Hace 5 días · James Prescott Joule also claimed that there was a relationship between mechanical motion and heat, and his idea became the basis for the science of thermodynamics. In 1847, at a meeting of the British Association for the Advancement of Science, Thomson first heard Joule’s theory about the interconvertibility of heat and motion.
Hace 4 días · At that meeting, he heard James Prescott Joule making yet another of his, so far, ineffective attempts to discredit the caloric theory of heat and the theory of the heat engine built upon it by Sadi Carnot and Émile Clapeyron. Joule argued for the mutual convertibility of heat and mechanical work and for their mechanical equivalence.
Hace 1 día · The joule is named after James Prescott Joule. As with every SI unit named for a person, its symbol starts with an upper case letter (J), but when written in full, it follows the rules for capitalisation of a common noun; i.e., joule becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case.

Hace 4 días · Joule (J) 1J = 1N⋅m = 1kg⋅m²/s². The Joule is the SI unit of work, named after James Prescott Joule. It quantifies the work done or energy transferred when a force of one newton is applied to move an object one meter in the direction of the force.
Hace 5 días · A joule is a unit of energy equal to the work done by a force of one newton moving one meter; Joule was named after 18th-century scientist and mathematician, James Prescott Joule; James Prescott Joule conducted a series of experiments that demonstrated a direct relationship between heat and mechanical work
11 de abr. de 2024 · The English physicist James Prescott found that the amount of heat per second generated in a conductor carrying a current is directly proportional to the electrical resistance of the wire and the square of this passing current.
