Question

which thermometer does not use mercury​

Answer 1

Answer:

Digital thermometers and Spirit thermometers does not use mercury

Explanation:

Digital thermometer - These thermometers do not use mercury and they have dedicated electronic circuits to measure temperature.

• They are much safe as they do not use mercury, since they pose significant risks when they break or if disposed of improperly.

• Mercury is a highly toxic metal, and  too much exposure to it can cause severe health related problems including neurological disorders.

Spirit thermometer – Here, the bulb of the thermometer is filled with alcohol, toluene or kerosene as the temperature sensor.

• Less toxic and less durable because alcohol evaporates quickly, whereas the mercury thermometer is highly durable, as the mercury does not evaporate easily.
