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.
What else can I help you with?
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.
Is vapour pressure intensive property?
Yes, vapor pressure is an intensive property because it does not depend on the amount of substance present. It is characteristic of the specific substance at a given temperature and does not change with the quantity of the substance.
Is boiling point intensive property?
Yes, boiling point is an intensive property because it does not depend on the amount of the substance present. It is a characteristic property that remains constant for a pure substance at a given pressure.
Why two samples of the same pure substance react the same way?
Because they are composed of the very same atoms. There is no difference between their composition, and hence there can be no difference in the way they react. Atoms of the same element have no personalities or individuality; they will always behave the same (given all other conditions are also equal).
Do the physical properties substance change At any given location?
No, the physical properties of a substance do not change at a given location unless there is a change in temperature, pressure, or state of matter. These properties include characteristics like density, color, odor, melting point, boiling point, and solubility.

Is vapour pressure intensive property?
Yes, vapor pressure is an intensive property because it does not depend on the amount of substance present. It is characteristic of the specific substance at a given temperature and does not change with the quantity of the substance.
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).
Density is an example of?
Mass, volume, and density are all example of physical properties. Physical properties are any characteristic of a substance that can be observed or measured without changing the material.
Is boiling point intensive property?
Yes, boiling point is an intensive property because it does not depend on the amount of the substance present. It is a characteristic property that remains constant for a pure substance at a given pressure.
What kind of property is temperature?
Temperature is an intensive property, meaning it does not depend on the size or amount of the substance, but rather represents a specific characteristic of the substance at a given moment in time.
At any given location the physical properties of a substance do not change?
no
Do the physical properties of a substance change At any given location?
True
Is clour of light given off by a neon lamp intensive or extensive property?
The color of light given off by a neon lamp is an intensive property because it does not depend on the amount of neon present in the lamp. It is a characteristic specific to neon atoms that remains constant regardless of the quantity of the substance.
Which is an extensive physical property color density length boiling point?
Density is an extensive physical property, as it depends on the amount of substance present in a given volume. Boiling point is also an extensive property as it relates to the quantity of substance being heated. Color and length are intensive properties, as they do not depend on the amount of the substance present.
Why two samples of the same pure substance react the same way?
Because they are composed of the very same atoms. There is no difference between their composition, and hence there can be no difference in the way they react.
