Which of the Following Is Not a State Function

Work and heat are major examples that are not state functions. In chemistry a state function is a property of a system that depends only on current conditions not on its history.

The thermodynamic state of a system refers to the temperature pressure and quantity of substance present.

. According to the first law of thermodynamics the change in the internal energy of a system is equal to the sum of the heat. P_1V_1 P_2V_2 Volume eg. Heat q and work W are not state functions being path dependent.

State functions only depend on temperature pressure and quantity of substance and not depends on how they were reached. Among the followings work is not the state function as it is path dependent while all others are path independent so are state functions. Work and heat are the path functions.

If I want to have 1000 in my bank account I can add 200week until I have 1000 or I can add 750 one week 500 the next week and then take out 250 and Ill still have 1000. Oct 23 2015 at 1503. Byjus Asked on June 11 2016 in Chemistry.

State function - it doesnt matter the path you take to get there you will always arrive at the same spot. Heat is not a state function because it. K_P K_cRTDeltan_gas Mass eg.

For example the state function PV is proportional to the internal energy of an ideal gas but the work W is the amount of energy transferred as the system performs work. We know state functions are those which are path independent. Which of the following is not a state function.

It depends on the initial and final state of the. The thermodynamic properties which depend only on initial and final states of the system and not on how the change is brought about are called the state functions. Work can not be a state function because it is proportional to the distance an object is moved which depends on the path used to go from the initial to the final state.

Q W Q W H - TS. State functions or state variables are those which depend only on the state of the system and not on how the state was reached. Therefore Internal energy ΔE q W.

Which of the following is not a state function. Q and w are NOT state functions. It is a particular.

It is a state function because it is independent of the path. We know energy doesnt depend on the path. Which of the following is not a state function.

You have used all of these in the ideal. State functions represent quantities or properties of a thermodynamic system while non-state functions represent a process during which the state functions change. Which of the following are not state functions.

Heat volume altitude internal energy. You know plenty that you may not have identified before. If work is not a state function then heat ca not be a state function either.

I II and IIIC. V_1T_1 V_2T_2 Temperature eg. The heat transformation must be dependent on the track from the initial to the final state.

A state function is simply one that depends only on the start and end point and not the path. MCQ Online Tests 73. A function which depends only on its present condition or state specified by temperature pressure moles etc and not on the manner in which the state was reached.

It is an extensive property. Correct option is C The property whose value does not depends on path is called state function. E Is a STATE FUNCTION.

II III and IV. The parameter q is not a state function because it is dependent of the path followed by the reaction. Which of the following is not a state function.

5 rows If the answer is yes then it is not a state function and if the answer is no then the. Maharashtra State Board HSC Science General 12th Board Exam. AskIITians Faculty 300 Points.

Chemistry questions and answers. In this question we have to find the function which is path-dependent which is a function that is not a state function. Which of the following are not state functionsI Q WII Q III W IV H TSA.

Question Bank Solutions 14402. Internal energy is the measure of system energy which is the sum of potential energy and kinetic energy. A state function is the property of the system whose value depends only on the initial and final state of the system and is independent of the path.

Entropy Enthalpy and Gibbs free energy all are considered as a state function because this quantity only. Internal energy is identifiable. Major examples of state functions are internal energy entropy enthalpy free energy and Heimholtz energy.

DeltaT T_f - T_i Moles eg. Solve any question of Chemical Thermodynamics with-. Which of the following is a state function that can be accurately determined a.

Path function depends on the path followed during a process as well as the end states. Value of enthalpy internal energy and entropy depend on state and not path followed so they are state functions. Work is not state function because its value depends on path followed.
