Define a state function.
Solution
A state function, also known as a state variable, is a property of a system that depends only on the current state of the system, not on the way in which the system acquired that state. In other words, a state function is independent of the system's history.
For example, internal energy, enthalpy, and entropy are all state functions because they only depend on the current state of the system. If you know the current state of the system, you can calculate these quantities.
In contrast, work and heat are not state functions because they depend on the path taken to reach the current state. The amount of work done or heat transferred can vary depending on the process used to change the state of the system.
In summary, a state function is a property of a system that depends only on the current state of the system, not on the path taken to reach that state.
