The heat on the outside of the thermometer transfers to the glass which transfers to the alcohol making the alcohol expand making it rise
either mercury or alcohol
They both have advantages and disadvantages: A mercury-in-glass thermometer can measure high temperature (up to 357 0C, the boiling point of mercury; and its freezing point is -39 0C). An alcohol-in-glass thermometer can measure low temperature (down to -115 0C, the freezing point of alcohol; and its boiling point is 78 0C.) A mercury-in-glass thermometer can quickly response to temperature, while an alcohol-in-glass thermometer can only slowly response to temperature. However, mercury is poisonous and alcohol is NOT poisonous. Also mercury thermometers are not allowed on aircraft.
