3 days ago · Austrian physicist Ludwig Boltzmann explained entropy as the measure of the number of possible microscopic arrangements or states of individual atoms and molecules of a system that comply with the macroscopic condition of the system.
Oct 8, 2024 · The second law of thermodynamics is a physical law based on universal empirical observation concerning heat and energy interconversions. A simple statement of the law is that heat always flows spontaneously from hotter to colder regions of matter (or 'downhill' in terms of the temperature gradient).
2 days ago · Physics Quantum theory is challenging long-standing ideas about entropy. A mathematical study finds that three definitions of what it means for entropy to increase, which have previously been ...
Oct 7, 2024 · Maxwell’s demon, hypotheticalintelligent being (or a functionally equivalent device) capable of detecting and reacting to the motions of individual molecules. It was imagined by James Clerk Maxwellin 1871, to illustrate the possibility of violating the second law of thermodynamics.
Sep 30, 2024 · First law of thermodynamics, thermodynamic relation stating that, within an isolated system, the total energy of the system is constant, even if energy has been converted from one form to another. This law is another way of stating the law of conservation of energy.
4 days ago · At the point of maximum entropy, the temperature function shows the behavior of a singularity because the slope of the entropy as a function of energy decreases to zero and then turns negative. As the subsystem's entropy reaches its maximum, its thermodynamic temperature goes to positive infinity, switching to negative infinity as the slope ...
Oct 2, 2024 · The mathematical extension of certain physical laws including quantities that do not appear as such or in an operative way in physics (for example, our notion of anti-entropy in metabolic balances, mentioned below, which extend well-known balance equations in thermodynamics by a new observable).
