WebOct 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 particular system. The value of a change in a state function is always the difference between the final and initial values. It is important to note that the value depends ... WebConfusion about work as a state or path function. So in physics context, energy (and thus work) is a state function and doesnt change based on the path you take to achieve the final state. But in thermodynamics, work is a path function because it is the area under the curve on PV graph. Why do works on different levels have completely different ... WebThe differential of a function that cannot be integrated cannot be defined exactly. Thus, these functions are called path functions; that is, they depend on the path rather than the state. The most typical examples of path functions that we will encounter in the next chapters are heat (\(Q\)) and work (\(W\)). help acrostic composition

WebFeb 29, 2016 · 4 Answers Sorted by: 14 Enthalpy and heat are entirely different things. Enthalpy is a function of state. If you know the state of a system, you know its enthalpy. If you know the starting and ending states of a process, you can find the enthalpy change. Heat, on the other hand, is an inexact differential. WebPath functions depend on the path taken to reach one state from another. Different routes give different quantities. Examples of path functions include work, heat and arc length.

WebPath function: Their magnitudes depend on the path followed during a process as well as the end states. Work (W), heat (Q) are path functions. Process A: W A = 10 kJ Process b: W B = 7 kJ; Point Function: They depend on the state only, and not on how a system reaches that state. All properties are point functions.

WebPath functions depend on the path taken to reach one state from another. Different routes give different quantities. Examples of path functions include work, heat and arc length. In contrast to path functions, state functions are independent of the path taken. Thermodynamic state variables are point functions, differing from path functions. WebThe amount of work being done to the two systems are not the same in the two diagrams (see the gray areas). Work is not a state, but a path function, as it depends on the path taken. You may say, what's the big difference. In both cases, the system is compressed from state 1 to state 2. The key is the word suddenly.
