if work is not a state function and internal energy is a state function,
then why does w(adiabatic)=U is a state function?
then why does w(adiabatic)=U is a state function?
A state function is a physical property or quantity that only depends on the current state of a system, and not on how the system got to that state. In other words, it is independent of the path taken to reach that state and only depends on the initial and final states.
A path function, unlike a state function, depends on the path taken to reach a particular state. This means that the value of a path function can vary depending on the path taken, while the value of a state function remains constant for a given state.
Some examples of state functions include temperature, pressure, volume, internal energy, enthalpy, and entropy. These quantities only depend on the current state of the system and are independent of the process used to reach that state.
To determine if a physical quantity is a state function, we can use the concept of path independence. If the quantity remains constant when the system undergoes a change in state, regardless of the path taken, then it is a state function. If the quantity changes depending on the path, then it is a path function.
State functions are important because they help us understand and describe the behavior of physical systems. They allow us to make predictions about the properties of a system without having to know the exact details of how the system got to that state. State functions also play a crucial role in thermodynamics, where they are used to analyze and calculate the energy changes of a system.
