How does the Galileo 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.
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.
How do you read a thermometer correctly?
Most thermometers have two scales for temperature, Fahrenheit and Celsius. Read the numbers for °F (degrees of Fahrenheit). Each long line is for 1°F temperature. The four shorter lines between each long line are for 0.2°F (two tenths) of a degree of temperature.
How do you read a float 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 a Galileo thermometer?
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 do you read a glass water 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 read a glass water barometer?
Luckily, it's also simple to read. To determine the likely weather, you have only to see how high or low the water is in the glass. Look at the water in the spout of the barometer. If the water holds steady around the middle of the spout, you'll have good weather.

What are the different liquids in a Galileo thermometer?
This thermometer is based on an invention of Galileo Galilei. The liquid in a Galileo thermometer is water. Floating in the water within the tube are glass bubbles also filled with water containing simple food coloring, though sometimes alcohol might be used.

The liquid in a Galileo thermometer is water. Floating in the water within the tube are glass bubbles also filled with water containing simple food coloring, though sometimes alcohol might be used. The Galileo thermometer is an accurately functioning machine that is more often than not used today as decoration.
What is a normal forehead temperature?
While typically 98.6°F (37.0°C) is considered a “normal” temperature, some studies have shown that "normal" body temperature can be within a wide range, from 97°F (36.1°C) to 99°F (37.2°C). Before NCITs are used, it is important to understand the benefits, limitations, and proper use of these thermometers.
