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.
Did Galileo improve the thermometer?
The great Italian scientist Galileo may have been the first person to use a telescope to observe the heavens, helping spark the scientific revolution of the 16th century, but Galileo definitely did not invent the famous thermometer and captivating curiosity that bears his name.
Where is the best place to put 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.
What happens when 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.
Why Galileo thermometer is not very 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.
Why Galileo thermometer is not accurate?
What is the liquid in a Galileo?
ethanol
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.
What is inside glass 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.
What is the liquid in a floating 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.
What happens if my Galileo thermometer breaks?
The dye inside colored bulbs may stain fabric. 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.
Do Galileo thermometers have mercury?
No, there is no mercury in a Galileo thermometer. A Galileo thermometer consists of a vertical glass tube containing water with several different…
