Because the thermal expansion is higher from alcohol (ethanol) and then it's more precise.
Alcohol also reacts to heat by expanding and contracting and is much safer to use than mercury which is a neurotoxin that can make you very sick if the thermometer were to break and you got in contact with it.
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 thermometers were commonly used in schools because of their accuracy and reliability in measuring temperature. They were also economical and easy to read. However, due to the toxicity of mercury, many schools have phased out mercury thermometers in favor of safer alternatives.
Schools are destroyed when teachers teach to the standardized test instead of teaching the content of the class.
Temperature can be measured using a thermometer, which can be found in various places such as homes, schools, hospitals, laboratories, and weather stations. Digital thermometers are commonly used for quick and accurate temperature readings, while mercury thermometers are being phased out due to environmental concerns.
