What is Thermodynamics, What Does It Mean?

The part of physics that studies the relationships between thermal and mechanical phenomena. It examines the nature of heat, its motions, and its transformation into other forms of energy. It is based on two laws:

1. Law of conservation of early (equivalence of work with heat) In other words, work completely goes into heat. 2. The second law establishes that heat cannot pass from a relatively cold body to a relatively hot body without any change in any of these bodies.

However, this law is a finite law and does not apply to systems made up of a small number of particles (valid N). Generalizing this law leads to false assumptions about the thermal end of the universe, or thermal death for short. The ignorant thinkers who apply (in other words, generalize) this law to the entire universe will say that the celestial bodies in incandescent state will one day radiate all their heat to the cosmic space, and as a result, the universe will be a heap of frozen objects (because, as we always know, an object at a certain temperature cools down by moving to a colder environment). radiates heat into that new environment), and from this they deduce that the religious myth of the end of the world is true.

This is a completely unscientific assumption; because it contradicts the law of conservation of energy, which states that motion is indestructible not only quantitatively but also qualitatively. Motion is transformed from form to form infinitely and infinitely (new astronomy has proven that the motion of matter never ceases). To argue that motion can only exist in one form (i.e., an infinitely frozen body) is to fundamentally deny the law of conservation of energy. Moreover, there cannot be motionless matter (that is, the universe cannot be an infinitely frozen conglomeration of cosmic bodies that do not transform into any other form); that is, matter cannot exist in a state in which motion does not pass from one state to another. This unscientific assumption, which was organized according to certain interests, was also refuted by Friedrich Engels (See Engels Dialectique de la Nature, Editions Sociales, Paris 1955, pp. 44-6). The thermal death of the universe means that it is completely unscientific to assume that all forms of motion will take the form of heat, never to be transformed into any other form.
