The process of salt dissolving in boiling water is a physical change. In a physical change, the substance may change its state or form but its chemical composition remains the same. When salt (sodium chloride) dissolves in water, it separates into its individual ions (sodium and chloride), but the chemical structure of the salt does not change. When the water evaporates, the salt can be recovered in its original form. Thus, the dissolution of salt in water is a physical change.
