Vanishing of a cyclic integral the property of a state function?

Click For Summary
SUMMARY

The vanishing of a cyclic integral is a fundamental property of state functions in thermodynamics. A state function is defined as a property whose integral is independent of the path taken, which leads to the conclusion that the integral over a closed loop is zero. This is demonstrated by splitting the loop into two segments: from A to B and from B back to A, where the integral from B to A negates the integral from A to B, resulting in a total of zero.

Why is the vanishing of a cyclic integral the property of a state function?
 
Physics news on Phys.org
as far as i can tell, a state function is required to be something whose integral is independent of the path chosen for the integral, this is from searchign with google, and appears to be a thermodynaics thing. if we assume this is the definition of a state function then it is clear why any integral over a loop is zero since we may split the loop into two parts and consider the loop as a path from A to B followed by a path from B to A and the integral over a path from B to A is minus the integral we get if we went along that path backwards so they must add up to zero.

if you're asking why state functions are path independent then could i have your definition of state function.
 
Thank you~ I understand now.
