the thermometers which are used to find your temperature
They are used in thermometers to let us see the heat of the object you are measuring, if you use solid, it wouldn't be able to move up, if you use gas, it will fill the whole container, so it's better to use liquid
Most thermometers used to contain Mercury until it was found to be toxic.

Mercury (Atomic number 80) is still used in some thermometers.
Mercury and alcohol (ethanol).
they used to use mercury but now they use a type of alcohal
Different types of thermometers work differently, by measuring some property that changes with temperature. The model commonly used in households uses the fact that liquids expand when heated.
if you mean what are the two most commonly found liquids in a liquid-and-glass thermometer then the answer is mercury and alcohol :) hope this helps
Mercury is used in thermometers.
Infrared thermometers are primarily used in the kitchen, for measuring the temperatures of hot liquids and solids. A good writeup on infrared thermometers and its method of working is on http://www.allqa.com/IR.html.There are some industrial applications as well.
Mercury thermometers are rarely used, except in lab thermometers. For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
the thermometers which are used to find your temperature
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).
The alcohol is volatile, and gas pressure will increase in the space above the liquid, making readings inaccurate (and threatening the integrity of the glass tube). Above about 78 °C (172 °F), ethanol-based thermometer liquids will boil, so these thermometers should not be used.
Mercury is not used in thermometers, because mercury is poisonous.
In normal and some medical thermometers Mercury is used. That is why you may want to consider using electric thermometers which are more commonly used. They use no mercury.
