No. But glassware is not a crystalline rigid material, and has some memory of recent thermal movement.
Thermometers that have been calibrated at manufacture, will have a couple of tiny scratch marks along the scale, and the graduations in between are interpolated. If you wish to calibrate a thermometer, then do so at the triple point (close to 0 deg C), and at boiling point - 100 degree C. Since much of the stem of the thermometer has been at 100 degree C, straightaway after removing from the steam, the glass tube will shrink, and the reading will change due to this, as well as the mercury column cooling.
For a thermometer to be a precision measuring device, the bore has to be accurately true, and this is not always the case. Ordinary mercury thermometers are seldom to be relied upon for better than 1 degree C resolution.
Mercury in a thermometer does not go bad if properly stored and handled. However, if the thermometer is damaged or the glass is broken, the mercury can escape and pose a health hazard. It is important to dispose of a broken thermometer properly to prevent exposure to mercury.

Why can a mercury thermometer be used only at high temperatures?
A mercury thermometer can go down to -30 deg C
Which thermometr will you take when you go to south expedition mercury or alchol?
An Alcohol thermometer would be the best as it is more sensitive than the mercury thermometer.
What is the sSensor in Mercury-in-glass thermometer?
The sensor in a mercury-in-glass thermometer is the glass bulb at the base of the thermometer containing the mercury. The temperature is measured by the expansion or contraction of the mercury based on the surrounding temperature, allowing the thermometer to provide a temperature reading.
Why do you like Mercury?
i like mercury because it is inside a thermometer
How does the kink in a mercury or alcohol work in a clinical thermometer?
The kink in a mercury or alcohol clinical thermometer helps to prevent the mercury or alcohol from flowing back into the bulb once the thermometer is removed from a patient's body. This ensures that the maximum temperature reached during measurement is retained for reading.
Why can a mercury thermometer be used only at high temperatures?
A mercury thermometer can go down to -30 deg C
Why does the mercury in the thermometer go up when the temperature is high?
In a mercury thermometer, the mercury expands when it is heated, causing it to rise in the thermometer's narrow tube. This increase in volume is a physical property of mercury known as thermal expansion. The height of the mercury column in the thermometer is then used to measure the temperature.
Which thermometr will you take when you go to south expedition mercury or alchol?
An Alcohol thermometer would be the best as it is more sensitive than the mercury thermometer.
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
Why doesn't the mercury on a medical thermometer go down when it's removed from the body?
The mercury on a medical thermometer does not go down when removed from the body because the mercury expands to a certain level when it comes in contact with body heat, and even after it's removed, it does not contract back immediately. The thermometer needs to be shaken or reset for the mercury to go back down to its starting point.
Why do you use mercury thermometer?
As tempertature rises, the Mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli
Why is putting a thermometer bulb in a flame a bad idea?
Putting a thermometer bulb in a flame is a bad idea because the intense heat of the flame can cause the glass to shatter, releasing toxic mercury vapor into the air. This can be harmful to your health and the environment. It can also damage the thermometer and make it inaccurate.
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
What is Mercury thermometer use to measure?
A mercury thermometer is used to measure temperature.
Mention any two points of difference between a clinical thermometer and an ordinary mercury thermometer?
A clinical thermometer will offer more precise calibrated readings than a mercury thermometer. The range of measurable temperature differs between a clinical and a mercury thermometer with the mercury thermometer having the wider range.
Why mercury go down and up suddenly in a thermometer?
Depending on Atmospheric Pressure
What causes mercury in a thermometer to rise?
The mercury in a thermometer rises because of thermal expansion. When the temperature surrounding the thermometer increases, the molecules of the mercury expand, causing it to move up the narrow tube of the thermometer.
