what are the characteristics properties of a pure substance?

['Pure substances are mostly homogeneous in nature containing only one type of atoms or molecules.', 'These substances mainly have a constant or uniform composition throughout.', 'The substances have fixed boiling and melting points.']

Chemical properties are characteristic properties of elements shown during chemical change. Chemical properties are properties of an element or compound that are seen during any chemical reactions.

Extensive properties vary with the amount of the substance and include mass, weight, and volume. Intensive properties, in contrast, do not depend on the amount of the substance; they include color, melting point, boiling point, electrical conductivity, and physical state at a given temperature.

Physical Properties. Physical properties include form (particulate or bulk); porosity (micro- or macroporosity, non- or interconnecting porosity); surface area; and crystallinity (reflecting crystal size, crystal perfection, and grain size as affected by sintering conditions).

The properties of matter include any traits that can be measured, such as an object's density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.

Classifying how a substance looks and how it smells does not require changing its composition. Thus, nitrogen's lack of color and odor are physical properties. Some other examples of physical properties are viscosity, density, melting point, volume, and ductility.
914153
These properties are classified as physical properties and chemical properties. Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.

State of matter: solid, liquid, gas, plasma etc. Physical properties like density, melting point etc. Mechanical properties like hardness, strength, brittleness or ductility etc. Optical properties like transparent, opaque, translucent etc.

Extensive properties, such as mass and volume depend on the amount of substance present and are not useful in the identification of a substance. In this experiment, we will use three properties to identify a liquid substance: solubility, density and boiling point..

Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

The fundamental properties that we use to measure matter in are; Inertia, Mass, Weight, Volume, Density and Specific Gravity. The periodic table is a visual method of interpreting the chemical properties of elements which effect the measurements below.

Summary. Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.

Determination of chemical properties results in the change of the identity of the substance. Some properties, such as solubility, melting point, boiling point, and density are independent of the amount of substance being examined. These properties are known as intensive properties and are used to identify a substance.

A pure substance has a constant composition and cannot be separated into simpler substances by physical means. There are two types of pure substances: elements and compounds. Elements: are pure substances made up of only l type of atom. Atoms of the same element are identical in properties.
