alcohol thermometres are used to measure very low temperatures(upto -112 degree celsius) and mercury to measure very high temperatures (upto 357 degree celsius).
Before the use of mercury, alcohol (usually ethanol or dyed spirits) was commonly used in thermometers. Alcohol thermometers were popular because alcohol has a lower freezing point than mercury, making them suitable for a wider range of temperatures.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
Alcohol-based thermometers are used in labs because alcohol has a lower freezing point than mercury, making them suitable for lower temperature measurements. Additionally, alcohol is less toxic than mercury, reducing potential health and safety risks in laboratory settings.
Mercury thermometers are still used in some industrial applications and laboratories due to their accuracy and ability to measure high temperatures. However, their use is declining due to the potential health and environmental risks associated with mercury exposure. In many situations, digital thermometers or other types of non-mercury thermometers are used instead.
Thermometers can be made from various materials, but common ones include glass, mercury, alcohol, and digital sensors such as thermocouples and resistive temperature detectors. Glass thermometers often contain mercury or alcohol as the temperature-measuring substance. Digital thermometers use semiconductor materials for temperature sensing.
Mercury and alcohol
Water was initially used and later on alcohol was used.
Mercury and alcohol (typically ethanol or dyed alcohol) are two liquids that have been commonly used in thermometers. Mercury is often used in industrial thermometers due to its high thermal conductivity, while alcohol is used in household thermometers for safety reasons.
iodine and Mercury
The two most commonly found liquids in liquid-in-glass thermometers are mercury and alcohol. Mercury thermometers are used for high-temperature applications, while alcohol thermometers are used for lower temperatures due to their lower toxicity.

It must not. Mercury is very toxic. It's safer to use colored alcohol in thermometers.
Thermometers typically use a metal such as mercury or alcohol to measure temperature. Mercury thermometers are commonly used in applications such as medical settings, while alcohol thermometers are used in environmental monitoring due to their lower environmental impact.
Alcohol or mercury are commonly used as the fluids in thermometers. Mercury was commonly used in the past but is being phased out due to its toxicity. Alcohol is a safer alternative that is used in most modern thermometers.
Yes, alcohol is commonly used nowadays.
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
Mercury is highly poisonous and should not be used in milk production. The only place where mercury might be used in milk production is in mercury thermometers and where possible, these should be replaced with alcohol thermometers.
