What were John Dalton’s other contributions to chemistry? John Dalton developed a crude method for measuring the masses of the elements in a compound . His law of multiple proportions states that when two elements form more than one compound, masses of one element that combine with a fixed mass of the other are in a ratio of small whole numbers.

- HE MADE SEVERAL REMARKABLE METEOROLOGICAL OBSERVATIONS. Dalton’s first major achievements were in meteorology, the scientific study of atmosphere. In 1793, Meteorological Observations and Essays became his first published work.
- He PUBLISHED THE FIRST EVER PAPER ON COLOUR BLINDNESS. John Dalton was colour blind and so was his elder brother Jonathan Dalton. In his 1794 paper “Extraordinary facts relating to the vision of colours” Dalton described the defect he had discovered in his own and his brother’s vision.
- JOHN DALTON DID PIONEERING WORK IN HYDROLOGY. Dalton’s 1799 paper proposed after research and estimated calculations that the quantity of rain and dew are equal to the quantity of water carried off by evaporation and by the rivers.
- HE PROVIDED GREAT NEW INSIGHTS INTO THE NATURE OF GASES. In 1802, John Dalton’s ground-breaking research, which provided great new insights on the nature of gases, was published.
Apr 2, 2014 · Dalton's experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the ...
John Dalton was born on 5 or 6 September 1766 into a Quaker family in Eaglesfield, near Cockermouth, in Cumberland, England. [3][4] His father was a weaver. [5] He received his early education from his father and from Quaker John Fletcher, who ran a private school in the nearby village of Pardshaw Hall.
By far Dalton’s most influential work in chemistry was his atomic theory. Attempts to trace precisely how Dalton developed this theory have proved futile; even Dalton’s own recollections on the subject are incomplete. He based his theory of partial pressures on the idea that only like atoms in a mixture of gases repel one another, whereas ...

Engraving of John Dalton by William Henry Worthington after a painting by William Allen, 1823. Science History Institute. In explaining the law of partial pressures to skeptical chemists of the day—including Humphry Davy —Dalton claimed that the forces of repulsion thought to cause pressure acted only between atoms of the same kind and that ...
