Is entropy a property

WebIn general, specific entropy is a property of a substance, like pressure, temperature, and volume, but it cannot be measured directly. Normally, the entropy of a substance is given for some reference value. WebNov 19, 2024 · Entropy as an intrinsic property of matter Ask Question Asked 3 years, 4 months ago Modified 3 years, 4 months ago Viewed 308 times 2 I would like to ask how we can see entropy as an intrinsic property of molecules, namely as something depending also on their geometry (and not only as gross disorder).

WebFrom a macroscopic perspective, in classical thermodynamics, the entropy is a state function of a thermodynamic system: that is, a property depending only on the current state of the system, independent of how that state came to be achieved. WebThe usual "proof" entropy is a state property is like that: "Consider a system which undergoes a reversible process from state 1 to state 2 along path A, and let cycle be …

WebJun 13, 2024 · Since entropy is a state function, ΔS = 0 for one cycle of the machine. If the machine works (that is, ∼ MSL is true), then the entropy-based statement requires that ΔSuniverse = ΔS + ΔˆS ≥ 0. Since ΔS = 0, it follows that ΔˆS ≥ 0.
