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

mercury has better thermoconductiity and they have a greater range of readings
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.
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.
it can be easily seen it gets hot quickly it expands fast.. this is the advantage of mercury in thermometers..
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.

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.
