What are reversible and irreversible processes in thermodynamics?

The reversible process is the ideal process which never occurs, while the irreversible process is the natural process that is commonly found in nature. When we tear a page from our notebooks, we cannot change this and ‘un-tear’. This is an irreversible process.

What is reversible and irreversible process give examples?

(5) An irreversible process cannot be brought back to its initial state without making a change in the surroundings. Note: As the name suggests, reversible process is the process which can be brought back to the initial process or the process which is reversible. For example: Expansion and compression of spring.

What is meant by reversible process in thermodynamics?

A reversible process is defined as a process in which the system and surroundings can be returned to the original conditions from the final state without producing any changes in the thermodynamics properties of the universe, if the process is reversed.

What is reversible process in thermodynamics class 11?

Reversible Process A thermodynamic process is reversible if the process can be turned back such that the system and surroundings return to their original states, with no other change anywhere else in the universe.

What is irreversible and reversible class 11?

Irreversible chemical reactions can occur in only one direction. The reactants can change to the products, but the products cannot change back to the reactants. Reversible chemical reactions can occur in both directions. The reactants can change to the products, and the products can also change back to the reactants.

What is meant by irreversible process?

An irreversible process can be defined as a process in which the system and the surroundings do not return to their original condition once the process is initiated.

What is reversible process Class 11?

What are reversible and irreversible changes class 6?

Reversible changes: The changes which can be brought back to its original form are known as reversible changes. For example, melting of wax and stretching of a rubber band. Irreversible changes: The changes in which the matter cannot be brought back to its original state are known as irreversible changes.

What is reversible and irreversible process in thermodynamics class 11?

In terms of thermodynamics, a reversible process is where the participants go back to its initial form by inculcating minor or negligible changes in their surroundings. Contrarily, an irreversible process is a naturally occurring phenomenon, which does not go back to its original state.

What is irreversible process in thermodynamics class 11?

Irreversible processes are those that cannot be reversed. Irreversible processes takes place at a very fast rate. Dissipative Effects.

What is reversible process Class 12?

Reversible process is process in which forward and backward reaction occurs simultaneously. Reversible reaction at equilbrium is denoted as, A⇌B. So, here if we change small amount of A then the process can move towards B (Forward reaction) or, if we change amount of B then the reaction can get reversed back to A.

What is a reversible process in thermodynamics?

A thermodynamic process (state i → state f) is said to be reversible if the process can be turned back such that both the system and the surroundings return to their original states, with no other change anywhere else in the universe. As we know, in reality, no such processes as reversible processes can exist.

What is the difference between reversible and irreversible process?

A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. An irreversible process is one in which the system and its environment cannot return together to exactly the states that they were in.

Why is a reversible process considered an ideal process?

The process can be perfectly reversible only if the changes in the process are infinitesimally small. In practical situations it is not possible to trace these extremely small changes in extremely small time, hence the reversible process is also an ideal process.

What are the characteristics of an externally reversible process?

In externally reversible process no irreversibilities occur outside the system boundaries during the process. Heat transfer between a reservoir and a system is an externally reversible process if the surface of contact between the system and reservoir is at the same temperature. Dissipative force must be absent.
