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.
Why is work path independent?
In physics, it’s important to know the difference between conservative and nonconservative forces. The work a conservative force does on an object is path-independent; the actual path taken by the object makes no difference.
Is the work done independent of 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.
What is work dependent on in thermodynamics?
In thermodynamics, the quantity of work done by a closed system on its surroundings is defined by factors strictly confined to the interface of the surroundings with the system and to the surroundings of the system, for example, an extended gravitational field in which the system sits, that is to say, to things …
Why is entropy independent of the path but heat is dependent on the path?
This means for irreversible path actual entropy change is always greater than obtained by considering irreversible heat interaction. Entropy is a state function ,this statement itself means that entropy change for a process is independent of the path taken by process.
What is an independent path?
Independent path is a path through a Decision to Decision path graph which cannot be reproduced from other paths by other methods. Advantages of Path Testing: Path testing method reduces the redundant tests. Path testing focuses on the logic of the programs. Path testing is used in test case design.
What does independent of path mean?
the property of a function for which the line integral has the same value along all curves between two specified points.
What is a path dependent function?
State Functions vs. Path Functions
| State Function | Path Function |
|---|---|
| Independent of path taken to establish property or value. | Dependent on path taken to establish property or value. |
| Can integrate using final and initial values. | Need multiple integrals and limits of integration in order to integrate. |
What is path dependent and path independent?
Independent of path taken to establish property or value. Dependent on path taken to establish property or value.
Why is entropy path independent?
The entropy is a state variable, so the entropy change should not dependent on the path between the initial and final state. That’s why we can calculate the entropy change of free expansion with an isothermal process.
Why is work done a path function in thermodynamics?
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.
