Physical and chemical properties

Explanation:

There are different types of properties

Physical properties

The physical properties of matter are those characteristics specific to the substance, to be observed or measures do not produce new chemical species, for example:

Smell, color, taste, crystalline shape, temperature melting temperature, boiling temperature, density, viscosity, surface tension, vapor pressure, solubility, hardness, brightness, malleability, ductility, conductivity, etc.

Chemical properties

The chemical properties of matter are those which, when observed or measured, produce new chemical species, by

example: reactivity to oxygen, water or acid.

And these are classified as follows.

Properties that do not depend on the amount of substance considered are called intensive properties, such as melting temperature or density. The so-called extensive properties are those that depend on the amount of material substance, such as volume or mass.

Intensive properties are also called specific because they are characteristics that make it possible to differentiate one substance from another. Also, extensive properties are known as general properties because they are present in all kinds of substance and do not allow them to be differentiated from each other.

On the other hand, chemical properties are those whose measurement implies a change in composition, usually irreversible. Flammability or that a substance is easily oxidized are chemical properties.
