Does work depend on path in thermodynamics?

E does not depend on the path used to go from the initial to the final state, but the amount of work does depend on the path used, the amount of heat given off or absorbed must depend on the path.

How do you prove work is a path function?

A quantity is said to be state function only when its value depends on the initial and final state, regardless of the path it has followed. But work done is not such quantity. It does depend on the path taken from going state 1 to state 2. So, work done is a path function.

Does work done depend upon the path?

The work done by a conservative force is independent of the path; in other words, the work done by a conservative force is the same for any path connecting two points: The work done by a non-conservative force depends on the path taken.

Why work done is a path function?

Heat and work are forms of energy that are in motion. They exist only when there is a change in the state of system and surroundings. In other words, they are non-existent before and after the change of state. Therefore, the work done is a path function.

On what factors work depends?

Answer: The work done on a body depends upon two factors: Magnitude of the force (F), and. The displacement through which the body moves (s).

What is path dependence path dependence is where?

Path dependency is a phenomenon whereby history matters; what has occurred in the past persists because of resistance to change. The resistance to change could be based on the financial implications or because policymakers are making cautious or uninformed decisions.

What are the path functions in thermodynamics?

A Path function is a function whose value depends on the path followed by the thermodynamic process irrespective of the initial and final states of the process. An example of path function is work done in a thermodynamic process.

Does work done depend on initial and final position?

A conservative force acting on a system is the force when work done depends upon initial and final position only i.e. the work done is path independent.

In which process work does not depend on path?

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 the process is adiabatic, then the First Law becomes DU=W. So work is equal to something that does not depend on path.

On which factors work done depends how they affect work?

Work done by a force depends on (i) magnitude of force (ii) magnitude of displacement (iii) angle between force applied and displacement .

What factors affect work explain physics?

Work is directly proportional to the first two factors: force and displacement.

Why is path dependence important?

Path dependence is often used in studies based on the historical-institutionalist approach to political science, which focuses on how institutions come to constrain organizational life. It has become a key concept in explanations of why institutions in political life do not change as much as might be expected.

What is the path of a thermodynamic system?

When a thermodynamic system changes from an initial state to a final state, it passes through a series of intermediate states. We call this series of states a path. There are always infinitely many different possibilities for these intermediate states.

What is the first law of thermodynamics and the work done?

The first law of thermodynamics and the work can then be expressed as: The work done by the system depends not only on the initial and final states, but also on the intermediate states—that is, on the path. When a thermodynamic system changes from an initial state to a final state, it passes through a series of intermediate states.

How do you determine the internal energy of a thermodynamic system?

Suppose you have a thermodynamic system in a state A. In this state it has a certain amount of internal energy, U A, because internal energy is a state variable. You can determine the internal energy by knowing only the state. Now suppose the system undergoes some process – you don’t know (or care) what – that leaves it in state B.

Is heat a path function or a state function?

Therefore we can say that heat is path function not the state function. At the microlevel, if you were to keep track of all the degrees of freedom of the system, then all of the internal energy change would be accounted for as work, and heat exchange would always equal zero for any process.
