The simple answer is because of it's relatively low freezing point, -38 Fahrenheit.
Digital thermometers have replaced mercury thermometers because mercury is toxic. [Personal commentary: digital thermometers are not accurate and mercury thermometers are so how many people are being harmed by not knowing their temperature versus how many would be harmed by the mercury if accurate thermometers were still used?]
Mercury thermometers are used domestically because they are reliable, have a wide temperature range, and are easy to read. Alcoholic thermometers are used in labs because they are non-toxic and can measure a wide range of temperatures accurately. Additionally, they have a lower risk of shattering compared to mercury thermometers.
Mercury is toxic and poses serious health and environmental risks if spilled. As a result, many countries have phased out the use of mercury in consumer products, including thermometers. Safer alternatives, such as digital thermometers, are now widely used instead of mercury-based ones.
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.
Mercury is used in thermometers.
Mercury was used in old thermometers because mercury expands when it reaches a certain temperature, so it was a really good "gauge". Now, they stopped making thermometers with mercury as the liquid since it was very poisonous. i hope you liked the answer!
mercury was used for thermometers and baramoters
Most thermometers used to contain Mercury until it was found to be toxic.
in thermometers.
Mercury is the element commonly used in liquid-in-glass thermometers.
No, mercury is not present in all types of thermometers. While mercury thermometers are common, other types such as digital thermometers and infrared thermometers do not contain mercury. Mercury thermometers are being phased out due to environmental concerns.
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.
