Reversible Change. Water in its solid state is called ice. When ice is heated, it melts and becomes liquid water. Further heating causes the liquid to change to a gas, called water vapor. When water vapor is cooled, it changes back to liquid water. Correspondingly, what is reversible and irreversible change give example? Reversible changes are changes which can be reversed by a change in conditions. Examples: Melting of ice and freezing of water. ii. Irreversible changes are changes which cannot be reversed by a change in conditions. Example: Burning of magnesium.

Accordingly, what are reversible and irreversible changes class 6? Reversible changes: The changes which can be brought back to its original form are known as reversible changes. For example, melting of wax and stretching of a rubber band. Irreversible changes: The changes in which the matter cannot be brought back to its original state are known as irreversible changes.
