Please note that resistivity also depends on temperature.In the most general case, the answer is definitely NO; all superconductors have the same resistivity, namely zero.
Other than superconductors, take a look at a table with some typical resistivity values. It would seem quite obvious that for a given temperature:
* Two different substances will, in general, have different resistivities.
* In practice, in some cases the difference in resistivity might be too small to reliably measure.
* It should be possible to find two substances that have the same resistivity at a very specific temperature - since the temperature-dependence will vary from one material to another.
* Likewise, it should be possible to design a mix of two substances, which exactly matches that of another, given, substance.

Is a cork made up of rubber?
No, a cork is not made up of rubber. Cork is a natural material derived from the bark of the cork oak tree (Quercus suber). It is composed primarily of a substance called suberin, which gives it its unique properties, such as being lightweight, buoyant, and resistant to moisture. Rubber, on the other hand, is typically derived from the sap of rubber trees (Hevea brasiliensis) and has different chemical properties.

What are the unique specifications of a Coldfusion server?
A Coldfusion server needs unique specifications as it is a unique code. It is used in HTML codes and as such will need the programs and other specifications to run it properly.
How sodium chloride is a substance that has similar properties as sodium and chlorine or is it an entirely different substance with its own unique properties?
Sodium chloride is it an entirely different substance with its own unique properties.
Is density unique to each substance?
Yes, density is unique to each substance. It is a physical property that is defined as the mass of a substance per unit volume. Different substances have different densities based on their molecular structure and composition.
How do scientifics tests help determine to properties of substance?
Characteristic properties are unique for every different substance.
What are the different molecule colors present in the substance?
The substance contains various molecules that each have their own unique color.
Why do different substances have unique odors?
Different substances have unique odors because of their specific chemical composition. Each substance releases molecules that interact with our olfactory receptors in different ways, creating distinct smells that our brain interprets as unique odors.
How is density of a substance like a human fingerprint?
The density of a substance is a unique physical property that remains constant, just like a human fingerprint is unique to each individual. Density is a measure of how tightly packed the molecules in a substance are, and this characteristic can help identify the substance. Just as fingerprints are used for identification purposes, density can be used to distinguish different substances based on their unique values.
What C contains different elements Joined toghether?
A compound is a substance composed of two or more different elements chemically joined together. This joining of elements creates a new substance with unique properties.
Is a compound a single substance?
No, a compound is a substance formed by the chemical combination of two or more elements in fixed proportions. It has a unique chemical structure and properties different from its constituent elements.
What is the temperature at which a given substance will change from a solid into a liquid?
The temperature at which a substance changes from a solid to a liquid is called its melting point. It is a specific temperature unique to each substance and is determined by the intermolecular forces within the substance. When the substance reaches its melting point, the solid will begin to transition into a liquid state.
When a new substance is formed with different propities than tan the original substance it is called what?
When a new substance is formed with different properties than the original substance, it is called a chemical reaction. Chemical reactions involve the breaking and forming of chemical bonds between atoms to create new substances with unique properties.
What is the general name for a pure substance containing different atoms chemically joined together?
A general name for a pure substance containing different atoms chemically joined together is a compound. Compounds are formed when atoms of different elements bond together through chemical reactions to create a new substance with unique properties.
How do you tell how many elements are in a substance?
To determine the number of elements in a substance, you can analyze its chemical composition. Each unique atom present in the substance represents an element. Scientists use techniques like spectroscopy and chemical analysis to identify and count the different elements in a given substance.
