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 density of the surrounding liquid as the temperature changes.
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. It consists of glass spheres that move up and down as the temperature changes.
- The clear liquid in a Galileo thermometer is ethanol, a colorless volatile liquid with very little odor. Although its density is less than water, i...
- You can read the ambient temperature by looking at the spheres that float in the liquid. Now, read the tag that is attached to the middle bulb to g...
- This thermometer is better for approximations. It closely measures ambient temperatures, but because it uses buoyant forces its calculations may no...
- Galileo thermometers do not freeze. However, you might want to keep it away from absorbing direct sunlight. This can fade the color of the spheres...
