Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
A physical changeÊis what it'sÊcalled when an object is changed physicallyÊwithout changing the type of matter of the object. The matter can also be changed without noticing a change in the physical form as well.
