Want this question answered?
there is no property that can be observed without somehow changing the identity of the object due to Heisenberg's Uncertainty Principle.
physical properties
Physical property is an aspect of matter that can be observed or measured without changing, Chemical property may only be observed by changing the chemicals identity of a substance. (this was copied off a scientific website) :)

what property of matter has a characteristic that can be measured or observed without changing it idenity
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance.

physical properties
No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
Burning something is a chemical property. A physical property is an aspect of matter that can be measured without changing it. A chemical property may only be observed by changing the chemical identity of the substance.
Anything that has mass and occupies volume is called matter. In any substance its volume can vary but the mass is its intrinsic property. Mass of a particular substance remains the same anywhere we go but that is not the case for weight of a substance.
I believe that you are referring to physical properties. They are observed without changing composition of the substance. Physical properties are more obvious things like colour, shape, etc.
A physical property can be observed without changing the substance into something else.
B: Physical Property
A chemical property is the properties exhibited by a material in a chemical reaction. This gives a substance the ability to have a chemical identity and is also used in building chemical classifications. The properties can be used in identifying a substance that is unknown or to separate substances. The property also helps in providing information on the application of a substance.
