How is a salt water mixture a physical change?
A saltwater mixture is a physical change because it involves no chemical reactions. When salt dissolves in water, the salt molecules are simply dispersed throughout the water molecules without forming new substances. This change can be reversed by evaporating the water, leaving behind the salt crystals.
