Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
To increase the sensitivity of the thermometer, that is, for the thermometer to respond quickly to small changes in temperature.
Why does a mercury-in glass thermometer first drop slightly when placed in boiling water?
When placed in boiling water, the materials comprising the thermometer respond in the order in which the heat penetrates them. As the heat first permeates the glass cylinder, the cylinder expands, enlarging the bore. For the moment until the mercury is also heated, the constant volume of mercury fills the expanded bore to a slightly lower depth. When the heat reaches the mercury and it also expands, its volume to increase, and the liquid depth rises in the bore.
What are the disadvantages of shielding a thermometer?
Shielding a thermometer may have some disadvantages, including: Inaccurate readings: If the thermometer is shielded improperly, it may affect the temperature readings by blocking heat or cooling that should be reaching the thermometer. Slow response time: If the thermometer is shielded too much, it may not be able to respond to temperature changes quickly, which can lead to inaccurate readings or delayed readings. Uneven temperature distribution: If the thermometer is shielded, it may not be able to measure the temperature of the surrounding environment accurately, which can lead to uneven temperature distribution. Difficulty in calibration: Shielding the thermometer can make it difficult to calibrate and maintain, which can affect its accuracy over time. Increased cost: Adding a shield to a thermometer may increase the cost of the device and add complexity to its design, which can make it more expensive to produce and maintain. In summary, while shielding a thermometer may be useful in certain circumstances, it can also have some drawbacks that may affect the accuracy and reliability of temperature readings. It is important to consider the specific application and environment before deciding whether to shield a thermometer or not.
What is the sensitivity of an instrument?
The sensitivity of an instrument is the smallest amount it can measure, of whatever it's built to measure.Anything smaller than the sensitivity of the instrument, and the instrument doesn't even notice it.For example, a laboratory scale can measure the weight of a hair, but a truck scale can't. We say that thelaboratory scale's sensitivity is much smaller (or lower) than the truck scale's sensitivity.

How does the volume of mercury affect the responsiveness to temperature of a liquid-in-glass thermometer?
The more mercury there is, the slower the response time will be. If one has to warm more mercury to make it respond, then it will take longer to respond given the same amount of heat input.
What is the importance of thermometric liquids?
Thermometric liquid is the liquid found in the thermometer that help in the up and down movement of the temperature.
A student claims that the thermometers are useless because a thermometer always registers its own temperature. how would you respond?
It is true that thermometers always registers its own temperature.When thermometers are in contact with a respective body heat is exchanged between the thermometer and the body.After some time they are in equilibrium state.As both of their temperature are now the same, temperature of thermometer is registered equal to that of the body as a result.

When thermometer is laid ouside the sun does it measure suns temperature or air temperature?
If a thermometer is laid out in direct sunlight, it will not measure the temperature of the air surrounding it. It will measure the temperature of the heat directly reaching it.
