iodine and Mercury
The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.
Mercury is the element commonly used in liquid-in-glass thermometers.
The densest liquid substance is mercury. It has a high density compared to other liquids, which makes it commonly used in barometers and thermometers.
Some times red coloured liquid is used but mostly gray coloured liquid is used.
The red substance in a thermometer is typically mercury. Mercury is used in thermometers because it expands and contracts uniformly with changes in temperature, making it an effective liquid for measuring temperature accurately.

Mercury is the element commonly used in liquid-in-glass thermometers.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).

Mercury is the metal element traditionally used in thermometers due to its ability to expand and contract uniformly with changes in temperature. However, due to its toxicity, mercury thermometers are being phased out in favor of digital alternatives.

Mercury (Atomic number 80) is still used in some thermometers.
Most thermometers used to contain mercury until it was found to be toxic.

A thermometer is used to measure air temperature. Several types of thermometers can be used, such as liquid-in-glass thermometers, digital thermometers, and infrared thermometers.
