who discovered thermometer?

Answers:
Galileo??The thermometer was invented by Galileo Galilei in 1593. His thermometer consisted of water in a glass bulb; the water moved up and down the bulb as the temperature changed.
The sealed thermometer was invented in 1641 by the Grand Duke Ferdinand II. He used a glass tube containing alcohol, which freezes well below the freezing point of water (alcohol freezes at -175掳F=-115掳C). He sealed the tube to exclude the influence of air pressure. Mercury was later substituted for the alcohol, and then Daniel Gabriel Fahrenheit (1686-1736), a German physicist, used mercury plus a chemical solution that kept the mercury from sticking to the tube of the thermometer (in 1714). Fahrenheit also expanded the thermometer's scale (in 1724); on his scale, the temperature of boiling water is 212掳F and the freezing point of water is 32掳F.

The first recorded thermometer was produced by the Italian, Santorio Santorio (1561-1636) who was one of a group of Venetian scientists working at the end of the Sixteenth Century. As with many inventions the thermometer came about through the work of many scientists and was improved upon by many others.The first mercury thermometer
Gabriel Fahrenheit (1686-1736) was the first person to make a thermometer using mercury. The more predictable expansion of mercury combined with improved glassworking techniques led to a much more accurate thermometer.

Just as an addition to what Highlander said, the thermometer wasn't discovered, but rather invented.

well the thermometer was not discovered it was invented! the person who invented it was Louis Ther Mometer! Hince the thermometer!
