Mercury thermometer mounted on a brass plate and housed in a lined wooden case. This fairly accurate instrument is based on the thermoscope invented by Galileo Galilei in the early 17th century. Mercury also has a high coefficient of expansion, but it is not too high. The individual floats rise or fall in proportion to their respective density and the density of the surrounding liquid as the temperature changes. The amount of water is related to the size of the bulb to help control its buoyancy. Each glass ball in the thermometer is filled with a liquid and attached to a metal weight with a numerical value. If there are any broken pieces of glass or sharp objects, pick them up with care. Now mind you, the tags on Galileo Thermometers tend to be numbers carved into brass.

They come in digital or analogue varieties. There are liquid-in-glass thermometers that contain a non-mercury silver substance (Galinstan ®) that, according to its maker, is not toxic when swallowed because it passes through the digestive system without effect. You can hang the thermometer inside or outside. There are a number of different types of outdoor thermometers available, so you can find one that suits your needs. Because of alcohol’s high coefficient of expansion, mercury was chosen as a better candidate for filling thermometers. A Galileo thermometer is a very simple and surprisingly accurate thermometer named after Galileo Galilei, a noted 16th century scientist.While these thermometers are primarily kept around as novelty items, they can also be utilized as functional measures of the temperature. Wes Simons started writing professionally in 2008 and has been published in Western Washington University's "The Planet," "The Seattle Business Magazine" and "Seattle Magazine." No, there is no mercury in a Galileo thermometer. It is named after Galileo Galilei because he discovered the principle on which this thermometer is based—that the density of a liquid changes in proportion to its temperature. Become a Study.com member to unlock this A thermometer tube interior cross-section is quite small … usually about 1/8 inch or less (the curvature of the glass has a magnifying effect, making the mercury column seem bigger than it actually is). answer! Rather, the different colors of the floating bubbles make for easier identification and a more pleasant aesthetic. The most basic Galileo thermometers are simple glass tubes, but some may include barometers, hygrometers, or quartz clocks.
