En 1847, el físico, James Prescott Joule enuncia el Principio de Conservación de la energía. El Principio de Conservación de la energía expresa que "la energía no se crea ni se destruye, se transforma". Esto quiere decir, que la energía puede transformarse de una forma a otra, pero la cantidad total de energía siempre permanece constante.
James Prescott Joule experimented with engines, electricity and heat throughout his life. Joule’s findings resulted in his development of the mechanical theory of heat and Joule’s law , which quantitatively describes the rate at which heat energy is produced from electric energy by the resistance in a circuit.
James Prescott Joule and energy conservation. As the son of a Manchester brewer, privately tutored for several years by the chemist John Dalton, James Joule took an early interest in all the technical equipment associated with brewing. In 1840, at the age of 22, he experimentally discovered that the heat generated in a coil of wire is ...
Primeiros anos Desenho de Joule de 1892. Filho de Benjamin Joule (1784-1858), um rico cervejeiro, Joule foi educado em casa, em Salford, até 1834 quando foi enviado, com seu irmão Benjamim, para estudar com John Dalton na Sociedade Literária e Filosófica de Manchester.
Fisico inglese tra i fondatori della moderna termodinamica, (1818 - 1889). Il fisico inglese James Prescott Joule fu tra i primi scienziati a eseguire misure accurate di cambiamenti di temperatura e di quantità di calore scambiate tra diversi sistemi termodinamici. Convinto che il calore fosse una forma di energia, Joule realizzò i famosi ...
James Prescott Joule died on October 11, 1889 in Sale, Greater Manchester, England after a long illness. He was 70 years old. James Prescott Joule studied the nature of heat and established its relationship to mechanical work. He laid the foundation for the theory of conservation of energy, which later influenced the First Law of Thermodynamics.
