A Galileo thermometer should be positioned away from windows and other sources of heating or cooling. Galileo thermometers were not invented by Galileo himself, but Galileo did discover the principle that causes the Galileo Thermometers to work – the principle that liquids change density with the temperature. A Galileo thermometer should be positioned away from windows and other sources of heating or cooling. We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free. The most important factor for accuracy is the placement of the device itself. 81. 2. The spheres are different colors just to look beautiful. 4.8 out of 5 stars 37. Shop Account Wishlist Trolley.
