NettetThe earliest Fahrenheit thermometer contained alcohol, but in 1714 he developed a version of the thermometer made out of mercury while using the same scale. He determined the freezing water to be at 32°F., and its boiling point at 212°F., the human body temperature was set at 98.6°F.

Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. If it freezes it won’t move in the tube, so a liquid must be used that has a freezing point that’s lower than the temperature it’s measuring. Nettet1. jul. 2024 · If alcohol was used for this application, it would start to boil at around 78°C. The vapor pressure would rise quickly inside the capillary and in the end, the bulb will break and spoil your dinner.
