non-porus materials such as painted or bare metal may have residual contamination.
it is possible to estimate how long specific chemicals will linger on non-porous materials.

The property that can be used to identify what all objects are made of is their chemical composition. This involves determining the elements and compounds present in an object by analyzing its atomic and molecular structure.
The amount of chemical energy an object has is influenced by the types and quantities of chemical bonds present in the object's molecules. The specific compounds and elements in the object determine the potential energy stored in those bonds. The temperatures and pressure conditions also affect the amount of chemical energy present by influencing the stability and reactivity of the molecules.
.... by measurement with an device designed for one particular property: balance for mass, thermometer for temperature, ruler for length, spectrophotometer for color, photometer for light, etc.
The length of an object changing is a physical change, as it does not involve a change in the substance's chemical composition.

To identify the material in an object without altering it, you should use physical properties. Physical properties, such as color, density, melting point, and conductivity, can be observed and measured without changing the substance's chemical structure. In contrast, chemical properties involve reactions that would alter the material, making them unsuitable for non-destructive identification.

In Physics it is a Machine that has the capability to Perform WORK on an Object.
Yes, it is possible. To identify an object using its density you need only a few things: an accurate scale to find the mass of the object; a graduated cylinder large enough to accommodate whatever object you have; the object itself; and a liquid. Any liquid can be used for this, however, if the object floats then the calculation becomes slightly more complicated. I use water. First weigh the object, then immerse it in the liquid. Note how much water is displaced. Divide the mass of the object by the volume of the liquid and you'll find the density. Then compare that density to the list of known densities to identify the object. Pretty simple! physical and chemical properties can be uesed to identify substance. I used: http://www.ehow.com/how-does_5187289_density-used-identify-substances.html Ans: Not sure you can actually identify the substance from its density alone: you would have to know its state too. For example, water in gaseous form would be an entirely different density to water in solid form wouldn't it? So no, you cannot identify a substance from its density, without other information. The best way to identify a substance is often through spectroscopy, in which the radiation either absorbed or given off from a chemical can determine which substances are present. This is what happens for the sun.
They identify the Greek gods on an object by symbols or pictures on the object that relate to the god, i.e. a trident for Poseidon, or a lightning bolt for Zeus.
