Importance of Thermodynamics

Thermodynamics is a discipline which falls within the physical and that addresses the study of the phenomena related to heat. The interest of the thermodynamics focuses especially on considering the way in which the different forms of energy are transformed and the relationship between these processes and the temperature. Indeed, there are evaluations that establish that the development of the discipline went hand in hand with an attempt to achieve a greater efficiency in the use of machines, efficiency that implied that the least amount of energy was lost in the form of heat.

Thermodynamics and its laws

The thermodynamics It has a series of laws that account for the way in which energy behaves. The first of these is the so-called principle of conservation of energy, a principle that establishes that energy cannot be created or destroyed, but only transformed into another form; In this way, heat is nothing more than a form of energy that will derive from others, such as job. As for the second principle of

thermodynamics, it establishes that a process of increasing entropy exists in a closed system, understanding by entropy a process of chaos in which energy becomes unusable. Finally, the third law of thermodynamics states that it is impossible to reach the absolute CEO in a system through a finite number of steps.

In addition to the aforementioned laws, there is a zero principle that establishes that different thermal systems will reach equilibrium with each other if they are in some way in contact. Thus, if a system A is in contact with a system B and this system B is in contact with another system C, eventually all of them will reach equilibrium, that is, they will have the same temperature. This principle leads to the inference that the universe had a beginning and is far from being static, because otherwise it should already have reached equilibrium.

Study of thermodynamics as a discipline

Finally, it should be noted that the thermodynamics as a discipline it developed over several centuries, always having the interest of making better use of energy. This is why it was always linked to different inventions and experiments, always with a strong practical edge. Nowadays, it is enormously descriptive of the phenomena that take place in regard to energy and especially in what refers to processes related to heat.
