alcohol and mercury thermometers- why are they different? and when and where are they used?

  • science -

    Both of these thermometers were designed to rise and fall as they expand or contract with changes in temperature. One major difference is that alcohol thermometers will only rise when on site with the temperature to be read, where as a mercury thermometer needs to be shaken if you want to take another reading. The mercury will generally stay risen, as opposed to the alcohol which will imediatly drop when the temperature source is removed. Many doctor clinics will use mercury thermometer, where a Laboratory will use alcohol.
