Is called Thermodynamics the branch of physics that studies heat and the principles of its distribution throughout the volume of a substance or a particular environment. This discipline is based on some General universal principles and uses experimental data of many other Sciences. Thermodynamic equilibrium is a cornerstone of this sphere of scientific knowledge.

Thermodynamic equilibrium

One of the most important and perhaps the most specific property of living organisms is their unique ability to transform energy and storing it in different forms. Thermodynamic equilibrium – it is a state of the system, where its parameters and characteristics can change over time without exposure to any external factors.

That is theoretically isolated physical system consisting of one or more physical objects could be in a state of balance. If you break the thermodynamic equilibrium, any system will tend to return to its stable state alone. This is one of the fundamental principles of physics on which it built too much in our lives and in nature.

concepts of thermodynamics

It is easiest to imagine the thermodynamic equilibrium on the example of this natural human attribute, like a thermos of hot tea, which represents the isolated system. Of course, the temperature at any point of the substance (in this case, tea) will be the same. But if you put it in a thermos of ice cube, the thermodynamic equilibrium is instantly broken, because there will be a difference of temperatures in different parts of the liquid.

Thus the heat transfer will occur from a region of higher temperature towards colder areas, until the entire volume is established uniformity of the thermal regime. When this happens, stability will be restored. Each thermodynamic system, regardless of its scale and the number of objects of which it is composed.

equilibrium Condition

The Basic equilibrium condition, which is the same temperature increased in all points of the system, especially important for living organisms. All biological features to sustain human life requires a regular supply of energy. All biological processes require a stable heat transfer and uniform distribution.

For Example, plants that accumulate solar energy and transform it in chemical bonds of organic substances through photosynthesis. In animals, everything happens exactly the opposite – organic substances derived from food are converted into energy. All these processes (the representatives of both plant and wildlife) occur in strict accordance with the principles of a thermodynamic system.

Basic concepts of thermodynamics are universal and eternal for living biological systems and inanimate nature. Principles of thermodynamics says that any collection of related objects can be called thermodynamic system. The only difference is the scale and number of objects. Examples of such systems can serve as the cells of our body, heart, or other internal organs. The entire body also in some sense a thermodynamic system. Even such giant entities as the biosphere, the oceans also belong to this category. And they are subject to the same laws of thermodynamic equilibrium.
