The two most common liquids used in glass thermometers are Mercury and alcohol, both of which were created by M. Nature. Alcohol thermometers are, or were, used in extremely cold areas like the Yukon, where the temperature could be expected to drop lower than -40 in the winter (-40 is where mercury freezes, and it is also the only temperature that is exactly the same on both Fahrenheit and Celsius thermometers).

What is liquid-in-glass thermometer?
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
Which device has a liquid in glass components?
thermometer
What are the materials in a thermometer?
For a classic thermometer: glass and mercury, colored ethanol or another liquid.
Why are the thermometers called liquid in glass thermometers?
A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
How does a liquid in a glass thermometer?
the heat makes it expand you see
What are the characteristics of the liquid used in a liquid in glass thermometer?
The liquid in a liquid-in-glass thermometer is typically a colored alcohol, such as ethanol or dyed ethanol, to aid in visibility. It has a low freezing point to ensure it remains in liquid form within the thermometer's temperature range, and it expands and contracts uniformly with temperature changes for accurate readings.
What is the different between clinical thermometer and liquid in glass thermometer?
a lab thermometer did not have a constriction as compared to clinical thermometer. it have a wide range of measurement and usually contains alcohol
How is a glass thermometer read accurately?
To read a glass thermometer accurately, hold it at eye level and look at the level of the liquid inside the tube. The temperature is where the liquid stops rising. Make sure the thermometer is clean and not tilted for an accurate reading.
What is a laboratory thermometer?
A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.
What is a glass bulb of a thermometer?
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
What are the characteristics of the liquid used in a liquid in a glass thermometer?
The liquid in a glass thermometer is typically a non-toxic and non-reactive liquid such as mercury or colored alcohol. These liquids have a high coefficient of thermal expansion, allowing them to accurately measure temperature changes by expanding or contracting within the narrow capillary tube of the thermometer.
What are the materials used for a Galileo thermometer?
A Galileo thermometer is a thermometer made of a sealed glass cylinder containing a clear liquid and a series of objects whose densities are such that they rise or fall as the temperature changes.
