# Why Is Internal Energy A State Function

Why Is Internal Energy A State Function. It also implies that a system can exist in different states, each with a set of clearly identifiable properties including a fixed amount of energy. Select the correct answer below:

Property of the system which depends upon only state of the system and not on the path by which achieved is called state function. It also implies that a system can exist in different states, each with a set of clearly identifiable properties including a fixed amount of energy. Internal energy depends on the quantity of the system's mass.

### Internal Energy Is A State Function Because The Internal Energy Of A System Depends Upon The State Of The System And Not Upon How The System Attains That State.

Internal energy is a function of the thermodynamic state of the system. It does not depend on the process by which the system arrived at that state. If we want to separate the different components that contributed.

### The Change In The Internal Energy \(\Left( {\Delta {\Rm{U}}} \Right)\) Depends Only Upon The Initial And Final States Of The System And Upon The Intermediate States.

E is a state function. Internal energy of a system is an extensive property. This is made up of a number of components such as translational kinetic energy of molecules, bond energy, electronic energy, intermolecular interaction energy of the constituents’ particles of the system etc.

### Change In Internal Energy As A State Function.

This is why internal energy is a state function. So work is equal to something that does not depend on path. The change in internal energy during a process depends only upon the initial state and final state while work depends on upon the path followed.

### Which Of The Following Statement Is Correct?

(a) only internal energy is a state function but not work (b) only work is a state function but not internal energy (c) both internal energy and work are state functions (d) neither internal energy nor work is state function. If the process is adiabatic, then the first law becomes du=w. That's why those quantities are state functions.

### The Internal Energy Of Ideal Gases Is A Function Of Temperature Only (Joule’s Law) And Internal Energy Of Real Gases Is A Function Of Temperature, Pressure And Volume (Temperature And Volume Being The Dominating Quantities And Effect Of Pressure Are Negligible), So It Can Be Seen That Since Internal Energy Depends On Quantities Like P, T, V Which Are State Functions, The Internal.

Internal energy is the intrinsic property of the system; In contrast, work is process quantity or path function, because its value depends on the specific transition (or path) between two equilibrium states. Both of these energy transfer processes are path dependent, however, the internal energy is a function only of the state of the system.
