Reading the glass thermometer (that is, determining the temperature shown) is done by holding the thermometer horizontally by the stem end (the end opposite the bulb) at eye level and rotating the thermometer until the mercury in the shaft can be clearly seen.
Similarly, how do you read a Galileo barometer?
How to read 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.
Also question is, how do you tell the temperature with a Galileo thermometer?
The temperature can be measured by reading the metal tag attached to the lowest of the floating balls in the top half of the thermometer. Galileo thermometers work on the principle of buoyancy, which determines whether objects float or sink.
How does glass thermometer work?
Liquid-in-glass thermometers are based on the principle of thermal expansion of substances. A liquid in a glass tube (called a capillary) expands when heated and contracts when cooled. A calibrated scale can then be used to read off the respective temperature that led to the corresponding thermal expansion.
What is a Galileo thermometer filled with?
Hello Caroline, 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 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.
Why is the Galileo thermometer used?
The Galileo thermometer, invented by astronomer Galileo Galilei, works mainly on the buoyancy principle. It is used to determine the capability of an object to either sink or float.
