Equilibrium is that condition of matter that allows stability with the forces with which it interacts in the space where it is. This is a generic term that is applied in various fields and situations of everyday life. To create a "Balanced" notion of the term, a series of applications and examples related to the subject should be enunciated. Balance is the capacity that objects have to remain in perfect harmony with related forces and objects, creating and at the same time canceling the interaction so as not to generate a change in their position or state.
What is balance
Table of Contents
This terminology comes from the Latin "aequilibrium", which is composed of "aequus" whose meaning refers to equality; and “pound”, a word that refers to the balance. The term can be defined as the state of a body or object to which all the moments and forces that act on it are added or increased and which, in turn, are counteracted. It can be said that something or someone is in perfect balance when, even without having enough base to support themselves, they are standing and do not fall. We could speak of balance examples, among them, a person who stays statically in the same place.
This type of stability can be recognized when there is harmony and concordance between different things or simply between the parts that make up a whole. Measure, composure, equanimity and good sense are part of balance and can also be related to the mental health of one or more subjects. The conditions of equilibrium can vary, as well as the use of the term in different sciences, as well as to refer to a set or group of activities endowed with prudence to be able to carry a situation or action that is quite complicated, difficult or delicate. The breakeven point can be reached in different ways and can vary according to the context.
The sense of balance
Also known as physical balance, it is one that allows both animals and humans the ability to walk without losing harmony in their steps and falling. The inner ear has a series of organs that send signals to the neuronal system to carry out the movements of both the head and the body, hence balance is managed. There are even several species of animals that tend to have better stability than humans, including cats, as they can walk over fine fences and remain stable thanks to their inner ear and their tail, which allows them to balance in everything. moment.
The animals respond and evaluate the ectopy of equilibrium in which the body is stable against acceleration, gravitation and other forces that have an impact on both position and movement. The marine lungs (jellyfish) are listed as one of the most important examples of balance, as they have the incredible ability to shrink and erect themselves in order to make movements with their head. It is imperative to note that the first organs that refer to physical stability came and evolved from reptiles, amphibians and fish, which began with a very low percentage of hearing, some even lacked it.
When stability is disrupted, it ranges from nausea and dizziness to disorientation of the physical body. It was possible to confirm that balance is greatly affected by meniere's disease, which causes inner ear involvement and its etiology is totally unknown to date. It was also confirmed that stability is momentarily affected by movements of great vigor or that are extremely fast, for example, going too many turns in a rotating chair or amusement game.
Astronauts, for example, lose their balance when they are in orbit, this happens because they are just in a free fall and in constant mode, that generates the so-called space sickness. The sense of balance is also classified into a series of aspects that will be explained below.
Functioning
It is the vestibular system, which is made up of the saccule and the utricle, organs that have the shape of a chamber and that are full of endolymph. The utricle is located in the horizontal area, while the saccule is in the vertical area, in addition, the macules (hair cells) are responsible for covering the walls. In these areas there is a highly gelatinous material that has particles of otoconia, otolith and calcium and when there is some type of movement, the inertia of the otoconia mass causes the cuties to move.
Balance development
This development has different phases and evolves in parallel according to psychomotor development. The first phase has to do with static equilibrium, which has a development oriented at 6 years. The second phase refers to the dynamic balance, which begins to develop just at 9 years of age. This can decline in the time of 35 to 40 years, since this stability does not belong to an innate function, on the contrary, the sensitive phase of balance can improve the central nervous system, but that happens between 5 years and 12 years.
Static equilibrium
Its bases lie in a solely stationary phase, in it there is a relative position between the elements or tools that make up a given system and that does not have a transition over time, but this does not mean that they cannot move, on the contrary, they can be mobile, but do not change position between one component and another.
Balance in motion
Also known as mechanical equilibrium, it deals with a steady state that executes various conditions, each as important as the other. The first is that the system is in harmony or mechanical stability when there is a sum of moments and forces in the particles of the system, then it obtains a base at zero, this could also be called a balance of forces. The second condition is that the system remains in mechanical stability when its position in the configurational space is at a gradient point, that is, of energy-power, which has its base at zero.
