WebAlternatively you could reason using the formula: d U = d Q − d W (using your notation conventions, were U is internal energy, W is work and Q is heat added to the system) d W = P d V. Therefore. d U = d Q − P d V. Therefore if d V (change in volume) is positive, d U (change in internal energy) is negative. Share.

WebThis phenomenon is explained by the second law of thermodynamics, which relies on a concept known as entropy. Entropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work. The more disordered a system and higher the entropy, the less of a system's energy is available to do work. WebThe first law of thermodynamics can be captured in the following equation, which states that the energy of the universe is constant. Energy can be transferred from the system to its surroundings, or vice versa, but it can't be created or destroyed. First Law of Thermodynamics: Euniv = Esys + Esurr = 0.
