True or false in a physical change, the substance doesn't change its identity

Sagot :


A physical change are changes which alters a substance without changing its composition. So physical means without changing its substances. For example if we changed a persons appearances it would be a physical change, but that doesn't change who they are as a person or their identity. So, true.
