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.
- What is the clear liquid in a Galileo thermometer?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...
- How do you read a Galileo glass thermometer?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...
- How accurate is a Galileo thermometer?This thermometer is better for approximations. It closely measures ambient temperatures, but because it uses buoyant forces its calculations may no...
- Can a Galileo thermometer freeze?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...
Jan 3, 2021 · In 1593, Galileo Galilei invented a rudimentary water thermoscope, which for the first time allowed temperature variations to be measured. Today, Galileo's invention is called the Galileo Thermometer, even though by definition it was really a thermoscope.
