    https://en.wikipedia.org/wiki/Internal_energy

    WEBThe internal energy depends only on the internal state of the system and not on the particular choice from many possible processes by which energy may pass into or out of the system. It is a state variable, a thermodynamic potential, and an extensive property. Thermodynamics defines internal energy macroscopically, for the body as a whole.

    WEBAn energy form inherent in every system is the internal energy, which arises from the molecular state of motion of matter. The symbol U is used for the internal energy and the unit of measurement is the joules (J). Internal energy increases with rising temperature and with changes of state or phase from solid to liquid and liquid to gas.

    WEBJul 18, 2023 · The sum of all the different kinds of energy which the molecules of a substance can possess is called the internal energy and given the symbol U. (The symbol E also widely used.) In a gas we can regard the internal energy as the sum of the electronic, translational, rotational, and vibrational energies.

    WEBMar 21, 2024 · Internal energy, in thermodynamics, the property or state function that defines the energy of a substance in the absence of effects due to capillarity and external electric, magnetic, and other fields. Like any other state function, the value of the energy depends upon the state of the substance.

    WEBDec 28, 2020 · Internal energy is a measure of the total energy of a closed system of molecules, taking into account both their kinetic and potential energies. This is hard to calculate directly, but for an ideal gas, for example, there is no potential energy, so the internal energy is simply U = 3nRT/2.
