Henry Cavendish was a British philosopher, scientist, chemist and physicist. He is best known for his discovery of hydrogen or ‘inflammable air’, the density of air and the discovery of Earth’s mass. Born on October 10, 1731, in Nic to a family with the background of aristocrats.
What is Henry Cavendish known for?
Henry Cavendish (1731-1810) was an outstanding chemist and physicist . Although he was not a major figure in the history of respiratory physiology he made important discoveries concerning hydrogen, carbon dioxide, atmospheric air, and water.
What was Cavendish credited for discovering?
Henry Cavendish was a British philosopher, scientist, chemist and physicist. He is best known for his discovery of hydrogen or ‘inflammable air’, the density of air and the discovery of Earth’s mass .
When did Cavendish discover water?
Cavendish did eventually publish his findings on the formation of water in 1784 .
What was the Cavendish experiment and what was discovered?
The Cavendish experiment, performed in 1797–1798 by English scientist Henry Cavendish, was the first experiment to measure the force of gravity between masses in the laboratory and the first to yield accurate values for the gravitational constant.
How did Henry Cavendish discover the value of G and Earth’s mass?
In 1798 Cavendish measured the force between attracting lead spheres with a torsion balance . He knew the masses of the spheres and how far apart they were. He carefully measured the force between them, which allowed him to calculate G.
Why did Cavendish use the word inflammable?
Cavendish found that when metals such as zinc and iron were mixed with hydrochloric acid or dilute sulfuric acid, a flammable gas was released . He called this gas “inflammable air”. ... Cavendish knew that mixture of hydrogen and air exploded upon ignition.

What is the definition of Cavendish?

What was the major contribution of Henry Cavendish to the universal law of gravitation?
In Newton’s law of universal gravitation, the attractive force between two objects (F) is equal to G times the product of their masses (m 1 m 2 ) divided by the square of the distance between them (r 2 ); that is, F = Gm 1 m 2 /r 2 . The experiment was performed in 1797–98 by the English scientist Henry Cavendish.
Who was the first person to discover water?
Who discovered the water? It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect).
How many papers Cavendish wrote?
She was unusual in her time for publishing extensively in natural philosophy and early modern science, producing over a dozen original works; with her revised works the total came to 21 . Cavendish has been championed and criticised as a unique, ground-breaking woman writer.
Who discovered hydrogen first?
Hydrogen was discovered by the English physicist Henry Cavendish in 1766. Scientists had been producing hydrogen for years before it was recognized as an element. Written records indicate that Robert Boyle produced hydrogen gas as early as 1671 while experimenting with iron and acids.
What was the conclusion of the Cavendish Experiment?
The results of the Cavendish Experiment was the mass density of the earth, yet others were able to derive the actual value of the gravitational constant from the experiments results.
What is the value of g’on Earth?
Its value is 9.8 m/s 2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s 2 . When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth’s surface.
Who discovered the gravitational constant?
The first measurement of G was made in 1798 by Henry Cavendish , who used a torsion balance designed by John Michell to measure the constant with 1% uncertainty.
