Early thermometers, dating back over two hundred years BC (BCE), were made using air and water. Later, in the time of Galileo (16-1700s AD or CE), these devices were refined;
Galileo used glass spheres containing alcohol to measure temperature, and today working 'Galileo' thermometers using alcohol-filled spheres suspended in water are available from retail outlets, mainly for ornamental use and as curiosities. They are attractive, though not to be considered especially accurate, and are more properly described as thermoscopes.
The original commercially-available thermometers contained mercury. The Mercury thermometer was first made by Prussian-born physicist and glass-blower, Daniel Fahrenheit in 1724. The specifically clinical thermometer was invented in 1866 by British physician, Sir Thomas Albutt.
Electronic thermometers are commonly used now for clinical, industrial and domestic purposes; these produce a digital display and are safer and more accurate than the mercury-in-glass thermometers.
The sale of mercury thermometers is banned in many countries and US states; this is causing quite a few problems because they are still required under many industrial and government standards worldwide.
Resistance temperature detectors (RTDs) contain platinum, either in the form of wire or film. These thermometers also have a digital display.
RTDs are highly accurate and are frequently used in testing the results of other thermometers to industrial standards.

What type of Thermometer is most likely to contain alcohol?
A mercury-in-glass thermometer is most likely to contain alcohol. However, due to safety concerns, many modern thermometers use alcohol-based solutions or other materials instead of mercury.
What liquid metal was commonly used in thermometer?
We still use colored alcohol for our liquid in everyday thermometers.
Why couldn't you use the same thermometer used to determine the initial temperature of the metal to determine the final temperature of the metal and the water?
You cannot use the same thermometer for both measurements because the thermometer may not provide accurate readings after being in contact with the hot metal, potentially affecting its calibration or causing damage. Additionally, if the thermometer is not allowed to equilibrate to the temperature of the metal before measuring, it may give an inaccurate final temperature reading. Using different thermometers ensures that each measurement is reliable and unaffected by prior exposure to extreme temperatures.
What is a vane thermometer?
A vane thermometer is a type of thermometer that uses a metal pointer or vane to indicate temperature. The vane moves along a scale to show the temperature reading. It is commonly used in meteorology to indicate the temperature of the air.
What is the sSensor in Mercury-in-glass thermometer?
The sensor in a mercury-in-glass thermometer is the glass bulb at the base of the thermometer containing the mercury. The temperature is measured by the expansion or contraction of the mercury based on the surrounding temperature, allowing the thermometer to provide a temperature reading.
What type of Thermometer is most likely to contain alcohol?
A mercury-in-glass thermometer is most likely to contain alcohol. However, due to safety concerns, many modern thermometers use alcohol-based solutions or other materials instead of mercury.
What is a thin glass tube with bulb on one end that contains a liquid?
Thermometer. They contain Mercury which is a metal.
What does a wet bulb thermometer contain?
What is the liquid metal in thermometer?
Mercury
What devices contain mercury?
Thermometer or barometer
What liquid metal is use in the thermometer?
Mercury
Why does the thermometer go down when the temp gets cold?
A thermometer measures temperature based on the expansion or contraction of the liquid or metal inside it. When it gets cold, the molecules inside the thermometer contract, causing the liquid or metal to shrink, which in turn results in the reading on the thermometer going down.
Why is the glass stem of a thermometer designed to act like a magnifying glass?
The glass stem of a thermometer is not designed to act like a magnifying glass. Its purpose is to contain the temperature-sensitive liquid or metal that expands or contracts with temperature changes to provide a reading on the thermometer scale. Magnifying glasses have a different purpose of magnifying objects placed beneath them.
What do you use to support a thermometer to a beaker?
a metal stand.
Why 6s maximum and minimum thermometer contain alcohol?
simply
What process can be used to determine which metal gets the hottest?
A thermometer..
What liquid metal is in thermometer?
Most thermometers contain either mercury or alcohol as the liquid metal. Mercury thermometers are being phased out due to the toxicity of mercury. Alcohol-based thermometers are safer and more environmentally friendly.
