Maxwell demon second law of thermodynamics
WebMaxwell's demon is an 1867 thought experiment by the Scottish physicist James Clerk Maxwell, ... He will thus, without expenditure of work, raise the temperature of B and lower that of A, in contradiction to the second law of thermodynamics. In other words, Maxwell imagines two containers, A and B. WebThus, opposite to what the authors claim, their data fully confirm the validity of the second law. This insight in the meaning of the second law goes back to Maxwell, who invented …

Web3 apr. 2024 · Physicist James Clerk Maxwell created a thought experiment in 1867. His idea involved a fantastical “finite being” able to sort molecules of a gas. Rarified acuity and dexterity, indeed! The topic was a hypothetical violation of the second law of thermodynamics (regarding entropy of isolated systems). His marvel became known as … WebMaxwell’s demon, second law of thermodynamics, irreversibility. Statistical thermodynamics predicts the final state a system reaches from a given initial state under given conditions with a specific maximum value. The second law’s standing among natural laws is such that, aside perhaps from the standard conservation laws, no other physical ...
WebThe framework allows us to prove the First and Second laws of thermodynamics, but also lets us apply results from optimal and stochastic control theory to physical systems. In particular, we show how to use linear control theory to optimally extract work from a single heat source over a finite time interval in the manner of Maxwell’s demon.
