What is the Meaning & Definition of thermodynamics

Thermodynamics is the discipline dealing with science mother, physics, the study of the relationships between heat and other forms of energy. Inter alia thermodynamics deals with analyzing the effects that the changes of quantities such as: temperature, density, pressure, mass, volume, systems and at a macroscopic level.
The basis on which all the thermodynamics studies looming is the movement of energy and like this it is able to infuse movement.
It is worth noting that it was precisely this issue which promoted the development of this science, since its origin was due to the need to increase the efficiency of early steam engines.
Then, since this kick, thermodynamics, has held to describe how it is that systems respond to changes that occur in their environment, and can be applied to an infinite number of situations, both of the science as engineering, such as: motors, chemical reactions, transport phenomena, phase transitions, black holes, among others. And therefore its results are really appreciated by Chemistry Physics and chemical engineering.
Meanwhile, thermodynamics presents three fundamental laws... the first law is popularly known as the principle of conservation of energy and argues that if a system exchanges heat with another, its own internal energy changes. In this case, the heat will be the required energy that must exchange a system to compensate for differences between the internal energy and work.
On the other hand, the second law, proposes various restrictions on transfers of energy, which could be if one takes into account the first law; the second principle speaks of regulation of direction in which carry out thermodynamic processes, imposing the possibility that these are developed in the opposite direction. This second law is supported in entropy (physical quantity measuring part of the energy that can be used to produce work).
And the third and last act holds that it is impossible to reach a temperature that is equal to absolute zero through a finite number of physical processes.
And the most important processes taking place in thermodynamics are: isothermal (temperature does not change), isobaric (pressure unchanged), Isochoric (volume does not change) and adiabatic (no heat transfer occurs).
