Who made the first mercury thermometer?
Galileo invented an air thermometer in about 1600, but changes in atmospheric pressure made accurate measurement difficult. Liquids were quickly used instead and Gabriel Fahrenheit was the first to use alcohol (1709) and mercury (1714), in a thermometer.
Does a red thermometer smell?
If it is a modern version, yes. Most "air temperature" thermometers use colored alcohol mixes instead of mercury (the vapor of which can be very toxic).
What type of liquid do you use in a thermometer?
Mercury and alcohol [liquid elements]
What happen to the liquid in a thermometer when it gets warm?
The liquid expand from heat. We use these expansion to indicate temperature. Common thermometer liquid is Mercury and alcohol.
What is the name of the liquid in a thermometer?
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
What is Mercury thermometer use to measure?
A mercury thermometer is used to measure temperature.
What is in a thermometer besides Mercury?
There is nothing else in a mercury thermometer. However, some similar (glass tube-type) thermometers contain alcohol instead of mercury. Ray

What is liquid-in-glass thermometer?

Why use mercury for a thermometer?
Because it does not freeze or evaporate
Define vapor pressure thermometer?
A thermometer which utilizes a gas(vapor) to react to temperature changes for an accurate reading. (Instead of a hazardous material such as a mercury filled thermometer.)
Why cant you use a mercury thermometer to measure the melting point of gold?
The thermometer would melt
Would you rather use alcohol or Mercury in a thermometer?
Alcohol. Mercury is very toxic.
Why do you use mercury thermometer?
As tempertature rises, the Mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli
