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.

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.
Which thermometer is a greater health hazard if it breaks Is it the mercury in glass or alcohol in glass thermometer?
Mercury is poisonous.
Why do you like Mercury?
i like mercury because it is inside a thermometer
Is the external bulb of a thermometer also made of mercury?
The red liquid in a thermometer is Mercury, which is usually encased in a glass tube

Why is putting a thermometer bulb in a flame a bad idea?
It is a very good idea for the thermometer manufacturer, but it is a very bad idea for you because the thermometer bulb may blow out and release the dangerous mercury stored inside.
Why do you use mercury in 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

The function of a Mercury thermometer?
to tell old people that have a mercury thermometer what the temperature is
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
Why doesn't the mercury on a medical thermometer go down when it's removed from the body?
There is a kink put in the tube which carries the mercury up the thermometer, that is why it needs to be shaken to send it back to the bulb
What is the liquid in thermometer's called?
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
Who invented the modern mercury thermometer and when?
The mercury thermometer was invented Daniel Gabriel Fahrenheit in 1714.
