Explanation:
[STC0019041]. The original thermometers were mainly imprecise, measuring temperature with substances such as water (Galileo Galilei’s thermometer, 1593) and alcohol (Grand Duke Ferdinand II’s thermometer, 1654). The introduction of the mercury thermometer in 1714 revolutionized thermometer accuracy. Daniel Gabriel Fahrenheit, a German physicist, proposed putting mercury inside the thermometer to respond more accurately to temperature variations. The poisonous ingredient, while beneficial, has now been substituted in modern electronic thermometers.
