Answer 2

No, many irreversible changes are desirable.

• Changes can be of two types in the field of chemistry and physics- reversible and irreversible.

• Reversible changes are physical changes where the shape or structure of the element changes and can be returned to its original form. It does not change the composition or structure of the substance.

• Irreversible changes are chemical changes where the inner composition of the element changes and cannot be returned to its original form. It is reversed permanently.

• Many irreversible changes are quite desirable. Burning and cooking are irreversible changes that are desirable. Without these two changes, we would not be able to survive.
