Most traditional thermometers contain Mercury as the liquid inside. However, modern thermometers use alcohol or a similar non-toxic liquid.
Clinical thermometers used to use Mercury, but since mercury is poisonous, they now use Ethyl Alcohol in clinical thermometers.

What are 3 main different types of thermometers?
The three main types of thermometers are liquid-in-glass thermometers, digital thermometers, and infrared thermometers. Liquid-in-glass thermometers use a liquid like mercury or alcohol to measure temperature, digital thermometers provide a numeric temperature reading, and infrared thermometers measure temperature from a distance using infrared technology.
What are the disadvantages of liquid in glass thermometer?
Liquid in glass thermometers can break easily, leading to hazardous leaks of the toxic liquid inside. They are also relatively slow to respond to temperature changes compared to digital thermometers. Additionally, they can be difficult to read accurately due to parallax errors.
What material is used to make thermometers?
Thermometers are typically made using glass, as it is transparent and durable. Mercury or alcohol are commonly used as the liquid inside the glass tube to measure temperature. Some modern thermometers may use digital sensors and components instead of traditional materials.
How does thermometers measure temperature?
Thermometers measure temperature by using liquids (like mercury or alcohol) that expand and contract based on temperature changes. As the liquid expands, it rises in a narrow tube to indicate the temperature. The scale on the thermometer is calibrated to show the temperature based on how much the liquid expands or contracts.
Which device is used to measure air temperature?
A thermometer is used to measure air temperature. Several types of thermometers can be used, such as liquid-in-glass thermometers, digital thermometers, and infrared thermometers.
What type of liquid do you use in a thermometer?
Typically, thermometers use either mercury or alcohol as the liquid inside the glass tube to measure temperature. Mercury thermometers are being phased out due to the toxicity of mercury, with alcohol thermometers being a safer alternative.
What are 3 main different types of thermometers?
The three main types of thermometers are liquid-in-glass thermometers, digital thermometers, and infrared thermometers. Liquid-in-glass thermometers use a liquid like mercury or alcohol to measure temperature, digital thermometers provide a numeric temperature reading, and infrared thermometers measure temperature from a distance using infrared technology.
What liquid mental is used for thermometers?
Mercury is used in thermometers.
What are the disadvantages of liquid in glass thermometer?
Liquid in glass thermometers can break easily, leading to hazardous leaks of the toxic liquid inside. They are also relatively slow to respond to temperature changes compared to digital thermometers. Additionally, they can be difficult to read accurately due to parallax errors.
What is the state of mercury in a thermometers?
Mercury in thermometers is in a liquid state, since mercury is liquid at room temperature.
What element is liquid metal used in the thermometers?
Mercury is the element commonly used in liquid-in-glass thermometers.
What are the two substances used in a liquid column thermometer?
The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.
What type of metal is liquid at room temperature?
Mercury in thermometers: they expand and shrink but are still liquids inside the thermometer. It is still considered a metal and it is liquid at room temp.
How do thermometers with in liquid in glass measure temperature?
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.
Why liquid in glass thermometers are not suitable for industrial work?
Liquid in glass thermometers are fragile.For precise work, they need to be recalibrated frequently.
What are the two substance used in liquid column thermometers?
iodine and Mercury
What is the liquid in a thermomether called?
Some thermometers use mercury, in these the liquid is silvery. Some thermometers use a red dyed alcohol solutioin.
