Answer:
Crystallisation
Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
Decomposition reaction
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is: AB→A+B. Most decomposition reactions require an input of energy in the form of heat, light, or electricity.Aug 9, 2020
A reversible change is one in which the substance can be recovered.
No new substances are formed in a physical change. Also, the original substance can generally be recovered again in a physical change i.e. most physical changes are reversible, as the melting of ice only includes the change in physical properties like state, shape, etc.
