Which thermometer is the best for measuring rapidly-changing temperatures?
- A.
A thermocouple
- B.
A liquid-in-glass thermometer
- C.
A clinical thermometer
- D.
All thermometers are equally good
Correct Answer
A. A thermocoupleExplanation
A thermocouple is the best thermometer for measuring rapidly-changing temperatures because it is highly responsive and can quickly detect and measure temperature changes. Unlike other types of thermometers, such as a liquid-in-glass thermometer or a clinical thermometer, a thermocouple uses two different metals to generate a voltage that is proportional to the temperature difference between the two junctions. This allows for fast and accurate measurements of rapidly-changing temperatures.Rate this question:

- B.
A
- C.
B
- D.
D
Correct Answer
A. CExplanation
Decreasing the volume of liquid and increasing the diameter of the bore of the thermometer will produce the greatest increase in sensitivity. This is because a smaller volume of liquid will be more responsive to temperature changes, and a larger diameter of the bore will allow for better heat transfer between the liquid and the thermometer, increasing the sensitivity of the thermometer.Rate this question:

A thermocouple thermometer uses a voltmeter to measure the e.m.f. generated between two junctions. The junctions are at temperatures t1 and t2. To calibrate the thermometer, fixed points are needed.What are the values of t1 and t2 when the thermometer is calibrated at the steam point? t1 t2 A B C D 0 0C 0 0C 25 0C 25 0C 0 0C 100 0C 0 0C 125 0C
- A.
B
- B.
A
- C.
C
- D.
D
Correct Answer
A. BExplanation
The correct answer is B. In order to calibrate the thermometer at the steam point, the values of t1 and t2 should be 0°C and 100°C respectively. This is because the steam point is defined as the temperature at which water boils, which is 100°C at standard atmospheric pressure. Therefore, t1 should be 0°C (the freezing point of water) and t2 should be 100°C (the boiling point of water).Rate this question:

What makes a liquid-in-glass thermometer sensitive to a small change of temperature?
- A.
A bulb with a thin glass wall
- B.
A shiny liquid in its bore
- C.
A stem with a thick glass wall
- D.
A very narrow bore
Correct Answer
D. A very narrow boreExplanation
A liquid-in-glass thermometer is sensitive to a small change of temperature because of its very narrow bore. The narrow bore restricts the flow of the liquid, causing it to expand or contract more easily in response to temperature changes. This allows for a more precise measurement of temperature as even a small change in temperature will result in a noticeable change in the liquid level within the narrow bore.Rate this question:

To calibrate a thermometer, without using another thermometer, fixed points are required. Which statement is correct?
- A.
Both a lower fixed point and an upper fixed point are required.
- B.
Any temperatures can be used as fixed points.
- C.
Only a lower fixed point is required.
- D.
Only an upper fixed point is required.
Correct Answer
A. Both a lower fixed point and an upper fixed point are required.Explanation
To calibrate a thermometer, both a lower fixed point and an upper fixed point are required. This is because a lower fixed point, such as the freezing point of water, provides a reference for the lowest temperature that the thermometer can accurately measure. Similarly, an upper fixed point, such as the boiling point of water, provides a reference for the highest temperature that the thermometer can accurately measure. By calibrating the thermometer using these two fixed points, the accuracy and reliability of temperature measurements can be ensured across the entire temperature range.Rate this question:

The diagram shows a clinical thermometer.Which factor affects the sensitivity of the thermometer?
- A.
The diameter of the bore
- B.
The constriction
- C.
The thickness of the glass tube
- D.
The length of the glass tube
Correct Answer
A. The diameter of the boreExplanation
The sensitivity of a clinical thermometer is affected by the diameter of the bore. A smaller diameter bore allows for a greater expansion of the liquid inside the thermometer when there is a change in temperature, resulting in a more sensitive reading. A larger diameter bore would have less expansion of the liquid for the same change in temperature, making it less sensitive. Therefore, the diameter of the bore is a crucial factor in determining the sensitivity of the clinical thermometer.Rate this question:

A certain liquid is used in a liquid-in-glass thermometer. It does not expand uniformly with temperature. What effect will this have on the scale of the thermometer?
- A.
It will be non-linear.
- B.
It will have a small range.
- C.
The markings will be close together.
- D.
The markings will be far apart.
Correct Answer
A. It will be non-linear.Explanation
If the liquid used in a liquid-in-glass thermometer does not expand uniformly with temperature, it means that the volume of the liquid does not increase or decrease at a constant rate as the temperature changes. This will result in a non-linear relationship between the temperature and the volume of the liquid. As a result, the scale of the thermometer will not be evenly spaced and the markings will not be equally spaced apart. Instead, the markings will be closer together in some regions and farther apart in others, leading to a non-linear scale.Rate this question:

What makes a clinical thermometer suitable for measuring small changes in body temperature?
- A.
The amount of mercury in the bulb is small.
- B.
The bore of the capillary tube is narrow.
- C.
The capillary tube is long.
- D.
The glass bulb has a thin wall.
Correct Answer
B. The bore of the capillary tube is narrow.Explanation
A clinical thermometer needs to be able to measure small changes in body temperature accurately. The bore of the capillary tube being narrow allows for more precise measurements because it restricts the movement of the mercury inside the tube. This means that even a small change in body temperature will result in a noticeable change in the position of the mercury in the tube, allowing for accurate readings.Rate this question:

A liquid-in-glass thermometer consists of a bulb containing a liquid which expands into a very thin capillary tube.The liquid in the thermometer is replaced by the same volume of a different liquid that expands more for the same temperature rise. The new thermometer will have
- A.
Greater sensitivity and a greater range.
- B.
Greater sensitivity but a smaller range.
- C.
The same sensitivity and the same range.
- D.
The same sensitivity but a greater range.
Correct Answer
B. Greater sensitivity but a smaller range.Explanation
When the liquid in the thermometer is replaced by a different liquid that expands more for the same temperature rise, the new thermometer will have greater sensitivity because the liquid will expand more and show a larger change in volume for a given change in temperature. However, the range of the thermometer will be smaller because the liquid will reach its maximum expansion more quickly, limiting the range of temperatures that can be accurately measured. Therefore, the correct answer is greater sensitivity but a smaller range.Rate this question:

A liquid-in-glass thermometer contains mercury. Which physical property of the mercury varies with temperature, enabling the thermometer to operate?
- A.
Volume
- B.
Melting point
- C.
Resistance
- D.
Mass
Correct Answer
A. VolumeExplanation
The physical property of mercury that varies with temperature and enables the thermometer to operate is volume. As the temperature increases, the volume of the mercury expands, causing it to rise in the glass tube of the thermometer. Conversely, as the temperature decreases, the volume of the mercury contracts, causing it to lower in the tube. This change in volume is used to measure and indicate the temperature.Rate this question:

The temperature shown by a mercury-in-glass thermometer increases. Which of the following is constant?
- A.
The mass of the mercury
- B.
The density of the mercury
- C.
The internal energy of the mercury
- D.
The volume of the mercury
Correct Answer
A. The mass of the mercuryExplanation
The mass of the mercury remains constant because mass is a measure of the amount of matter in an object, and it does not change with temperature. As the temperature increases, the mercury expands, causing an increase in volume. However, the density of the mercury, which is the mass per unit volume, remains constant because the mass does not change. The internal energy of the mercury increases with temperature as the kinetic energy of the particles increases. Therefore, the only option that remains constant is the mass of the mercury.Rate this question:
