Mar 16, 2017 · Entropy is surely a state function which only depends on your start and end states, and the change in entropy between two states is defined by integrating infinitesimal change in entropy along a reversible path.

- How can we show that Entropy is a State Function?
From a macroscopic perspective, in classical thermodynamics the entropy is interpreted as 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.
Entropy, like internal energy, is a state function. This means that when a system makes a transition from one state into another, the change in entropy \(\Delta S\) is independent of path and depends only on the thermodynamic variables of the two states.
A measure of the disorder of a system is its entropy (S), a state function whose value increases with an increase in the number of available microstates. A reversible process is one for which all intermediate states between extremes are equilibrium states; it can change direction at any time.
Feb 12, 2020 · For $A$ being another state, let us define a function $$ S(A) = \int_O^A \frac{\delta Q}{T}$$ where the integration is performed over any curve linking state O to state A (as w ehave proven, it doesn't matter which one). This is what we called entropy. By construction, it's a function of state.
Aug 23, 2023 · Entropy (S) is a state function that can be related to the number of microstates for a system (the number of ways the system can be arranged) and to the ratio of reversible heat to kelvin temperature.…
Entropy, \(S\), is a state function, so it does not depend on the thermodynamic path. We can take any path we want to calculate the entropy of a thermodynamic system.
