body, there is a transfer of heat from hot body to cold body such that

Total heat gained by colder body = Total heat lost by the hot body,

if there is no loss of heat to the surroundings.

### Solution 45
