{i} English name; John Dalton (1766-1844), famous English physicist and chemist who revived the atomic theory (namesake for the Dalton law of partial pressure); name of two cities in the United States
American outlaw noted for his exploits as a horse thief, train robber, and leader of the Dalton gang, which included his two brothers
English chemist and physicist who formulated atomic theory and the law of partial pressures; gave the first description of red-green color blindness (1766-1844)
A unit of mass that equals the weight of a hydrogen atom, or 1 657 x 10-24 grams 1
A unit of measurement equal to the mass of a hydrogen atom, 1 67 x 10E-24 gram/L (Avogadro's number)
An atomic mass unit A unit of mass that equals 1/12 the mass of the most abundant isotope of carbon (12C), which is assigned a mass of 12 dark line - The absence of a given wavelength or set of wavelengths in a continuum spectrum
when two elements can combine to form more than one compound then the amounts of one which combines with a fixed amount of the other will have a simple multiple relationship
U.S. outlaws. Probably born in Cass Co., Mo., they worked as cowboys in Oklahoma but by 1889 had become horse thieves. In 1890-91 they robbed gambling houses, trains, and banks. In 1892 Bob, Grat, and Emmett Dalton and two other gang members rode into Coffeyville, Kan., to rob its banks; they were recognized, and vigilante citizens killed all but Emmett, who was wounded and sent to prison for 14 years. The fourth brother, Bill, had returned to Oklahoma before the raid; he later formed his own gang, and was shot by lawmen in 1894 while playing with his daughter
{i} Dalton's law of partial pressure, physical law that says that the total pressure used by a gaseous mixture equals to the sum of the partial pressures of gases if they alone were present (Law named after the famous English physicist John Dalton)
{i} Dalton's law, physical law that says that the total pressure used by a gaseous mixture equals to the sum of the partial pressures of gases if they alone were present (Law named after the famous English physicist John Dalton)
(chemistry and physics) law stating that the pressure exerted by a mixture of gases equals the sum of the partial pressures of the gases in the mixture; the pressure of a gas in a mixture equals the pressure it would exert if it occupied the same volume alone at the same temperature
born Sept. 5 or 6, 1766, Eaglesfield, Cumberland, Eng. died July 27, 1844, Manchester British chemist and physicist. He spent most of his life in private teaching and research. His work on gases led him to state Dalton's law (see gas laws). He devised a system of chemical symbols, ascertained the relative weights of atoms, and arranged them into a table. His masterpiece of synthesis was the atomic theory the theory that each element is composed of tiny, indestructible particles called atoms that are all alike and have the same atomic weight which elevated chemistry to a quantitative science. He was also the first to describe colour blindness (1794), and his lifelong meteorological journal contains more than 200,000 observations. He is remembered as one of the fathers of modern physical science
