May 2, 2022 · What is a state function? I've been briefly introduced to the idea in an introductory module, and I'm confused by the whole idea, I understand the 'path dependence' from line integrals, …

Jan 22, 2020 · This is why entropy is a state function - its value does not depend on the processes required to reach that value. You can intuitively realize this by the following thought experiment: …

Feb 12, 2020 · I'm hoping that pherhaps, in answering this question, people could elaborate on his answer there. How can we show that Entropy is a state Function, if it seems that in the process of its …

Sep 6, 2023 · 2 So, I have been studying thermodynamics, in it I read that state functions are those functions which depend only on one state of the system and are independent of the path taken, …

Mar 16, 2017 · A state function is a function defined over all possible states of the system such that its value for every state does not depend on how the system reached the state.

Dec 19, 2021 · How can entropy, S, be a state function if it has different values at states 1 and 2 depending on if the process is reversible or irreversible i.e: for the entropy to be a state function …

Apr 15, 2024 · The internal energy of a thermodynamic system (which is manifestly a state function) can be changed on a microscopic level, e.g., via collisions between the molecules of the container with a …

Sep 9, 2022 · State function is a function that depends only on the thermodynamic variables characterizing a state, but not on how we arrive to this state. E.g., the internal energy is a function …

Apr 18, 2021 · Within thermodynamics, it is not possible to provide a rigorous proof that $\Delta U=q-w$ is a function of state, simply because this is the content of the first principle of thermodynamics.

Why are state functions important in physics? What does it mean, physically, that a certain variable is a state function? I know the definition of state function, but I can't figure out why it would be important …
