What German scientist, who died on 16 Sept 1736, invented a temperature scale in which water boils at 212Ă¸ and absolute zero is defined as -459.67Ă¸?
Fahrenheit Fahrenheit The Fahrenheit scale is a temperature scale based on one proposed in 1724 by Dutch–German–Polish physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist. The lower defining point, 0 °F, was established as the temperature of a solution of brine made from equal parts of ice, water and salt (ammonium chloride). Further limits were established as the melting point of ice (32 °F) and his best estimate of the average human body temperature (96 °F, about 2.6 °F less than the modern value
Scale of temperature the Celsius scale are currently defined by two different points: absolute zero, and the triple point of VSMOW (specially prepared water). This definition also precisely relates the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature (symbol: K). Absolute zero, the hypothetical but unattainable temperature at which matter exhibits zero entropy, is defined as being precisely 0 K "and" −273.15 °C. The temperature value of the triple point of water is defined as being precisely 273.16 K "and" 0.01 °C. This definition fixes the magnitude of both the degree Celsius and the kelvin as