Biological equilibrium
This is nothing more than the theory that mentions or establishes that all ecological systems can be in complete stability, this is called homeostasis, which means that there is a small change in the particular parameters of the ecosystems, an example of this is the size of a specific population, which is corrected through negative feedback and, consequently, creates a parameter to establish a new equilibrium point. The ecological balance can be used in different completely dependent procedures, among them, that of the prey / predator system or those links between herbivorous animals and their food.
Food chain
When speaking of the food chain, reference is made to all the food relationships that are previously linearly established between those organisms belonging to the different trophic levels. This chain is classified into two abundant slopes, the first is the grazing network, which has a beginning in algae, plankton and green plants, each one in the realization of photosynthesis. Its components go from plants to herbivorous species and from these to carnivorous ones. The second is the debris network, which begins with organic debris and has networks made up of totally independent food chains.
The materials of this network go from plants to animal substances, then to bacteria and later to fungi, which are in charge of decomposing, they pass to the food of the detritus, which are called detritivores and finally, to the predators.
Human intervention
There are many organizations with a conservationist objective that tend to claim that human activities do not have compatibility with stable ecosystems, however, there are also many balanced examples that explain and cover very well the habitats that come from human activities and that have lasted in the history, among them, the tropical forests that are located in Latin America and that their existence is based on the care of the human generation, as well as the abundance of animals for grazing in the plains of the Serengeti, located in Africa, which is It is believed to be of human origin and that it was established after the creation of habitat in the savannah.
Political Balance
It is an international political state by means of which each power tries to remain stable with respect to the relations it has with other powers or nations, which are affected to prevent or avoid the exercise of exclusive power by them in particular. When there is no stability in any of these nations, then it is in a predominant situation, of hegemony or domination.
Division of powers
It is nothing more than a purely political principle in different governments of the world, which is applied so that the executive, legislative and judicial powers of the nation are exercised by different government organs, which must be autonomous and totally independent. Bearing this in mind, it should be clarified that when speaking of the division of powers, representative democracy in the nation is clear, a fundamental characteristic of democracy.
Balance in Chemistry
In chemistry, we speak of a balanced reaction when there is no progress even though the transformation reaction has developed in two totally opposite directions and that, in addition, equal numbers of molecules have been formed in without having changes in the compounds.
Thermodynamic equilibrium
A system is in equilibrium only when the state variables known as temperature, pressure, density, volume and mass have exactly the same value in each of its points, an example of them is that, when ice cubes are added to a tea, the ice dissolves and the temperature becomes uniform and due to heat transfer, the well-known thermal equilibrium occurs.
Equilibrium constant
It is the value of the reaction constant found in chemical equilibrium, in addition to being a state in which it approaches a dynamic chemical system and that, after a certain time has elapsed, its composition does not have a tendency that can measure yourself for one more change. For the reaction conditions to occur, the constant must be kept independent of the analytical concentrations that have been initially made in the reagent, in addition, the product species are by mixture.
This means that, according to the composition given at the beginning of the system, the constant values of equilibria can be used to determine the composition of that system. It is important to mention that each of these reaction parameters, including temperature, ionic strength and solvent, can have a lot to do with the value of the constant.
Balance in solutions
They are all the relationships of the chemical equilibrium existing between the dissolved and solid states of the compounds in the saturation stage or phase. The consistency of the solutions has to do with the use of constants and chemical fundamentals, which serve to fully predict the solubility of substances under different conditions, since solubility can become quite sensitive to conditions, but constants do not have the same sensitivity impact. In addition, the substance to be dissolved becomes an organic solid, it could be said that like sugar, although it can also be an ionic solid, like salt.
The difference between them is that ionic solids can dissociate into their constituent ions when there is water involved and they dissolve, since water is a solvent of interest even though the basic principles of both are applicable to any type of solvent.
