Vor 2 Tagen · 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.

Vor 2 Tagen · 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.
Vor 3 Tagen · The Lennard-Jones potential is a simplified model that yet describes the essential features of interactions between simple atoms and molecules: Two interacting particles repel each other at very close distance, attract each other at moderate distance, and eventually stop interacting at infinite distance, as shown in Figure 1.
Hello smart people! I am currently learning thermodynamics and I am having difficulty understanding why did James Prescott Joule assume that in his paddlewheel experiment the amount of mechanical energy lost in the system formed by the two weights was only proportional to the heat and not equal to it.

Vor 2 Tagen · Satuan si energi listrik – Dalam dunia kelistrikan, pengukuran energi memainkan peran penting, dan satuan SI untuk energi listrik adalah Joule. Joule, dinamai menurut fisikawan James Prescott Joule, mengukur jumlah kerja yang dilakukan atau energi yang ditransfer dalam proses listrik. Selain Joule, satuan energi listrik lainnya yang umum digunakan adalah Kilojoule (kJ) dan Watt-jam (Wh). […]
