### U

What does it mean by U is a state property?

### Re: U

U is a state property because changes in internal energy are functions of final and initial states

### Re: U

U is a state property because the value is determined by its current state. A state property is not dependent on the path taken to obtain that state.

### Re: U

U is a state property/function because it does not depend on the path taken to get to its present state and also describes the equilibrium state of the system. That is why you can add or subtract separate internal energies to calculate the total internal energy.

### Re: U

A state property depends on the current state of the system, as opposed to the path it took to get to that state.

### Re: U

It means that the internal energy is dependent on the initial and final states of energy.

### Re: U

This mean that internal energy depends only on the current state of the system and is independent of how that state was prepared. Other examples of state functions are pressure, volume, temperature, and density.

U is a state property because the path taken does not matter. Only the initial and final conditions matter.
