Is work a path function?

Is work a path function?

So, work is a path function as different routes give different quantities. The specific volume of a substance can be defined as the ratio of the substance’s volume to its mass. It does not depend on that path taken as it is measured for a state and not a route. Hence, the correct answer is that work is a path function.

Does adiabatic work depend on Path?

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.

Is work traveled a path function?

The functions work, heat and distance travelled do not depend on initial and final states of the system but they depend on path followed between initial and final states. So, these functions depend on the path taken to reach a specific value.

What is the function of adiabatic process?

In thermodynamics, an adiabatic process (Greek: adiábatos, “impassable”) is a type of thermodynamic process that occurs without transferring heat or mass between the thermodynamic system and its environment. Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work.

Which of the following is not a path function?

Therefore the kinetic energy is also the path function. Thermal conductivity is not a path function.

In which process work does not act as path function?

As, we know the property or a function which does not depend on the path is called a state function. Work-done in adiabatic processes is equal to the negative of change in internal energy from the first law of thermodynamics.

Which process doesn’t work depend on Path?

A state function is a property whose value does not depend on the path taken to reach that specific value.

Is adiabatic process independent of path?

In adiabatic process work is independent of path.

What are the path functions?

Path functions are properties or quantities whose values depend on the transition of a system from the initial state to the final state. The two most common path functions are heat and work.

What are examples of path functions?

Two examples of path functions are heat and work. These cannot be defined for a state (you cannot say a system has an amount of work at a specific set of conditions, only that it does a certain amount of work to get from one state to another, via a specified path).

Which is not an adiabatic process?

Which one is not an example of adiabatic process? refrigerator has compressor that blows out the heat outside.so it can not be an adiabatic process.

What is an example of an adiabatic process?

An example of an adiabatic process is the vertical flow of air in the atmosphere; air expands and cools as it rises, and contracts and grows warmer as it descends. Another example is when an interstellar gas cloud expands or contracts. Adiabatic changes are usually accompanied by changes in temperature.

What is the work done in adiabatic process between two end States?

So, the work done in an adiabatic process between two given end states depends on end states only. for an adiabatic process δQ = 0. Since, work done is equal to change in internal energy and internal energy is a point function or state function. So, the work done in an adiabatic process between two given end states depends on end states only.

Is work a path function in adiabatic expansion?

But there is only one reversible adiabatic path. The temperature difference depends on the adiabatic path. For example, an adiabatic free expansion (P=0) does no work, so there is no temperature change. For the reversible adiabatic path the temperature change is: So you are right that Work is a path function.

Why are adiabatic processes said to be isentropic?

Since in an adiabatic process, the heat transfer is zero which means the change in entropy is also zero. That’s why the process is said to be isentropic by nature. Expansion of steam in steam turbines.

Is the work done the same along all adiabatic curves?

It is said that the work done between 2 isothermals is independent of the adiabatic. From the above equation it is clear that W depends only on the initial and final temperatures. So W is the same along any adiabatic curve. But work is a path function. Then the work done along different adiabatic curves should be different.
