How To Use The Facts About Physical Properties

When we talk about facts about physical properties of matter, we are referring to those qualities that are feasible to be measured, without causing alterations in the structure of the atoms, they differ from the chemical properties in that they do have changes in the atomic structure of matter.

According to the facts about physical properties, which are they?

Among the most important physical properties, we can highlight:

The Density

This property of matter establishes a relationship between the mass and volume of matter, thus determining the amount of a substance for each unit of volume of the same, this property of matter does not depend on the amount of this, so it is called intensive physical property.

The unit for measuring density in the International System of measurements is the kilogram per cubic meter kg/m3, also using sub-multiples such as grams per cubic centimeter g/cm3.

Mass

Within the physical magnitudes of bodies, mass is the property that refers to the amount of matter present in them, the units used to measure mass are weight units, such as the ton, the kilogram, the gram, the milligram, and the microgram.

This physical property should not be confused with the weight, since it varies depending on the force of gravity, so it will be different depending on the place where the body is, while the mass will always be the same regardless of the force of gravity of the place where the body is.

Boiling point

The physical property that makes a body change from liquid to gaseous state is known as boiling point, and is related to the temperature reached by a body at a given time, occurs when the temperature of the vapor pressure of the substance is equal to the atmospheric pressure outside, is a physical property that is measured in degrees Celsius.

Melting point

It is the temperature at which a substance changes from solid to liquid state, i.e. the temperature at which a body melts, this property is considered as a constant physical property, because, it is a process that does not influence the volume of the substance, it is also measured in degrees centigrade.

Temperature

In common words we can say that temperature refers to the amount of heat or cold that a body or substance presents at a given time, is a property that to be measured requires an instrument called thermometer, to measure this physical property are used two scales known as Celsius and Farenheit, and the units used are called degrees, its increase or decrease is determined by the degree of agitation or vibration presented by the particles that form the body or substance.

Electrical resistance 3

Among the facts about physical properties we have that electrical resistance is the opposition that a material, body, or substance presents to the flow of electric current on it, is a property that is decisive in the selection of the optimal materials for the manufacture of conductors and electrical components, resulting copper as the most economical material to produce such materials, others such as silver, gold, and aluminum have lower resistance, but because of the high cost of these, copper is preferred for production.

Volume 4

Among the facts about physical properties of bodies, volume is a fundamental property that determines the applications and uses of substances and bodies, and refers to the amount of space that a body or substance occupies, and for its measurement volume units are used, which are made up of three dimensions, the liter, centiliter, milliliter, and their multiples and sub-multiples.

There are other qualities such as taste, odor, malleability, and solubility, which are of great importance in defining applications for materials.

In the Echemi Company, there are multiple articles that provide great utility knowing the facts about physical properties of these, such as:

Sodium nitrate

Is a product whose physical properties must be perfectly known in order to establish its applications.

Usefulness of physical properties

The importance of knowing the physical properties is fundamental when it comes to establish the applications that will be given to the materials, the fact that they are feasible to be measured provides more possibilities of knowledge of the material, and therefore an advantage to make decisions of the uses to which they are destined.
