12.2: The First Law of Thermodynamics - Physics LibreTexts

WebThe first law of thermodynamics asserts that energy must be conserved in any process involving the exchange of heat and work between a system and its surroundings. A machine that violated the first law would be called a perpetual motion machine of the first kind because it would manufacture its own energy out of nothing and thereby run forever. WebFirst law of thermodynamics is thus conventionally stated as: “The change in internal energy of a closed system is equal to the energy added to it in the form of heat (Q) plus the work (W) done on the system by the surroundings.”. Mathematically, this can be put as. ∆E _ {internal} internal = Q + W. golden glory yellow zucchini https://unrefinedsolutions.com
