thermometers today are used to generally see what the temperature in a room is they mainly use Mercury to find this out :)
to check somones temperature
Mercury thermometers are rarely used, except in lab thermometers. For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
Mercury is used in thermometers barometers and flourescent lightbulbs.
Mercury used to be a popular element for thermometers, but I think it's illegal to make a mercury thermometer because if you break one you have a hazardous situation on your hands. Today thermometers that contain liquid, almost always contain alcohol.
Mercury is used in thermometers.
Alcohol is most common in modern thermometers. Early thermometers used mercury, but these pose a possible health threat. Today, both are being replaced by electronic instruments.
Dozens of different types of thermometers are in use today, from mercury to alcohol to bi-metal coil to solid-state.
the thermometers which are used to find your temperature
Mercury is not used in thermometers, because mercury is poisonous.
In normal and some medical thermometers Mercury is used. That is why you may want to consider using electric thermometers which are more commonly used. They use no mercury.
These days, mercury is considered too risky to use in thermometers (due to the risk of them breaking and contaminating people). Alternate techniques are used today in clinical thermometer, including electronic thermometers and ones based on liquid crystals that aren't as harmful should they leak out and even contactless infrared thermometers..Mercury was used in clinical thermometers due to:Its high thermal expansion (25 °C) 60.4  µm·m−1·K−1Linearity in thermal expansionSensitivity to rise in temperature
Most thermometers used to contain Mercury until it was found to be toxic.
