What is best known to be used in thermometers?

Answer 1

It depends on the thermometer. An old-style liquid thermometer might contain: * Mercury (silvery) * alcohol (usually dyed red or blue for visibility) * an alloy of sodium and potassium (silvery) * an alloy of gallium, indium, and tin (silvery) * any of a number of other things depending on the temperature range to be measured Electronic thermometers contain a thermocouple plus electronics to turn the potential generated by the thermocouple into a temperature reading.

Answer 2

Common household thermometers used to have mercury in them, but mercury is dangerous, so most thermometers nowadays only have very tiny amounts of it. Instead of mercury, they often use a substance called galinstan. See the Related Link below.

Answer 3

Mercury use to be the most commonly used fluid in thermometers. Now, because of concerns about the toxicity of mercury should it be released from a broken thermometer, they use red alcohol in most liquid thermometers.

Answer 4

usually mercury (quick silver) although now days it might be something else which is not toxic.

Answer 5

Often Mercury is in Thermometers because it is a liquid at room temperature and expands with heat. But due to the dangers associated with Mercury it is being used less.
