What is the difference between path function and state function?

state function did not depend on the path , it depends on the initial and final point of the system where as path function depends on the path of the reaction.


Is the distance traveled a state function or path function?

Its a path function......but DISPLACEMENT is a state function.Distance depends on the path we followed from one state to another but displacement is a straight distance so it depends upon the states.

Does entropy depend on its path?

No, entropy is a state function.


What is difference between path function and point function in thermodyanaMICS?

Path function: Their magnitudes depend on the path followed during a process as well as the end states. Work (W), heat (Q) are path functions.The cyclic integral of a path function is non-zero. work and heat are path functions.Point Function: They depend on the state only, and not on how a system reaches that state. All properties are point functions.The cyclic integral of a point function is zero. properties are point functions, (ie pressure,volume,temperature and entropy).


How heat is a path function?

Heat capacity is NOT a path function. It is a STATE function. It depends on the phase of the material, the temperature and the pressure. Usually heat capacity is known at some particular condition and then a calculation is required to estimate it at the condition of interest. Performing these calculations should always result in the same final value no matter the path you took to get to the value - hence it is a STATE function rather than PATH. Path functions would be things like WORK and HEAT (for which the state function "heat capacity" might be used in the calculations)

What is Path coverage in software testing?

path coverage is one of the metrics used in white box testing to check whether each of the possible paths in each function have been followed.A path is a unique sequence of branches from the function entry to the exit.


Define point function and path function?

Point function and path function are found in Thermodynamics.


What is path function in thermodynamics?

a function whose magnitude depends on the path followed by the function and on the end points.


Where will you use ampere circuital law in preference to biot savart law?

Depends on whether a path integral or a normal integral is easier to determine.


What are path functions?

a function whose magnitude depends on the path followed by the function and on the end points.
