Fahrenheit, Daniel Gabriel (1686-1736) German Instrument maker, physicist Daniel Gabriel Fahrenheit, a German instrument maker and physicist, was born in Danzig, Germany (now Gdansk, Poland), in 1686, the oldest of five children. Fahrenheit s major contributions lay in the creation of the first accurate... [Pg.105]

The formulas for getting back and forth between the Fahrenheit and Celsius temperature scales are °F = 9/5°C + 32 and °C = 5/9(°F — 32). These temperature scales are named for their inventors, Daniel Gabriel Fahrenheit and Anders Celsius. [Pg.375]

He turned his interests from steel to temperature, and in 1730 he presented to the Paris Academy his study A Guide for the Production of Thermometers with Comparable Scales. He wanted to improve the reliability of thermometers based on the work of Guillaume Amontons, though he appears not to be familiar with Daniel Gabriel Fahrenheit s earlier work. [Pg.234]

But there is a simple way out of this dilemma. The heights of mountains are not referred to the geocenter but to the sea level (Fig. 4.3). Everyday temperatures are not referred to absolute zero, but are given as Celsius temperatures based upon the freezing point of water. (The zero point of Daniel Gabriel Fahrenheit s original scale was determined by placing the thermometer in brine, here a mixture of ice, water, and ammonium chloride.)... [Pg.101]

Daniel Gabriel Fahrenheit (1686-1736). German instrument maker. Fahrenheit invented the first practical mercury thermometer. In developing his temperature scale, Fahrenheit chose 0° to be the temperature of the coldest sample he could make in his laboratory, namely, a mixture of snow, water and ammonium chloride. The high end of his scale was chosen to make body temperature equal to 96° (more precise modern measurements give body temperature as 98.6°F). [Pg.285]

Mercury thermometer, Fahrenheit temperature scale (Daniel Gabriel Fahrenheit) Fahrenheit uses mercury in a glass thermometer to measure temperature over the entire range for liquid water. [Pg.2034]

Fahrenheit In the United States, the Fahrenheit scale is used to measure temperature. German scientist Gabriel Daniel Fahrenheit devised the scale in 1724. On the Fahrenheit scale, water freezes at 32°F and boils at212°F. [Pg.34]

Fahrenheit, Gabriel Daniel (1686-1736) German physicist and engineer but lived most of his life in the Dutch Republic in 1717, he settled in The Hague with the trade of glassblowing, making barometers, altimeters, and thermometers. From 1718 onwards, he lectured in chemistry in Amsterdam. [Pg.602]

Fahrenheit, Gabriel Daniel (1686-1736) German physicist, who became an instrument maker in Amsterdam. in 1714 he developed the mercury-in-glass thermometer, and devised a temperature scale to go with it (seeFahrenheit scale). [Pg.312]

Gabriel Daniel Fahrenheit invented the alcohol thermometer in 1709 and the mercury thermometer in 1714. [Pg.18]

The Fahrenheit scale was devised by Gabriel Daniel Fahrenheit (1686-1736), a natural philosopher who was bom in Danzig and settled in Holland. He invented the mercury thermometer in 1714 before then alcohol had been used as the liquid in thermometers. As the zero point on his scale he took the temperature produced by mixing equal quantities of snow and ammonium chloride. His choice of 212 for the boiling point of water was made in order that the temperature of his body should be 100°F The normal temperature of the human body is 98.6°F perhaps Fahrenheit had a slight fever while he was calibrating his thermometer. [Pg.16]

The temperature of a system has not always been an obvious measurable of a system, and the concept of a minimum temperature is relatively recent. In 1603, Galileo was the first to try to quantify changes in temperature with a water thermometer. Gabriel Daniel Fahrenheit devised the first widely accepted numerical temperature scale after... [Pg.2]

Fahrenheit scale A temperature scale invented in 1714 by German physicist and instrument-maker Gabriel Daniel Fahrenheit (1686-1736). Fahrenheit was the first person to make practical thermometers using mercury irrstead of spirits of wine (alcohol). He calibrated his thermometer between two fixed points for which he used the eutectic point of salt water as 0°, which was the lowest temperature he could obtain in the laboratory, and the temperature of a healthy human which he originally called 12° and later 96°. He found that on his scale, pure ice melted at 32°F and steam at normal atmospheric pressure was 212°F. The conversion to the Celsius scale is given by ... [Pg.140]

Fahrenheit scale A temperature scale in which the ice temperature is taken as 32° and the steam temperature is taken as 212° (both at standard pressure). The scale is not used for scientific purposes. To convert between degrees Fahrenheit (F) and degrees Celsius (C) the formula C/5 = (F -32)/9 is used. It is named for the German physicist Gabriel Daniel Fahrenheit (1686-1736) who proposed a scale of this type in 1714. [Pg.89]
