There cannot be an answer to this question because it is based on a false premise that only mercury should be used. That is simply not true.
only in a thermometer
A mercury thermometer is used to measure temperature.
Mercury
to check the temperature
what do they use for the liquid in glass ball thermometer
Because it does not freeze or evaporate
the mercury should be at normal body temperature level before using it the thermometer should be cleaned after use with normal water the bulb of the thermometer should not be touched
The thermometer would melt
Alcohol. Mercury is very toxic.
As tempertature rises, the mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli

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.
