Yes, it's quite harmful for humans.
Mercury in a thermometer is poisonous if it is inhaled or ingested. When a thermometer breaks, mercury vapor can be released into the air, which can be harmful if breathed in. Additionally, if mercury is ingested, it can be absorbed into the bloodstream and cause poisoning.
you die because it is poisonous. of course
It could be used to do this - it is capable of doing it. However, Mercury is poisonous and a mercury thermometer is made out of fragile glass. Thus the danger that the thermometer would break releasing mercury into the milk (which would be for a person to drink) means that a mercury thermomiter is not the temperature sensor to use in this instance.
Mercury.
because it is more cheaper then the mercury one and less poisonous
You can't and shouldn't repair this. Mercury being poisonous, it is best recommended to discard the whole thermometer, without letting the mercury escape, very carefully. Maybe where you live they have a special place where such objects are destroyed safely.
It was mercury but when they found out they were poisonous when broken they started to use it less often, but it is still sold., but not very much
Mercury in glass thermometers pose a greater health hazard if broken, as mercury is a toxic substance that can be harmful if inhaled or ingested. Alcohol in glass thermometers are considered less hazardous as alcohol is not as toxic as mercury. It is still important to clean up any broken thermometer carefully to avoid injury.
The silver-colored liquid inside a thermometer is typically mercury, which is a heavy metal that expands and contracts with changes in temperature, allowing the thermometer to measure and display the temperature accurately.
Mercury in a Mercury thermometer is typically silver in color.
Mercury is poisonous... If the thermometer is broken - it could cause harm. It's safer to use alcohol thermometers - or electronic ones.
Mercury expands when heated, and the rate at which it expands can be calibrated in a thermometer to fit to a scale, which you see as the markings in the thermometer. We use mercury because of its ability to expand with just a little amount of heat. Because mercury is poisonous, we now use alcohol thermometers. Alcohol is just as good as mercury because it expands when heat is applied to it as well.
