A pure substance has a definite and constant composition, meaning it is made up of only one type of molecule or element. It has specific physical and chemical properties that help identify and distinguish it from other substances. Pure substances can exist in different phases (solid, liquid, gas) depending on temperature and pressure conditions.
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 etc...

A substance is a general term used to describe matter with uniform properties, while a pure substance refers to a substance with a specific chemical composition and constant properties throughout. In other words, pure substances consist of only one type of atom or molecule, whereas substances can be mixtures of different components.
How can you separate a pure substnace?
A pure substance can be separated by physical methods such as distillation, filtration, or chromatography depending on the properties of the substance. These methods exploit differences in physical properties such as boiling point, solubility, or size to isolate individual components of the substance.
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.
What are the properties of an element?
pure substance,and chemical substance,
Compare and contrast chemical and physical properties?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
What best describes the different between a mixture and a pure substance?
A mixture has different properties throughout; a pure substance has the same properties throughout.
What arr some of the physical properties of a pure substance?
Physical properties of a pure substance include color, melting point, boiling point, density, solubility, and conductivity. These properties can be used to identify and characterize the substance.
What is a characteristic of pure substance?
A characteristic of a pure substance is that it has a fixed chemical composition, meaning it is made up of only one type of particle or element. This results in consistent physical and chemical properties throughout the substance.
