A pure substance is a material which contains atoms of only one kind.
It has fixed physical and chemical properties like boiling point, melting point, valency, density.
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
An extensive property. Examples include mass and volume, which vary based on the quantity of matter present in a substance.
Characteristic properties of a substance do not change when the sample changes. These properties, such as melting point, boiling point, density, and chemical reactivity, are inherent to the substance itself and remain constant regardless of the size or form of the sample.
it has no effect. density of a substance is the same no matter the size or shape of the sample.
Every sample of matter is not a substance because a matter may include multiple substances. A substance contains only one kind of matter.
The characteristic that depends on the amount of matter in a sample is its mass. Mass is a measure of the amount of matter in an object or substance, and it can change depending on how much of the substance is present.

characteristic property :)
One example of a property that remains constant regardless of sample size is density. Density is the mass of a substance per unit volume, and it stays the same no matter how much of the substance is present.
An extensive property. Examples include mass and volume, which vary based on the quantity of matter present in a substance.
A substance is matter that has a uniform and consistent composition, meaning it contains the same types and proportions of atoms or molecules throughout. This results in substances having characteristic properties that do not vary within the sample.

No density if a characteristic of matter. Density can vary with temperature and pressure, but a chunk of something twice the volume of another chunk of the same substance will weigh twice as much because the two chunks have the same density.
Every sample of matter is not a substance because a matter may include multiple substances. A substance contains only one kind of matter.
The chemical composition and intrinsic properties, such as density, melting point, boiling point, and specific heat capacity, will remain the same regardless of the sample size. These properties are characteristic of the substance itself and do not change with the amount of the sample.
Volume and mass are not characteristic properties of matter because they can change based on external conditions, such as temperature and pressure. Characteristic properties are those that remain constant and unique to a specific substance regardless of the amount or sample size, such as density or boiling point.
