How Does A Galileo Thermometer Work
The Galileo thermometer, invented by astronomer Galileo Galilei, works mainly on the buoyancy principle. It is used to determine the capability of an object to either sink or float. Learn how a Galileo thermometer works based on the density of a liquid and buoyant force.
Find out what liquid is used, how to read the temperature, and how accurate it is. A Galileo thermometer (or Galilean thermometer) is a thermometer containing a clear liquid and several glass vessels of varying density. The individual floats rise or fall in relation to their respective density and the density of the surrounding liquid as the temperature changes.
TL;DR: A Galileo thermometer is a clever, floating-scale device that measures temperature by showing which glass bulb floats at the current air temperature. It works using the principle of buoyancy and thermal expansion of liquids. We examine what a Galileo Thermometer is and how it works to measure air temperature, using the principles of density, buoyancy, and gravity.
Galileo thermometers are glass tubes filled with floating colorful spheres. Theyre based on Galileo Galileis invention, the thermoscope. Changing temperatures cause the colorful orbs to either sink or float inside the glass tube.
What Is A Galileo Thermometer And How Does It Work? We examine what a Galileo Thermometer is and how it works to measure air temperature, using the principles of density, buoyancy, and gravity. As the density of the liquid in the tube changes with rising and falling temperatures, the glass spheres rise or sink in relation to those changes, indicating current atmospheric temperature levels. These simple, straightforward, and lovely thermometers are as easy to read as they are to set up.
