How do you hang a Galileo thermometer?
Hang your Galileo thermometer indoors and from a hook. For the most accurate results, it’s best to not hang the thermometer in direct sunlight. Allow a few minutes for the floating spheres within the thermometer tube to rise and fall according to the current temperature.
Why Galileo thermometer is not accurate?
Explanation: the Galileo thermometer operates on the principle of buoyancy, the phenomenon by which objects of greater density than their surroundings sink and less-dense ones float. For instance, the ball marked at 78 degrees F will be just slightly less dense than tube liquid at that temperature, causing it to float.
Can you use a Galileo thermometer outdoors?
The thermometer is filled with parafin oil, which is similar to kerosene. It will NOT freeze or break. The only precaution you should worry about is making sure it is not in direct sunlight as the colors of the orbs can fade from exposure to direct sunlight.
What liquid is in a Galileo thermometer?
Hello Caroline, The liquid in AcuRite Galileo Thermometers is 100% paraffin. The colored bulbs are filled with paraffin and 3.4% dye. The liquid is non-toxic.
How old is a Galileo thermometer?
Based on a thermoscope invented by Galileo Galilei in the early 1600s, the thermometer on your co-worker’s desk is called a Galileo thermometer. A simple, fairly accurate thermometer, today it is mostly used as decoration.
How do you read a Galileo thermometer?
To read the ambient temperature on a Galileo thermometer is very easy. What you have to do is simply look at the lowest ball that is floating while ignoring those tags that had sunk to the bottom of the container. It’s those balls that float or are neutrally buoyant that interest us.
What is the clear liquid in 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, it varies depending on the temperature, even more so than water.
Can Galileo thermometers freeze?
The liquid most often in a Galileo thermometer is water, so it will freeze and bust at extremely cold temperatures.
What is a Galileo thermometer and how does it work?
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. It…

A simple, fairly accurate thermometer, today it is mostly used as decoration. The Galileo thermometer consists of a sealed glass tube that is filled with water and several floating bubbles.
What is the clear liquid inside a Galileo thermometer?
The clear liquid inside the Galileo thermometer is not water, but is another liquid, typically ethanol, whose density varies with temperature more than the density of water does. This makes it more sensitive to temperature changes which makes it a better predictor for temperature than water.
