Trends in Contemporary Textbooks,t of energy. This experiment has been reassembled, with the calorimeter and paddle wheel replicated from the original. The results obtained with this apparatus and with those based on the Joule experiment schemes presented in the textbooks, make it possible to clarify some aspects of the Joule experiment and improve the textbook presentations.相互影响 发表于 2025-3-25 13:07:07

Although they have in common that they defend a thesis on heat that was contrary to the science of the time, they differ in their interpretation of the experiments, namely on the nature of heat, and in the theories they developed. This diversity was mitigated when they began to appear as hharrow 发表于 2025-3-26 09:41:52
A New Concept,ew findings. Clausius resolved this issue. Thomson adhered then to the thesis that heat is motion and created the concept “mechanical energy”. This concept not only covers what was properly mechanical, but also the activity due to heat, which had become a kind of motion. This is how the term energy断言 发表于 2025-3-26 15:37:25
