Hace 55 minutos · James Prescott Joule. Joule also famously worked on thermodynamics, investigating the connection between heat and other forms of energy. At the time, it was thought that heat could not be created or destroyed, but Joule argued that, e.g., heat and mechanical energy can be converted into one another, a concept which he also presented at the annual meeting.
Hace 5 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 5 días · James Prescott Joule vio el valor de la obra de Herapath. En 1848, leyó un artículo en la Sociedad Literaria y Filosófica de Manchester en el que trataba de revivir la teoría cinética. Este artículo, también, fue ignorado por otros científicos.
Hace 2 días · James Prescott Joule (1818-1889) Contribution: James Joule's experiments on the mechanical equivalent of heat established the principle of energy conservation and the relationship between heat and mechanical work. Impact: Joule's work led to the first law of thermodynamics and the concept that energy cannot be created or destroyed, only ...
Hace 3 días · • Origen El calentamiento resistivo fue estudiado primero por James Prescott Joule en 1841 e, independientemente, por Heinrich Lenz en 1842. Joule sumergió un trozo de alambre en una masa fija de agua y midió el aumento de temperatura causada por el paso de una corriente conocida que fluyó a través del alambre durante un período de 30 minutos.
Hace 2 días · The heating effect of electric current, also known as Joule heating, is the process by which an electric current passing through a conductor generates heat. This phenomenon was discovered by James Prescott Joule in the 19th century and is expressed by the formula: “`
Hace 4 días · The measurement of energy in the form of Joules is fundamental to physics, named after James Prescott Joule. It quantifies the amount of work done or energy transferred. The formula relating feet per second (FPS) to Joules is particularly relevant in ballistics and physics, where it's essential to understand the kinetic energy of a ...
