can density always correctly identify a substance
Only in some simple situations; with more characteristics determined the identification is more sure.
state of matter for example,you cannot say a liquid is water because it is liquid,so state of the substance is a physical property that is very uncertain in deducing what the substance is.
because it is a characteristic property of matter
Physical.
boiling point --------- Boiling point is a specific characteristic of a substance or element; the mechanical strength, the viscosity, the electrical resistivity are more difficult to be used for a sure identification of a substance.
No definitely not.Because a characteristic property should not change.It is used to identify a substance.Mass and Volume are not characteristic properties whereas Density is a characteristic property of the substance .
Characteristic Property
melting point
color,odor,texture,and shape.
True

Density is a Characteristic Property because it is A quality of a substance that never changes and can be used to identify the substances.
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
Just about any property that can be observed or measured can help you reduce the number of options.
