If we take certain amount of ice and we start it heating we will slowly begin to observe that the ice is melting and it is turning to water.
This process is called melting and it is reversible.This is because when ice has turned to water after heating,when we place the same melted water and begin to freeze it,we will find that it is slowly being converted into ice.Hence,proving that melting of ice is a reversible process!

Reversible Change: Melting of Ice
Reversible changes are those changes that can be reversed and the original substance can be obtained back. Melting of ice is a reversible change as it can be reversed by freezing the water again. Let us understand this in detail:
Melting of Ice
When ice is heated, it melts and converts into water. This is a physical change as the chemical composition of ice remains the same. The temperature at which ice melts is 0°C. When ice melts, it absorbs heat from the surroundings and the temperature of the surroundings decreases.
Freezing of Water
When water is cooled, it freezes and converts into ice. This is also a physical change as the chemical composition of water remains the same. The temperature at which water freezes is 0°C. When water freezes, it releases heat to the surroundings and the temperature of the surroundings increases.
Conclusion
Melting of ice and freezing of water are reversible changes as they can be reversed by changing the temperature of the substance. Hence, melting of ice is a reversible change.

Because when we melt the ice it becomes liquid and when we cool the ice water it again becomes solid and reversible change means a change in which substances can come back to its original form.
