The word volume has different definitions depending on the scope. One of them is as a physical property of matter: it is the space that a body occupies. The International System of Units establishes the cubic meter as the main unit of volume. There are also the cubic decimeter, the cubic centimeter and the widely used liter (L). The space occupied by matter can be measured quantitatively in any of several arbitrary units or dimensions. Mathematically the mass or dimensionn is defined as a Euclidean proportion, besides it is included as a Riemannian manifold.
What is Volume
Table of Contents
It is a metric proportion of the scalar type, which is defined as the size in three dimensions of an area of space. It is a proportion from the length, since it is found by multiplying the length, the height and the width. From the mathematical point of view, it is defined not only in any Euclidean proportion, but also in another class of metric spaces that, for example, include Riemannian manifolds.
The volume, or the space occupied by a body, can be measured quantitatively in any of many arbitrary units or dimensions.
There are different ways to measure the volume of bodies; To measure the volume of a liquid, a transparent instrument such as a graduated cylinder or measuring cylinder, burette and pipette is used, generally they have a gradual scale of cubic centimeters or mL.
In solid bodies of regular shape, it is measured by its dimensions and is obtained by applying the corresponding mathematical formula. For example; For three-dimensional figures such as the cube or parallelepiped, the volume is the product of its three dimensions (length, width and height).
In addition, the volume of a gas can also be measured by storing it on water or any other liquid, measuring the amount displaced.
The concept of volume is related to that of capacity. Capacity refers to the proportion of something, where another could be contained. The unit of capacity is the liter, which ends up being equivalent to the unit of volume in liquid state, or what is called cubic deciliter.
In chemistry, the molar volume is the volume occupied by one mole of particles of a solid, liquid or gaseous substance, under normal conditions of pressure and temperature.
Volume types
There are four different types:
Dough volume
There is an erroneous belief that mass volume is an accepted term, however, they are two words that, although they do have a relationship, are each studied separately, as described below:
On the one hand, mass is a quality of material systems that quantify the amount of mass they have. Its element in the international system is the Kg (kilogram). In the same way, it is usual to use the gr (gram) and mg (milligrams). A balance is used to calculate the mass. The balance is a tool that allows relating the mass of a material system with the unit of mass.
On the other hand, the meaning of volume indicates that it is a property of the material systems in charge of informing the amount of proportion it occupies. Its element in the international system is the m3 (cubic meters). The liter (L) and the milliliter (ml) are also frequently used.
Sound volume
It is the sound sensation that every human being has of the intensity of a certain sound.
The power of a sound is defined as the measure of energy (acoustic power) that passes through a surface per second, therefore, the higher the power, the greater the volume. However, it should not be confused with loudness, which is the subjective pickup of intensity.
The perception of volume continues on a logarithmic scale, its scale is measured in decibels and where the so-called acoustic power level is determined.
Volume Booster
The sound amplifier is a device that is responsible for increasing the audio signal before it reaches the ears. This has two fundamental functions: it corrects and increases the sound signal. An example of these devices or applications is the volume booster, which allows you to adjust the volume of a terminal in a specific way.
The volume unit converter becomes an indispensable intermediary between the speakers and the sound player. If you connect a CD player directly or a microphone to speakers, for example, very weak sound will be heard. This is where you will need a device that can increase the audio signal.
Another essential function of these sound amplifiers is to suppress distortions so that you can increase volume and continue to hear an imperceptible sound. In addition to that, most sound amplifiers also allow you to control the sound from the device itself.
Mean Corpuscular Volume or MCV
It is an indicator used in blood tests (hermetic cytometry), representing the average of the individual volume of erythrocytes (red blood cells).
The mean corpuscular volume is measured as follows:
- VCM = (HCT / RBC) * 10, where Hct is the hematocrit, in percent.
- RBC (red blood cell count) which is the erythrocyte count, represented in millions of cells per microliter.
According to the value in which this parameter was found, two conceptions emerged; macrocytic and microcytic (macro = large, micro = small, citic = cell). For a woman or a man who has a mean corpuscular volume of 120 it is estimated macrocytic, while an MCV of 98 is estimated macrocytic only in men.
An individual with a very large alteration in the size of his erythrocytes is an indicator that he has anisocytosis (an = lack of, iso = equal, cyto = cell, osis = condition of), that is, they are unequal cells.
This indicator is calculated by automated hematic cytometry devices, which are characterized by measuring and counting the size of blood cells, this is where the Coulter method is most used.
Volume on books
The Romans called a strip of parchment or papyrus that functioned as a support for writing that was later kept in a roll. The lines of the writing, placed in columns, flow in a parallel direction extending in the strip, unrolling it horizontally.
The volume conceptually conforms (since its inception) a physical division. The tome is a thematic constitution within the book. This can comprise several volumes, and it can have several volumes; but the binding separates the volumes, and the segmentation of the book distinguishes the volumes.
Formulas for drawing and calculating volume
There are a variety of formulas to calculate this unit of measurement, which allows calculations and measurements to be made for it, which are:
Formula for the volume of a solid. Some of these formulas are used for common plane figures in 2 or 3 dimensions. The results have one, two or three dimensions; area is calculated in square units, perimeter is calculated in linear units, and volume is calculated in cubic units.
- Cube V = s 3 s represents the length of the side.
- Right rectangular prism V = LWH L symbolizes the length, W the width and H the height.
- Prism or cylinder V = Ah A is the area of the base, h is the height.
- Pyramid or cone V = 1/3 Ah A is the area of the base, h is the height.
- Sphere V = 4/3 r is the radius.
Volume examples
Volume of a solid body
It is given by the size of the element, that is, its width, its height and its length is expressed mathematically. Its units of measurement can be the cubic decimeter, cubic meter or the cubic centimeter. Example: The volume of a suitcase is 70 cm³.
Volume of a liquid body
It is represented by the space that a body can occupy, its unit of measurement is the mL. Example: A large bottle can fill with 1000 mL of water.
Volume of an irregular body
An irregular matter with distorted dimensions can be calculated by the amount of altered. For example: in a container, a certain amount of water is added depending on the liquid that the container can hold, a space is left for when the object is added the water can rise. The total body achieved after putting it in, will be the total of your physical volume
Gas volume
Using instruments such as gas syringes, it is possible to specify the range of a gas sent by a chemical reaction (the amount of gas). Example: Your measurement is used in arterial blood gas.
Acoustic volume
The volume of the sound is calculated according to the range of the sound wave produced. It is a subjective shock of the level achieved by a sound in the ear. Its quantitative metric unit is the decibel (dB). Example: The weakness of a sound or the strength of the sound.
