Sometime around he began to wander the European countryside, visiting instrument makers in Germany, Denmark, and elsewhere, learning their skills. It seems curious that Fathrenheit should have stipulated that of the subject be a man.
They contained alcohol and agreed exactly in readings. Fahrenheit also discovered the method of supercooling water—that is, cooling water to below its normal freezing point without it becoming ice. Amontons, in which he determined the boiling point of water and other liquids and studied the expansion properties of mercury.
These were the points chosen by Claus Roemer, a German scientist whom Fahrenheit visitedin Danzig [Gdansk], Poland, 24 May ; d. The Hague, Natherlands, 16 September experimental physics. Work by others showed that water boils about degrees above its freezing point.
Creation of thermometers Fahrenheit completed his first two thermometers by He lost both parents on the same day, Aug.
The lowest temperature was achieved by preparing a frigorific mixture of ice, water, and ammonium chloride a saltand waiting for it to reach equilibrium. Fahrenheit was born in Gdansk in Polish province of Royal Prussia where the Fahrenheits naturalised in Fahrenheit never married and continued to be active up to his death.
He used mercury successfully because of his method of cleaning it, and he introduced the use of cylinder-shaped bulbs instead of sphere-shaped ones. Copyright The Gale Group, Inc. These experiments led to the discovery that the boiling point of water varies with changes in the pressure of the atmosphere.
Abby Jul 29, He visited England in and was the same year elected a Fellow of the Royal Society. These experiments led to the discovery that the boiling point of water varies with changes in the pressure of the atmosphere. He soon decided to replace the alcohol with mercury and completed a series of investigations based on the work of Danish astronomer Olaus Roemer.
There he became acquainted with three of the greatest Dutch scientists of his era:The German instrument maker Gabriel Daniel Fahrenheit () made the first reliable thermometers.
The temperature scale he originated is named after him. Born in Danzig on May 14,Gabriel Fahrenheit was the son of a well-to-do merchant. The German instrument maker Gabriel Fahrenheit made the first reliable thermometers, and the temperature scale he created is named after him.
Early life Born in Danzig, Germany, on May 14,Gabriel Daniel Fahrenheit was one of Daniel and Concordia Schumann Fahrenheit's five children. Daniel Gabriel Fahrenheit, also called Gabriel Daniel Fahrenheit (May 24, - September 16, ), was a physicist and an engineer, who most of his life worked in Netherlands and for whom the Fahrenheit scale of temperature is named.
Fahrenheit invented the first truly accurate thermometer using mercury instead of alcohol and water mixtures.
In the laboratory, he used his invention todevelop the first temperature scale precise enough to become a worldwide standard. Daniel Gabriel Fahrenheit, (born May 24,Gdańsk, Pol.—died Sept.
16,The Hague, Dutch Republic [now in the Netherlands]), Polish-born Dutch physicist and maker of scientific instruments.
