Description
Internal-energy, U [J], can neither be destroyed nor created (first law of thermodynamics: diU/dt = 0). Note that internal (subscript i), as opposed to external (subscript e), must be distinguished from "internal-energy", U, which contrasts with "Helmholtz energy", A, as enthalpy, H, contrasts with Gibbs energy, G.
Abbreviation: U [J]
