WebJan 26, 2016 · I'm sure you have heard the definition so many times before, a state variable is one that only depends on initial and final values, so a path variable is any variable that is not a state variable. Here is a trick: for state functions such as U, V, and so on, you see deltaU, deltaV, Vinitial, Vfinal. however, for path functions as such q and w ... WebThe difference between s tate and path functions has its roots deep in mathematics and it comes in as soon as a function has two of more variables. The gas law is a good example.

WebFeb 26, 2024 · The need for this analysis arises when one function needs to capture data while another needs to store it in a folder. In order to process the results and separate out the good from the bad, I must permit the folder to be created and then read the stored results using analysis scripts before making a decision. WebA state function depends only on the present state, and doesn't care about history. For example, the displacement from a reference point to an object is a state function. If you know where the reference point is, and where the object is, you know the displacement. For example, using a race track, a car at the starting line has a displacement of ...
