Is entropy change for reversible and irreversible process is same?

In a reversible process, the entropy change of the system and surroundings are equal and opposite. In an irreversible process, we generate extra entropy.

Which state function can be used to distinguish between reversible and irreversible process?

An irreversible process increases the entropy of the universe. Because entropy is a state function, the change in entropy of the system is the same, whether the process is reversible or irreversible. The second law of thermodynamics can be used to determine whether a process is reversible or not.

Does internal energy change in a reversible process?

Statement is change in internal energy of a reversible cycle is zero. Since internal energy is point function/property depends on state of system and since it return to its initial state after process it has zero change in internal energy.

Is it possible for a system to have an entropy change if it neither absorbs nor emits heat during a reversible transition What happens if the process is irreversible?

Is it possible for a system to have an entropy change if it neither absorbs nor emits heat during a reversible transition? What happens if the process is irreversible? Entropy will not change if it is a reversible transition but will change if the process is irreversible.

How does entropy change in reversible process and irreversible process?

The second law of thermodynamics states that in a reversible process, the entropy of the universe is constant, whereas in an irreversible process, such as the transfer of heat from a hot object to a cold object, the entropy of the universe increases.

How do you know if a process is irreversible?

Any process is irreversible if it involves:

1. Friction.
2. Heat transfer across a finite temperature difference.
3. Expansion when there is a finite pressure difference.
4. Mixing of difference substances under any real circumstances.
5. Anything else where work is not being maximized.

What are the differences between reversible and irreversible?

A reversible process is a change that can be retraced in a reverse (opposite) direction. An irreversible process is a change that cannot be retraced in a reverse (opposite) direction.

Is reversible work a state function?

Also, reversible expansion work is a state function because between given initial and final states, there can be only one reversible path.

Is it possible for a system to have an entropy change if it neither absorbs nor emits?

What happens to entropy during the irreversible process?

During the irreversible process the various states of the system on the path of change from initial state to final state are not in equilibrium with each other. During the irreversible process the entropy of the system increases decisively and it cannot be reduced back to its initial value.

What is an internally reversible process?

Internally reversible process. The process is internally reversible if no irreversibilities occur within the boundaries of the system. In these processes, a system undergoes through a series of equilibrium states, and when the process reverses, the system passes through exactly the same equilibrium states while returning to its initial state.

What happens to the system when it undergoes a reversible change?

In the figure above, the system has undergone a change from state 1 to state 2. The reversible process can reverse completely and there is no trace left to show that the system had undergone thermodynamic change. During the reversible process, all the changes in state that occur in the system are in thermodynamic equilibrium with each other.

What are the limitations of the irreversible process?

1) In the irreversible process the initial state of the system and surroundings cannot be restored from the final state. 2) During the irreversible process the various states of the system on the path of change from initial state to final state are not in equilibrium with each other.
