網頁2024年1月23日 · Electromagnetic energy (or radiant energy) is energy from light or electromagnetic waves. Example: Any form of light has electromagnetic energy, including parts of the spectrum we can't see. Radio, gamma rays, x-rays, microwaves, and ultraviolet light are some examples of electromagnetic energy. The internal energy of a thermodynamic system is the energy contained within it, measured as the quantity of energy necessary to bring the system from its standard internal state to its present internal state of interest, accounting for the gains and losses of energy due to changes in its internal state, including … 查看更多內容 The internal energy of a system depends on its entropy S, its volume V and its number of massive particles: U(S,V,{Nj}).
