WHAT IS A STATE FUNCTION?
A state function is a property of a system that is based solely on its chemical and/or physical state and not on how it acquired those states. In contrast, a path function is dependent upon the path leading from one state to another.
Real world connections: Many real-world calculations involve state functions. For example, the amount of money in a checking account is a state function: if you have $1000 and spend $300, you now have $700 regardless of how you spend the $300.
Change in altitude (∆A) is a state function. For ...
