## What is always equal to zero in a cyclic process?

Solution. The change in energy in a cyclic process is zero, since the initial and final states are the same.

## What would be the change in a state function in a cyclic process?

Hence, the change in a state function will be zero in a cyclic process. The change in any state function depends only on the initial and the final states of the system. hence, for both a reversible and an irreversible cyclic process, the change in any state function will be zero.

Is change in entropy 0 for a cyclic process?

No. For a cyclic process, the system returns to its original state at the end of the process, so its entropy change is zero. But for the surroundings, that are typically envisioned as being comprised of ideal reservoirs, the entropy change is not necessarily zero.

### Can work done be zero in a cyclic process?

Yes, work done in a cyclic process can be zero. When the processes reverse exactly under similar conditions retracting the samw P-V diagram.

### Why in a cyclic process the change in internal energy is always zero?

Independent of the heat given to the system. The cyclic process is the process which has the same initial and the final state of the system. So, the energy of the system in its initial and final position is the same. So, the internal energy of the system is zero.

What is not zero in cyclic process?

W=0 is not true for cyclic process. Hence, the work done by the system in a cyclic transformation is equal to the heat absorbed by the system. An example of such a system is a refrigerator or air conditioner.

## Why change in state function is not a state function?

State functions are specific for a state. For a given state they will have a definite value which is a characteristic of that state. Enthalpy change is defined for two different states, so it is not a state function.

## What is cyclic process what is change in internal energy of the system in a cyclic process?

But in a cyclic process, the total change in the internal energy of the system is equal to zero. In a cyclic process, the initial and the final state of the system are the same therefore the net change in the internal energy of the system is zero.

What is the change in entropy of a substance in a cyclic process?

In Cyclic process Change in Entropy of the system is zero.

### What happens in a cyclic process?

What Is Cyclic Process? The process in which the initial and final state is the same is known as a cyclic process. It is a sequence of processes that leave the system in the same state in which it started.

### What is cyclic process What is the change in internal energy?

In a cyclic process, initial and final states are same. Internal energy is a state function, therefore change in internal energy is zero.

In which of the following process q is zero?

Isochoric process: It is a thermodynamic process which takes place at constant volume. In such a process, the work done is zero. The volume of the gas remains constant.

## Why is work not a state function in cyclic motion?

Originally Answered: For a cyclic process change in a state function has to be zero, & in a cyclic motion change in work is zero, then why is work not a state function? I a cyclic process, the initial and the final states are the same.So, the work done in each stage of the process will also b the same.

## Is the change in internal energy zero during cyclic process?

Yes, during cyclic process, change in internal energy is zero, and no work is said to have done., As system returns to the initial state. Study economics for business with MIT.

What is the law of thermodynamics for cyclic processes?

In a cyclic process, since the system returns to its initial state, the change in internal energy must be zero. Therefore, by first law of thermodynamics, the net heat given to the system must be equal to the net work done by the system. What is a cyclic device?

### Why is q = w for a cyclic process?

This is not a coincidence: The first law requires that Q = W for a cyclic process. The change in energy in a cyclic process is zero, since the initial and final states are the same. The work done and the quantity of heat gained in such a process are therefore the same with opposite signs (R = – Q ).
