Experiments and Observations on Different Kinds of Air (1774–86) is a six-volume work published by 18th-century British polymath Joseph Priestley which reports a series of his experiments on "airs" or gases, most notably his discovery of the oxygen gas (which he called "dephlogisticated air").
Carl Wilhelm Scheele (German:, Swedish: [ˈɧêːlɛ]; 9 December 1742 – 21 May 1786 [2]) was a German Swedish [3] pharmaceutical chemist.. Scheele discovered oxygen (although Joseph Priestley published his findings first), and identified molybdenum, tungsten, barium, nitrogen, and chlorine, among others.
Oxygen gas is the second most common component of the Earth's atmosphere, taking up 20.8% of its volume and 23.1% of its mass (some 10 15 tonnes). [19] [70] [d] Earth is unusual among the planets of the Solar System in having such a high concentration of oxygen gas in its atmosphere: Mars (with 0.1% O 2 by volume) and Venus have much less. The O
Priestley, painted late in life by Rembrandt Peale (c. 1800) Joseph Priestley (1733–1804) was a British natural philosopher, Dissenting clergyman, political theorist, theologian, and educator. He is best known for his discovery, simultaneously with Antoine Lavoisier, of oxygen gas.
In 1774, Joseph Priestley discovered that oxygen was released by heating mercuric oxide, although he did not identify the gas as oxygen (rather, Priestley called it "dephlogisticated air," as that was the paradigm that he was working under at the time). [7]
Joseph Priestley was an 18th-century British theologian, Dissenting clergyman, natural philosopher, educator, and political theorist who published over 150 works. He is usually credited with the discovery of oxygen gas , although Carl Wilhelm Scheele and Antoine Lavoisier also have such a claim.
Joseph Priestley was an important eighteenth-century natural philosopher (and educator and minister and political theorist and philosopher). Most notably, he discovered oxygen. Because Priestley made significant contributions in so many fields, it is difficult to write a succinct article on him; it is also difficult for one editor to write the ...
