Alcohol
Mercury is toxic and poses serious health and environmental risks if spilled. As a result, many countries have phased out the use of mercury in consumer products, including thermometers. Safer alternatives, such as digital thermometers, are now widely used instead of mercury-based ones.
Mercury was used in old thermometers because mercury expands when it reaches a certain temperature, so it was a really good "gauge". Now, they stopped making thermometers with mercury as the liquid since it was very poisonous. i hope you liked the answer!
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
Common fluids used to measure temperature include mercury, alcohol, and thermochromic liquids. Mercury is toxic and less commonly used now, while alcohol-based fluids are safer alternatives. Thermochromic liquids change color with temperature variations, making them visually helpful for temperature readings.
I don't know to what extent mercury is still being used, but it makes sense to phase it out: mercury is extremely toxic. If a mercury thermometer breaks, you have to be careful not to breathe the vapors.I don't know to what extent mercury is still being used, but it makes sense to phase it out: mercury is extremely toxic.

The metal that was used in thermometers was mercury, however now alcohol is usually used.
Mercury is commonly used in thermometers due to its unique properties, such as its ability to expand uniformly with temperature changes. However, due to its toxicity, digital thermometers with safer alternatives like alcohol or gallium are now more widely used.
they used to use mercury but now they use a type of alcohal
Mercury was commonly used in thermometers and barometers. However, because it is poisonous, people are trying to use it in less things now.

Mercury.
Mercury has many uses but the first one that comes to mind, is the use for this metal in thermometers. Mercury is, to my knowledge, the only metal that can be a liquid at room temperature. This metal is also used in making other instruments such as barometers.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
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.
