PHXI11:THERMAL PROPERTIES OF MATTER

366606 No other thermometer is as suitable as platinum resistance thermometer to measure temperature in the entire range of

1

0 t o 100^{\circ} C

2

100^{\circ} t o 1500^{\circ} C

3

- 50^{\circ} C t o 350^{\circ} C

4

- 200^{\circ} C t o 600^{\circ} C

366607 On centigrade scale the temperature of a body increased by 30 degrees. The increase in temperature on Fahrenheit scale is

1

54^{\circ}

2

50^{\circ}

3

40^{\circ}

4

30^{\circ}

Explanation:

$\frac{C}{5} = \frac{F - 32}{9}$
$\begin{aligned} \Rightarrow \frac{Δ C}{5} = \frac{Δ F}{9} \Rightarrow Δ F = \frac{9}{5} Δ C \\ Δ F = 54^{\circ} F \end{aligned}$

366608 If a thermometer reads freezing point of water as $20^{\circ} C$ and boiling point as $150^{\circ} C,$ how much thermometer read when the actual temperature is $60^{\circ} C$ ?

1

98^{\circ} C

2

10^{\circ} C

3

40^{\circ} C

4

60^{\circ} C

Explanation:

Temperature on any scale can be converted into other scale by
$\frac{λ - LFP}{UFP - LFP} =$ constant for all scales
$\frac{x - 20}{150 - 20} = \frac{60}{100} \Rightarrow x = 98^{\circ} C$

366609 Which of the following scales of temperature has only positive degrees of temperature?

1 Centigrade

2 Fahrenheit scale

3 Reaumur scale

4 Kelvin scale

366610 Mercury boils at $356^{\circ} C$ . However, mercury thermometers are made such that they can measure temperatures upto $500^{\circ} C$ . This is done by

1 Maintaining vacuum above the mercury column in the stem of the thermometer

2 Filling Nitrogen gas at high pressure above the mercury column

3 Filling Nitrogen gas at low pressure above the mercury column

4 Filling oxygen gas at high pressure above the mercury column
