What do they use instead of mercury in thermometers?

Answer 1

There are a variety of cost-effective, Mercury-free alternatives available at local pharmacies. These alternatives include digital, glass gallium-tin, and glass alcohol thermometers. Because of the health risks associated with mercury exposure from broken thermometer, it is very difficult any more to find glass mercury thermometers.

Answer 2

A liquid used in termometers should probably have the caracterstics such as having a high melting point, opaque, uniform expanding rate etc. One such liquid is alcohol. It has a melting point of 110 degree celsius. Such thermometers are usually found in laboratories.

Answer 3

Some thermometers (the red or blue "weather" type thermometers) have used colored alcohol for years. There's been a bit of a push to eliminate mercury from the more precise lab thermometers, though, and it's now possible to buy thermometers that use a gallium alloy ("galinstan") that melts at around 254 K. These are a bit more difficult to produce than mercury thermometers, though, since gallium wets glass... an undesirable property in a thermometer.

Answer 4

Hardly any options in contrast to mercury have now been created. One of which incorporates galinstan that is a fluid compound of gallium , indium and tin. Liquor Thermometers. Alcohol thermometers are supplanting mercury thermometers in numerous applications. They utilize liquor as the filled in fluid in glass tubes.

Answer 5

Typically, thermometers with a red liquid are filled with an alcohol that contains a dye. These are called "spirit-filled".

Answer 6

Because of the toxicity of mercury, most thermometers these days are manufactured using alcohol that's been colored (usually red) to make it easier to see.

Answer 8

They used to.

But it's quite poisonous and bad for the Environment, so it's been replaced by less dangerous substances.

Answer 9

Mercury is a good conductor of heat and it expands to certain levels when heated to certain temperatures. Water would freeze when the temperature went below 32 degrees F. or 0 degrees C

Answer 10

Non metals that are used include Alchol, air, liquid crystals and quartz.
