A drawing sheet changes when you draw a picture on it. Can you reverse this change?
No, we cannot get a fresh drawing sheet once a picture is drawn on it with paint/ oil or water.
However, we can reverse the change, if a soft pencil is used to draw the picture by the use of an eraser.
Extra information: A change is an act or a process of becoming different.
Physical change: Physical change is the change of that matter where only the appearance or molecular arrangement of matter changes without changing its composition.
Examples: Boiling and freezing of water, melting of wax, mixing sand and grains, crumpling a paper bag, chopping wood etc.
Reversible Changes are those changes that can be reversed easily to form the 'original substance'.
Properties of reversible change:
It is a temporary change. The chemical properties of a substance are not affected by a reversible change. Most physical changes are reversible changes in nature.
For example, ice melts into water, and water freezes to form ice.
