GENERAL KNOWLEDGE

Detailed explanation-1: -Galileo did invent the thermoscope, also called an air thermometer, which is something completely different. A more appropriate name for the “Galilean thermometer” would be a “Florentine thermometer” as all the development work took place in Florence.

Detailed explanation-2: -In 1654, Ferdinand II de’ Medici, Grand Duke of Tuscany, produced sealed tubes with a bulb and stem that were partly filled with alcohol. This was the first thermometer to depend on the expansion and contraction of a liquid, which was independent of barometric pressure.
