An irreversible process increases the total entropy of the system and its surroundings. The second law of thermodynamics can be used to determine whether a hypothetical process is reversible or not. Intuitively, a process is reversible if there is no dissipation.
A change is called irreversible if it cannot be changed back again. In an irreversible change, new materials are always formed. Sometimes these new materials are useful to us.
In contrast to reversible changes, irreversible changes are permanent changes. Reactants react to form an entirely new compound and cannot be reversed. Heating, burning, mixing, and powdering are a few processes which cause irreversible changes.

A change is called irreversible if it cannot be changed back again. Many chemical reactions are irreversible. In a chemical reaction, new materials are always formed.
