2. Thermoscope - Wikipedia

   en.wikipedia.org/wiki/Thermoscope

   Large thermoscopes placed outdoors appeared to cause perpetual motion of contained water, and these were therefore sometimes called perpetuum mobile. [3] Galileo's own work with the thermoscope led him to develop an essentially atomistic conception of heat, published in his book Il Saggiatore in 1623. [3]

3. Galileo thermometer - Wikipedia

   en.wikipedia.org/wiki/Galileo_thermometer

   A Celsius Galilean thermometer in two degree gradations. A risen orange orb denotes 24 °C. 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 density. The individual floats rise or fall in proportion to their respective density and the ...

   1709 — Daniel Gabriel Fahrenheit constructed alcohol thermometers which were reproducible (i.e. two would give the same temperature) 1714 — Daniel Gabriel Fahrenheit invents the mercury-in-glass thermometer giving much greater precision (4 x that of Rømer). Using Rømer's zero point and an upper point of blood temperature, he adjusted the ...

   Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer. Another type of thermometer that is not really used much in practice, but is important from a theoretical standpoint, is the gas thermometer .
