Question

Difference between reversible and reversible changes
in short​

Answer 1

A change which cannot happen backward, that is, it cannot be reversed is called an irreversible change.

...

Difference between physical and chemical changes.

Physical changes Chemical changes

Mostly reversible changes. All are irreversible changes.

A new substance is not formed. A new substance is formed.

Answer 2

Required Differentiation:

• Any change that is reversible or temporary is called a reversible change. Reversible reactions are called reversible reactions. In this reaction, one substance is converted into another substance but no new compound is formed.

• Reversible changes in processes such as thawing, boiling, evaporation, freezing, extraction, thawing. Some examples are wax melting, ice freezing, and hot water evaporating back into the water.

                              $\sf{A + B \rightleftharpoons C + D}$

• Unlike reversible changes, irreversible changes are permanent changes. Reactors form a completely new compound and are not reversible. Heating, combustion, mixing, and powdering can cause irreversible changes.

• Cooking raw eggs is a common observable example, they cannot be converted to their original form. Another example is ash obtained by the combustion of paper or other materials.

                           A → B + C
