The logic conflict of the second law of thermodynamics
The description of the second law of thermodynamics is that the thermal activity of an independent system always make entropy increase and make it maximum(stable balance)
There is some requirement for the subject of the second law of thermodynamics, which is independent system. While for the following independent system, there are problems when the second law of thermodynamics is applied. There are two cups A and B of water on the table. There are many floating charges. The outside doesn’t have any effect on them. So overall they can be viewed as independent system. From the second law of thermodynamics, the system should have a stable balanced state. From part like A, It is affected by B’s charges. So it cannot be viewed as independent system. And it is a big question whether it has a stable state or not. The same applies to B. Same subject and different conclusions show that the theory has disadvantage when applied to such subject.
Whether the system has stable state or not, should be determined by physical equations which should includes heat and electricity.
1 Poisson Equation
2 Boltzman Equation Ï=A*exp(qu/kT)
It is hard to solve the equations. They are not linear. From instinct, the probability of that they can be solved is very small.
It shows the second law of thermodynamics is only practical when there is not long-distance system. For example, there two internal combustion engines working in a classroom. The interaction between them is universal gravitation, which is too small and the effect of it can be negleted.
But the universal gravitation between celestial bodies cannot be negleted. It will also ruin the independence inside a system. Any galaxy is affected by other galaxies. So the second law of thermodynamics is not suitable anymore. Theory of heat death of cosmos is practically meaningless.
The above is obstacle of language and logic. The following two parts of discussion is on problems of calculation.
******************************************
The equation H=G+ST is not correct under the condition of remote-interaction system.
The second law of thermodynamics shows that there is some constraint condition in the process of heat energy’s transform into function, which is that heat energy can be divide into two parts: the ordered energy ( can be transformed into function) and disordered energy( can’t be transformed into function).
This is H=G+ST
Suppose a system whose different parts have different temperature, which is the common analysis by physics who often divide the system into many little parts and each parts’ temperature is think as the same, then the above formulation can be rewritten as the following.
h=g+s*T
Using g and s is very common in the advanced theory of thermodynamics. Even if the temperature is the same everywhere, using the equation h=g+s*T, is more correct, because it maintain the continuity of physical law.
Now let us image an object with electricity and each parts are interacted with others by the remote electromagnetic, it is natural that electromagnetic energy doesn’t belongs to any local part. In this system, we can’t divide it into many parts, but the temperature has the local part’s characteristic. So the formulation h=g+s*T can’t be applied. This has essentially broken the world of ordered energy and disordered energy.
