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).
Just so, did Galileo invent the thermometer?
Galileo Galilei is often claimed to be the inventor of the thermometer. However the instrument he invented could not strictly be called a thermometer: to be a thermometer an instrument must measure temperature differences; Galileo’s instrument did not do this, but merely indicated temperature differences.
People also ask, how did Galileo invent the thermometer?
In 1593, Galileo Galilei invented a rudimentary water thermoscope, which for the first time allowed temperature variations to be measured. … It was perhaps the first crude clinical thermometer, as it was designed to be placed in a patient’s mouth for temperature taking.
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.
How do you use Galileo?
How does a floating bulb thermometer work?
When temperature rises, the liquid inside the glass thermometer tube becomes less dense and the liquid-filled bulbs will sink. When the temperature drops, the liquid inside the tube becomes denser and the liquid-filled bulbs will float.

Is it illegal to have a mercury thermometer?
Those days have passed. Since 2001, 20 states have banned mercury “fever thermometers” for medical use, and regulations tighten every year. … But as of today the federal government has more or less killed the mercury thermometer in the United States—NIST has announced it will no longer calibrate mercury thermometers.
What is a Galileo thermometer used for?
A Galilean thermometer is a device for measuring the temperature of a liquid based on the density variation with temperature. It is named after Galileo Galilei, the famous Italian physicist, who apparently invented it.
What is the 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. The dye inside colored bulbs may stain fabric.
What is the largest Galileo thermometer?
What is the normal temperature of a healthy person?
Where should a Galileo thermometer be placed?
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.
