What liquid is used in Galileo thermometer?
ethanol 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, it varies depending on the temperature, even more so than water.
How did Galileo’s thermometer work?
Galileo thermometers work on the principle of buoyancy, which determines whether objects float or sink. As the temperature changes, the glass balls will either sink to the bottom (temperature rises), or float to the top (temperature falls).
How accurate is a Galileo thermometer?
There is also the minor detail that Galileo thermometers are not exactly precision instruments. A small one can have 6 degrees (F) of difference between the balls, which make for quite a measurements range of error. Even larger models have at least a couple of temperature difference between the diver globes.
Did Galileo improve the water thermometer?
The first Water Thermometer was created during the 16th century. In the year 1593, Galileo Galilei made a better Thermometer which was basically a water thermometer. This newer version was the first type of thermometer to allow variations in temperature.

Can you make a Galileo thermometer?
You can use this same principle to make your own Galilean thermometer at home. Fill the measuring bowl half full of water and write down the current volume measurement. Fill one of the watertight film canisters with sand. Place it in the bowl and check the new volume measurement.
How does a liquid thermometer work?
The way a thermometer works is an example of heating and cooling a liquid. When heated, the molecules of the liquid in the thermometer move faster, causing them to get a little further apart. This results in movement up the thermometer.
How does a Galileo thermometer work density?
Essentially, 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.
Where do you put the 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.

How do you read a Galileo liquid 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.
