16 wrz 2024 · The internal energy of a substance is defined as: The sum of the randomly distributed kinetic and potential energies of the particles in a body. This means internal energy is the total of all the kinetic energies plus the total of all of the potential energies. The symbol for internal energy is U, with units of joules (J)
