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.

Some times red coloured liquid is used but mostly gray coloured liquid is used.
Mercury thermometers have advantages over alcohol thermometers. The liquid is visible making the results easy to read. It expands at a regular interval. It measures temperature quickly and accurately.
the element used in termometers is Mercury.
Mercury is used in thermometers.
it is mercury. its actually a liquid at room temperature.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).

Most thermometers used to contain Mercury until it was found to be toxic.

Mercury (Atomic number 80) is still used in some thermometers.

The first devices to measure temperatures did not use liquid mercury (Hg) as commonly thought. Hg thermometers came centuries later in fact. Among the first thermometers were bulbs in water used to measure temperature.

Mercury is a liquid metal used in thermometers. However, it becomes a solid at -37.9 F and it can cause mercury poisoning if ingested or inhaled. Therefore, most theremometers use ethyl-alcohol or a plastic strip covered with liquid crystals (called a liquid crystal thermometer).
