What are the properties of matter?

Any characteristic that can be measured, such as density, color, mass, volume, length, malleability, melting point, hardness, smell, temperature and more of an object, is considered a property of matter. There are six main physical properties. In order to be able to measure or observe them, we do not need to change the composition of the substance. The six physical properties are color, density, volume, mass, boiling point and melting point.

Of those six, four are intensive, while the other two are extensive. The properties of liquefied gases play a prominent place in the science of production and the study of low-temperature environments. The properties of any substance and the points at which it changes phase are represented in what is known as a phase diagram. Depending on the physical properties of a cholsteric liquid crystal, only certain colors can be reflected.

Since the final materials are the same as the starting materials, the properties (such as color, boiling point, etc.) will also be the same. The physicist's interest, rather, is in issues such as the amount of heat in the fire, the properties of sound waves emitted in the dynamite explosion, etc. Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and its susceptibility to corrosion. Intensive properties, on the other hand, 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.

Scientists usually measure intensive properties to determine the identity of a substance, while extensive properties transmit information about the amount of the substance in a sample. It is necessary to observe the properties of the combination to determine if a new substance has formed. On the other hand, chemical properties can only be measured or observed when we change the chemical identity of a substance. In general, we can measure those properties and determine the size, weight, or composition of a matter.

The four most important chemical properties are the heat of combustion, chemical stability, flammability and the preferred oxidation state. Physical properties are those that can be measured or observed without changing the chemical composition of a matter. A liquid crystal is a substance that, at a specific temperature range, shows properties of both a liquid and a solid. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space a sample takes up).
