WHAT are reversible and irreversible change?

Question

Answer

Its not a correct answer according to 2 law of thermo Dy. entropy of universe will decide the reversible or irreversible of the process
whenever the entropy of universe is ∆s>0 process or cycle is irreversible and ∆s=0 then process is reversible also whenever ∆s <0 then='' process='' or='' cycle='' is='' impossible='' then='' process='' or='' cycle='' is=''>

Answer

A change that can be reversed in original substance is called reversible change

Answer

Reversible and Irreversible Changes
Reversible and irreversible changes are two types of transformations that occur in matter. These changes have distinct characteristics and outcomes.

Reversible Changes:
- Reversible changes are changes that can be undone or reversed.
- These changes do not alter the chemical composition of the substance.
- Examples of reversible changes include melting of ice, boiling of water, and dissolving sugar in water.
- Reversible changes are usually physical changes that can be easily observed and reversed by applying appropriate conditions.
- Energy changes may occur during reversible changes, but the original substance can be recovered.

Irreversible Changes:
- Irreversible changes are changes that cannot be undone or reversed.
- These changes permanently alter the chemical composition of the substance.
- Examples of irreversible changes include burning of wood, rusting of iron, and cooking an egg.
- Irreversible changes often involve a chemical reaction that results in the formation of new substances.
- Energy changes may occur during irreversible changes, and the original substance cannot be recovered.
In summary, reversible changes are temporary and can be reversed without altering the chemical composition of the substance, while irreversible changes are permanent and result in a new chemical composition. Understanding the difference between reversible and irreversible changes is crucial in various scientific fields, including chemistry and physics.
