Physical properties, like color, density, and magnetism, can be observed or measured without changing the substance. These properties are further classified into intrinsic (independent of size, like color) and extrinsic (size-dependent, like mass). Understanding these helps identify and describe materials effectively. 00:00 What are properties? 02:56 What are physical properties? 04:42 Intrinsic & extrinsic properties 06:11 Summary Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
