Detailed Solution

A picture drawn on the drawing sheet is an example of both reversible and irreversible change.
Irreversible changes are those changes that we cannot reverse once they occur. They are chemical changes, and in this change, the property of the substance changes completely, and it cannot be reverted as milk turned into curd is an example of irreversible changes.
When any substance changes, there is a change in the properties of the substance, and when it can again revert these changes, it is known as a reversible change, like the melting of ice.
When a picture is drawn on the drawing sheet, it is an example of reversible and irreversible change. It is a reversible change if it is drawn with a pencil, then we can erase it, but it is irreversible if it is drawn with a pen or sketch because it cannot be reversed or erased.
