Three different types of thermometers are :- 1. Liquid thermometer 2. Digital thermometer 3. Laser thermometer
Mecury- only liquid metal at room temperature.
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.
A thermometer can use any of several methods to register temperature. These include mercury; liquid-in-glass; electronic with digital display; infrared or tympanic; and disposable dot matrix
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
I think that thermometers (liquid) were once filled with mercury. Xo, Smartiiz.
a temperature-measurement device whose operation is based on the thermal expansion of a liquid. Liquid-filled thermometers provide a direct reading of the temperature.
Most digital thermometers use liquid crystal displays that cannot be repaired.

Mercury is used in thermometers.
Mercury in thermometers is in a liquid state, since mercury is liquid at room temperature.
Three different types of thermometers are :- 1. Liquid thermometer 2. Digital thermometer 3. Laser thermometer
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.
the element used in termometers is Mercury.
For non-electronic thermometers , you will either see a red liquid or a silver liquid. The 'Red liquid' is a coloured alcohol. The 'Silver liquid' is mercury.
Liquid in glass thermometers are fragile.For precise work, they need to be recalibrated frequently.
For a basic design of thermometers would base on the principle of thermal expansion, either using air in syringe expand and contract with temperature to indicate the scale or using liquid filled into capillary and mark the scale according to a standard thermometer.
