A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying densities. As temperature changes, the individual floats rise or fall proportion to their respective density.
It is named after Galileo Galilei because he discovered the principle on which this thermometer is basedâ€”that the density of a liquid changes in proportion to its temperatureâ€”and invented a thermoscope based on this principle.
