Thee First Sealad Termometers ande thee Birth of Scales

In 1654, Ferdinando II de aid; Medici, Grand Duke of Tuscany, creatd a sealed alcol-in- glass thermometer that used a graducated scale. His device is widelle considered thee first modern thermometer because it was incorporate of air sure sure and could provide expreciplemente.
The Fahrenheid Scale
Daniel Gabriel Fahrenheit, a German- Dutch physilt andd instrument maker born in 1686, revolutizized temporature in thee early 18th century. After years of experimentation witch different thermometric liquids, Fahrenhelt developed the first reliable mercury thermometer in 1714. Mercury was an inspirired choice: it expands threly with temperature, means liquid over a wide range (from -38.3 ° C to 356.73 ° C), and doet wet thle glas.
Fahrenheid also devised a temperatur scale based on three fixed points. He set 0 ° F as thee coldect temporature he could accesse using a mixture of ice, water, and amorium hurium chloride (a brine). He set 32 ° F as thee freezing point of pure e water andd originally set 96 ° F ais average human body temperature (later refrifed to 98.6 ° F).

Réaumur and Celsius Scales
Around thee same time, French ch physiist René Antoine Ferchault de Réaumur proposed an color- based thermometer with a scale where the freezing point of water es 0 degrees ande boiling point was 80 degrees. Réaumur chose congrel because of its high expression coefficient, and he despect his scale by divideng the volume change between freezing and boiling intro 80 equail parts.

In 1742, Swedish astronomér Anders Celsius introdue a scale that plated thee freezing point at 0 ° C ante thee boiling point at 100 ° C. Interesingly, Celsius initially use 0 ° C as thee boiling point andd 100 ° C as the freezing point - the reverse of thee modern convention.
