How do you read the temperature on 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.
Is a Galileo thermometer accurate?
A Galileo thermometer contains colorful glass bubbles that float in a liquid. As the temperature of the liquid rises, the balls rise, too. Each bubble has a weighted tag at the bottom to indicate different temperatures. They tend to be accurate, which makes them not only decorative, but useful.
Can you calibrate a Galileo thermometer?
The Galileo thermometer consists of a sealed glass tube that is filled with water and several floating bubbles. The bubbles are glass spheres filled with a colored liquid mixture. Attached to each bubble is a little metal tag that indicates a temperature. These metal tags are calibrated counterweights.

What liquid is in Galileo thermometer?
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.
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.
What happens if a Galileo thermometer breaks?
If the thermometer breaks, clean the area with warm, soapy water. 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.
What is the liquid inside thermometer called?
mercury thermometer
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
