Density is an intrinsic property of each type of material, defined as the total mass divided by the total volume. Obviously, two samples of the material which have the same mass and same volume will have the same density, but that is not that answer to this question. This question is about the thermodynamic state of a material and the answer is temperature and pressure.

The thermodynamic state of a system is a set of properties that are reproducible when the thermodynamic variables have been specified.

Density is one such property. Specifying the temperature, pressure and specifying the quantity and type of material of a system determines density at equilibrium.

The equilibrium condition is critically important in that assertion.

It is a fundamental premise of thermodynamics that the state of a simple system at equilibrium can be completely characterized by specifying two independent property variables, such as temperature and pressure, and the quantities of the chemical constituents.

Any system then with the same thermodynamic state has the same intrinsic properties such as density, heat capacity, thermal conductivity, viscosity, and other characteristics.

If Using density how dowe determine if a substance is pure or not?

If a substance is not pure, the density may, or may not, change, compared to the pure substance.


What is a pure substance classified as?

A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.


What classifies a substance as a pure substance?

A pure substance is a substance that is constant throughout. Such as water, tin or sulfur.


What are two reasons why density is a useful property identifying substances?

Density can tell you how "pure" a substance is. Since each substance has a specific density in its "pure" state, having no other substances in its composition, by measuring it density you can tell how pure the mineral or substance is, 99.9% pure gold.


What are two reasons why density is a useful property for identifying substances?

Density is specific for each substance. Also the measurement is generally simple.


What is the only way the density of a pure substance can change?

By changing the temperature as you can't add anything to a pure substance.


How is water a pure substance?

Pure substances fall into two categories: elements or compounds, both of which have constant compositions. H2O is a compound, and therefore a pure substance because its composition does not vary.


What is the homogeneous material with with a variable composition?

No. A pure substances has a definite and constant composition.


Pure substance definition?

A pure substance:cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition


Compared to a bar of pure gold what is the density of a pure gold ring?

If both objects are pure gold then the density is the same. Weight and mass are not factors in this particular question.


If Archimedes had only been able to find a piece of pure gold with a mass one-half that of the crown how could he have determined whether the crown was pure gold?

Archimedes came across concept of density - that is MASS divided by VOLUME. For each substance this ratio is different but a CONSTANT for that substance. Thus the mass you are dealing with is irrelevant if the crown had the same ratio as the piece of pure gold then the crown was pure god, if it did not then the crown was not gold.


Is The density of a substance is the same for all samples of the substance?

Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
