This has lots of answers; some of them are:
malleability
chemical properties
electrical properties
color
texture
I suspect there are more because the size of something rarely changes the intrinsic properties of that something.

Do minerals have definite chemical and physical properties?
Yes, it is true; but because minerals are frequently not very pure substances differences in properties exist; also many varieties of a mineral are possible.
What is the homogeneous material with with a variable composition?
No. A pure substances has a definite and constant composition.
What properties of substances can you observe and how do these properties determine the usefulness or hazards of a substance?
You can observe physical, chemical, and characteristic properties of a substance and can be used to determine the usefulness of a substance by, giving us information about the substance usually using our 5 senses which are physical properties. Or being able to describe the substances ability to undergo changes to its composition to produce one or more new substances, chemical property. Or even just being able to identify whether or not the substance is pure or not can help us determine if the substance is hazardous or not. two other properties I did not mention were the qualitative and the quantitative properties.
What are physical combinations of different pure substances that can be separated into their original components by physical means?
mixtures
What is the difference between pure and impure substances?
a pure substance is one which only contains one type of atom/molecule and an impure substance is one the has numerous types of atoms/molecules, but the impurites generally dont amount to over 50% of the substance's mass.
What are facts about pure substances?
cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
Pure substance definition?
A pure substance:cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
How are pure substances and mixtures different?
Both mixtures and pure substances have measurable and observable chemical properties and physical properties. A liquid mixture vaporizes over a temperature range; whereas, a pure substance boils at a fixed temperature.
You can use your senses to observe of a substance?
A substance must have the properties of physical properties in order to be observed and measured.
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 differences between pure substances and mixture?
Mixtures can be separated by physical means, whereas pure substances cannot. Also, mixtures are composed of multiple substances, while pure substances are, as the name implies, composed of only one substance.
What is the definition of pure substances?
A pure substance is a substance that consists solely of the same atoms/molecules.So a volume of water that contains only H2O is a pure substance. A block of iron that contains only Fe atoms is pure substance. A pure substance can be composed of atoms or molecules as I said before BUT they have to be exactly the same.A substance that has constant chemical composition and characteristics
What are 2 pure substances?
A pure substance is a homogeneous chemical substance which means its composition is constant and its properties are consistent too. Some examples of this kind of substances are water, baking soda and sucrose.
When two pure substances are combined so that each of the pure substance retains its own properties the result is a?
When two substances combine and retain their own properties, a mixture results.
When two pure substances are combined so that each of the pure substances retain its own properties the result is called?
This is called a mixture.
How can knowing the physical properties of a substance be useful?
The physical properties of a pure substance can be used to identify it. A pure substance is an element or a compound, not a mixture.
Do minerals have definite chemical and physical properties?
Yes, it is true; but because minerals are frequently not very pure substances differences in properties exist; also many varieties of a mineral are possible.
