Why are all samples of a given substance have the same intensive properties?

The properties of a pure substance do not vary from sample to sample because there is no reason for them to. Why would they? Water is water, and if you take any sample of water from any stream, lake or ocean and remove all the "stuff" in it to leave only the water, all the samples will behave the same way physically and chemically. The chemical properties of a substance (and the physical ones, too) are set by what the substance is. And these properties define the way the substance behaves in the universe as a whole. There is no reason for any water found on, say Mars, to behave any differently than any water here on Earth - or anywhere else in the universe.

Do all samples of a substance have different physical properties?
Yes, two substances can have the same physical property. For example, both water and ethanol are clear. For this reason, multiple properties must be examined when determining the identity of a substance.
Do the physical properties substance change At any given location?
True!
What is meant by a characteristic property of a substance?
Since characteristic properties for a given substance never change, they can be used to identify unknown matter.
What is the difference between chemical and physical property?
A chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected for its chemical properties to be investigated.A physical property is any measurable property the value of which describes a physical system's state at any given moment in time. For that reason the changes in the physical properties of a system can be used to describe its transformations (or evolutions between its momentary states).
What are 4 examples of chemical properties?
A chemical property is whichever of a substance's properties that develop into obvious for the duration of a chemical rejoinder that is any superiority that can be recognized merely by varying a material's substance individuality. Minimally language, substance properties cannot be established immediately by screening or poignant the essence substance's interior construction must be influenced for its chemical properties to be explored. On the other hand catalytic possessions would also be substance chattels. Chemical properties can be differenceed with corporeal properties which can be distinguished devoid of altering material's configuration. However for loads of properties surrounded by the capacity of corporal chemistry and supplementary disciplines at frontier among chemistry and physics the peculiarity may be a subject of researcher's outlook. Material properties both corporal and chemical can be viewed as supervenient. Several layers of superveniency are potential. Substance properties can be utilized for construction substance arrangements. They can also be constructive to classify an unidentified material to take apart it from other substances. Materials knowledge will in general think about the substance properties of a material to channel its submissions.Some chemical properties are Heat of combustion, Enthalpy of formation, Toxicity, Chemical stability in a given environment, Flammability (The ability to burn), Preferred oxidation state(s), Coordination number. Chemical Properties are domestic properties which are not exhibited peripherally.
How are characteristic properties of given substance different from its other properties and chemical properties?
A substance's characteristic properties are the most recognizable properties of that substance. Chemical properties are exhibited as one substance is chemically transformed into another (e.g., iron rusting).
Do all samples of a substance have different physical properties?
Yes, two substances can have the same physical property. For example, both water and ethanol are clear. For this reason, multiple properties must be examined when determining the identity of a substance.
At any given location the physical properties of a substance do not change?

How does freezing point get calculated if boiling point of an aqueous solution is given?
F.p.'s and B.p.'s are independent (intensive) properties, you can NOT calculate them.
Is clour of light given off by a neon lamp intensive or extensive property?
It is a intensive property.
What is an example of a pure substance and why?
Table salt [sodium chloride], sugar [sucrose], water [H2O], Oxygen[O2] A pure substance is a substance that has a fixed composition and differs from a mixture in that every sample of a given of a pure substance has exactly the same characteristic properties and compositions.
Is carbon dioxide raw material?
No, it is a pure substance. A "pure substance" does not mean an element. Rather, it means that the given substance has definite physical and chemical properties. "Pure substances" can be either "Elements" or "Compounds" because all substances belonging to these categories have definite physical and chemical properties.A mixture does not have definite physical and chemical properties, and combine in varying proportions.
What are the properties of matters?
PROPERTIES OF MATTER 1. A Substance may be identified by certain Qualities, or Traits. A QUALITY OR TRAIT THAT IDENTIFIES A SUBSTANCE IS CALLED A PROPERTY. 2. The property of a substance stays the SAME even if the Volume changes. 3. COLOR, MASS, SMALL, DENSITY, AND COMPOSITION ARE ALL EXAMPLES OF PROPERTIES THAT CAN HELP SCIENTIST IDENTIFY SUBSTANCES. 4. A PROPERTY THAT ALWAYS STAYS THE SAME IS CALLED A CHARACTERISTIC PROPERTY BECAUSE IT IS A CHARACTERISTIC OF A PARTICULAR KIND OF MATTER. 5. EVERY SUBSTANCE HAS TWO KINDS OF PROPERTIES - PHYSICAL PROPERTIES AND CHEMICAL PROPERTIES. 6. A PHSICAL PROPERTY is a property of matter that can be OBSERVED or MEASURED WITHOUT CHANGING the composition of the substance. 7. Physical properties are often used to identify substances. 8. SOME PHYSICAL PROPERTIES OF MATTER: A. BIOLING POINT - The temperature at which a substance changes from a liquid to a gas. B. CONDENSATION POINT - The temperature at which a substance changes from a gas to liquid; same temperature as boiling point. C. DENSITY - The mass of a specific volume of substance. D. FREEZING POINT - The temperature at which a substance changes from a liquid to a solid; same temperature as melting point. E. MELTING POINT - The temperature at which a substance changes from a solid to a liquid. F. RESISTANCE - The opposition of a substance has to the flow of electric current. G. SOLUBILITY - The degree to which a substance will dissolve in a given amount of another substance, such as water.
