  1. physical chemistry - What is the exact definition of state functions ...

    Nov 2, 2015 · A state function is a property of a system that depends only on the current equilibrium state of the system, not on the way in which the system acquired that state.

  2. thermodynamics - State functions and change in state functions ...

    Sep 6, 2023 · As state function change depends on two states, not on the current state only, it is not a state function. Multiple initial states, leading to the common final state, would mean …

  3. How can entropy of universe or surroundings be a state function?

    May 5, 2023 · A State Function has a value for a given state of a system. This means that if something undergoes a process and eventually returns to the exact same conditions as it …

  4. What are examples for state functions? - Chemistry Stack Exchange

    Oct 23, 2015 · Examples of state function include (1) internal energy, (3) volume, and (4) pressure. This is because a state function is a value in which is dependent on the state of that …

  5. Delta U is a state function? - Chemistry Stack Exchange

    Mar 1, 2022 · Although you have found a feature that satisfies a mathematical property of a state function, the feature is not sufficient to render $\Delta U$ a state function.

  6. Is delta H a state function? - Chemistry Stack Exchange

    Feb 23, 2015 · $\Delta H$ is a function of two states, the initial state and the final state. For a given final state, there can be infinite $\Delta H$ values depending upon what the inital state was.

  7. Understanding How H=U+PV is a State Function - Physics Forums

    Aug 12, 2011 · A state function describes the equilibrium state of a system. For example, internal energy, enthalpy, and entropy are state quantities because they describe quantitatively an …

  8. thermodynamics - Prove that internal energy is a state function ...

    Apr 18, 2021 · Why is it that heat and work are path functions but their sum i.e. internal energy is a state function? How is it even possible? $ΔU=q+W$

  9. Show that entropy is a state function - Physics Forums

    Jan 9, 2020 · Summary:: I'm trying to show that entropy is a state function based on an analysis of the Carnot cycle and without using advanced mathematics. I'm not satisfied with the …

  10. What is the difference between enthalpy (H) and heat (q)?
