Mercury does not wet the surface of glass, expands with little heat & it is shining white which helps in reading.

What are the disadvantages of using thermometers that do not contain mercury?

Some disadvantages of using thermometers that do not contain mercury include potential environmental impact due to the use of alternative materials like alcohol or digital sensors, lower accuracy compared to mercury thermometers, and the potential for the thermometer to break more easily. Additionally, non-mercury thermometers may be less durable and have a shorter lifespan.


Why mercury thermometers are not used in schools?

Mercury is a toxic substance that can be harmful if the thermometer breaks and the mercury is released. In schools, there is a risk of accidental breakage and exposure to students and staff. As a result, schools have shifted to using safer alternatives like digital thermometers.


Why is mercury no longer used in thermometer?

Mercury, if it enters your body, causes severe brain problems, and is usually deadly, so it is a poisonous material. it is no longer used in thermometers because thermometers were breaking and too many people were dying.


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.


Why did they stop making Mercury thermometers?

Mercury is toxic and poses health risks if the thermometer breaks and the mercury is ingested or inhaled. Due to health and environmental concerns, many countries have banned the production of mercury thermometers and have switched to safer alternatives like digital thermometers.

Is Mercury used in thermometers?

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.


Why do OSHA and EPA and the AMA all discourage the use of mercury filled clinical thermometers?

When mercury filled thermometers break, the mercury is released. Mercury is toxic to people, pets and the environment. There is a long history of mercury from broken thermometers and other medical devices being improperly dealt with, or even ignored. Since there are adequate replacements for mercury thermometers, OSHA, EPA, AMA and others discourage the use of mercury thermometers and encourage their replacement with thermometers using other technologies.

What are some advantages of using mercury thermometers?

mercury has better thermoconductiity and they have a greater range of readings


How much do mercury thermometers cost?

Mercury thermometers can range in price from $5 to $30, depending on the brand, accuracy, and size. However, due to safety concerns regarding mercury exposure, many places are moving towards using digital thermometers instead.


How are thermometers and bermometers?

Thermometers measure temperature, typically using mercury or digital sensors. Berometers are not a standard scientific instrument and may refer to barometers, which measure atmospheric pressure. Both devices provide valuable information for understanding environmental conditions.


What are the advantage of using Mercury in thermometer?

it can be easily seen it gets hot quickly it expands fast.. this is the advantage of mercury in thermometers..


Why do you flick thermometers before using them?

This is only in the case of of clinical thermometers, which usually have mercury inside them. These thermometers have a constriction just after the bulbthat allows the mercury to flow due to the pressure of expansion and contraction but is thin enough not to allow the mercury back into the bulb, to allow people to read the thermometer without having to hurry. people flick the thermometers to force the mercury back into the bulb so that temperature can be taken again.

How is temperature measured accurately in scientific experiments?

Temperature is accurately measured in scientific experiments using instruments called thermometers. These devices can be filled with liquids like mercury or alcohol that expand and contract with changes in temperature, allowing for precise measurements. Additionally, digital thermometers use electronic sensors to detect temperature changes and provide accurate readings.
