John Dalton
John Dalton was born in September 5,1766 in Eaglesfield in Cumberland, England. Dalton and his family lived in a small country house. His family had been Quakers since 1690. Quakers where members of a society of friends. John had a brother named Mary and A brother named Charles, when he was born his brother was twelve years old and his sister was two years old. Dalton's birth was not recorded, so when he grew up older he asked one of his relatives and got and answer which was his birthday. His parents were honest people and good workers. His dad Joseph had land he had inherited were Dalton and his brother Charles help out with the crop. His mother Deborah Greenup homespun textile Dalton's sister help her too. John Dalton's family were poor but "although they were never hungry they were poor" Dalton was lucky he was a Quaker , other boys received little or no education, but as Quakers Dalton received a fair education at the closest Quaker school . For Dalton it was an achievement going to school since in those times only one out of two-hundred and fifteen people could read. John Dalton went to the Quaker school at Pardshow Hall. Dalton was quick when it came to studies and in mathematical problems he was good and seem to
John Dalton later met another man named Gough who was his new mentor. He was the son of a wealthy tradesman, and was blind. He taught Dalton languages, mathematics, and optics. Dalton dedicated to Gough two of his earliest published books to Gough who had encourage his lifelong interest in meteorology, Gough was the one that told Dalton to keep a daily journal, and he would for forty six straight years. Through his observations Dalton was the first to prove the validity of the concept that rain is precipitated by a decrease in temperature, not by a change in atmospheric pressure. Dalton once separated water into two gases, hydrogen and oxygen. He notice that the oxygen gas created was eight times heavier than the hydrogen gas . Hydrogen was known to be the lightest gas of all. The Law of Multiple Proportion was apparently developed by Dalton himself around 1804. The law of multiple proportions states that when two elements are observed to form more than one compound between them, the mass ratios in one compound will be related to the mass ratios in the other, in the proportions of the whole numbers, that means that if for example you have CO and CO2 the oxygen to carbon ratios are 16:12 and 32:12. That means that the second ration is exactly twice as the first because they are exactly twice as many oxygen's in CO2 per carbon as there are in CO. The way he did this is by decomposing. The ratios were determine by synthesizing compound from pure elements. For example when a measured amount of hydrogen was burned in excess oxygen an exact amount of water always evolved. The result of the water product was weighted, and since the hydrogen used was known, the oxygen used was determined assuming conservation of mass. In this way it was found that water contains 11.19% hydrogen and 88.81% oxygen by mass. Since it was the lightest element known, and assumed to be a fundamental value, Dalton assumed by research that hydrogen should have an atomic mass of one. In 1830 Dalton because one of the eight foreign associates of the French Academy of Sciences. And one July 27,1894 John Dalton died of normal reason. He was really old when he died. John Dalton was very smart, but he was poor, unorganized and he was colorblind, In France this condit
