All substances have certain properties that define it. We can often measure these properties and determine the size, weight, or composition of a substance. For example, we can determine that wood is mostly brown and thus detect its color attributes. There are several properties that are considered essential, and these properties are often divided into physical and chemical properties.
We also distinguish between the extensive and intensive properties of matter. Physical properties refer to properties that can be measured or observed without changing the chemical composition of a substance. Volume and color, among other things, fall into this category.
On the other hand, chemical properties can only be measured or observed when we change the chemical properties of a substance. Extensive and dense properties are just physical properties, but they are divided into two specific groups. Broad properties, such as volume and mass, depend on the amount of matter we measure, while dense properties, such as color and density, are not.
There are six main physical properties. In order for us 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 these six, four are fortified, while the other two are extensive.
The wide range of physical properties are volume and mass. Their value depends on the amount of substance we measure. The strength properties of a substance are color, density, boiling point, and melting point. These are permanent; They do not change depending on the amount of matter. It makes sense that no matter how much of a particular substance you have, its color doesn't change.
We can also mention other attributes here, but these belong to these six attributes and are considered the most important. Other material properties worth mentioning include refractive index, temperature, and hardness, among others. These are intensive properties and are often described as bulk properties. They do not depend on the size of the system we are measuring, or the amount of material that can be found in that system.
We have already mentioned that chemical properties are properties that we can only measure by changing the chemical structure of the substance being measured. This means that these properties measure how a substance behaves in a chemical reaction. These properties only become apparent during such a reaction. The four most important chemical properties are heat of combustion, chemical stability, flammability, and preferred oxidation state.
The heat of combustion is the property of the energy released by a substance when it is completely burned through the use of oxygen. This property measures the amount of energy released during such reactions. Chemical stability is the property that determines whether a substance will react or not in a particular environment. It is mainly observed by putting the compound in water or leaving it outside to observe its reaction with the air. These reactions are called hydrolysis and oxidation.
The next chemical property is flammability, which measures the ability to burn. Through flammability, we can see whether a substance will burn once it is exposed to fire. Combustion is a chemical reaction, and by placing a substance underneath it, we can determine how flammable it is and how quickly it burns. Finally, the preferred oxidation state determines the level of oxidation of a given compound that requires the least amount of energy. In general, the oxidation state is the degree of oxidation (loss of electrons) of the compound, and the preferred oxidation state is the one that requires the least energy.
