Web13 de mai. de 2024 · The internal energy is a state variable, just like the temperature or the pressure. The first law of thermodynamics defines the internal energy (E) as equal to the difference of the heat transfer (Q) into a system and the work (W) done by the system. E2 - E1 = Q - W. We have emphasized the words "into" and "by" in the definition. WebAnswer (1 of 2): That given by the First Law of Thermodynamics.
