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 3 días · The Joule-Thomson effect is a fundamental principle in thermodynamics that describes the temperature change in a real gas when it is forced through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment. This phenomenon is named after James Prescott Joule and William Thomson, ...

Hace 2 días · James Prescott Joule and William Thomson (Lord Kelvin) discovered the Joule-Thomson effect in the 1850s. How does the Joule-Thomson effect occur? The effect occurs during gas expansion or compression through a porous plug or valve without heat exchange.
Hace 2 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 4 días · Energy in thermodynamics is expressed in Joules (or kilojoules). The unit is named in honour of English physicist James Prescott Joule (1818-1889), who determined using different materials that heat was a form of energy irrespective of the type of substance being heated.
