Explanation : In a thermodynamics , the change of state of a system from one phase into another phase is called Reversible change .
So, we can say that the reversible change that occur when a substance changes from one phase to another phase without formed a new compound.
Example : Ice
When Ice is heated then the ice melts and change its state . Now if melt ice is cooled, then it come back to ice form this process is reversible change.
