How does an Archimedes thermometer work?
It is the downward force of gravity that makes this thermometer work. The basic idea is that as the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As the temperature of the water changes, it either expands or contracts, thereby changing its density.
How does Galileo barometer 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).

Daniel Gabriel Fahrenheit (1686-1736) was the German physicist who invented the alcohol thermometer in 1709, and the mercury thermometer in 1714. In 1724, he introduced the temperature scale that bears his name – Fahrenheit Scale. The Celsius temperature scale is also referred to as the “centigrade” scale.

What is thermometer short answer?
A thermometer is a tool that measures temperature — how hot or cold something is. Thermometers are used to see if you have a fever or tell you how cold it is outside. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward.
Who developed the thermometer in 1715?
From the sources we know that Beccari observed in 1715 (Beccari 1715) and took readings with other thermometers from 1723 to the last day of his life in 1766 (Scarselli 1766). In 1726 Beccari wrote that the ST readings in his logs were taken by Galeazzi (Beccari 1726).
