There were derived many forms of the Planck distribution function (PDF) since its discovery by Planck in 1900 and formulae for the positions of Wien´s peaks in those distributions. There were published many attempts searching for the hidden carriers of heat because the existing known heat effects of photons cannot interpret all observed data. In this presented model we work with concept of fission of one Solar photon into two thermons – the missing carriers of heat. Properties of Solar photons and Solar thermons are compared for the surface of the Sun and in the vicinity of the Earth. Solar thermons obey the Stefan-Boltzmann law and their heat action can be experimentally analyzed in the whole volume of the Solar System. One of those effects can explain the microwave background radiation as the reflection of thermons on the surface of the Termination shock. The measure of the quantity of heat S for thermons is constant in agreement with the Carnot´s model. The specific heat of solids was newly interpreted as the joint action of three types of thermons with frequency ν/2, ν, and 2ν. The ratio of these three thermons can be experimentally determined from infrared spectra of those studied solids. This model could bring a new way to better describe the old, predicted concept of “dark heat” as appeared many times in the historical literature. We have summarized the known forms of the PDF and positions of Wien´s peaks in order to search some hidden properties in those mathematical structures. It will be shown that these very well-known formulae to all scholars might still keep some hidden surprising properties.

Experimental and theoretical results about entropy limits for macroscopic and single-particle systems are reviewed. All experiments confirm the minimum system entropy S⩾kln2. We clarify in which cases it is possible to speak about a minimum system entropykln2 and in which cases about a quantum of entropy. Conceptual tensions with the third law of thermodynamics, with the additivity of entropy, with statistical calculations, and with entropy production are resolved. Black hole entropy is surveyed. Claims for smaller system entropy values are shown to contradict the requirement of observability, which, as possibly argued for the first time here, also implies the minimum system entropy kln2. The uncertainty relations involving the Boltzmann constant and the possibility of deriving thermodynamics from the existence of minimum system entropy enable one to speak about a general principle that is valid across nature.

“…One of those earlier models of heat was based on the carrier of heat termed as caloric, e.g. [12]- [31]. There is one old topic in physics -entropy -the term entropy was introduced by Clausius in 1865 [5] and since that time the meaning of the entropy was many times discussed and evaluated, e.g.…”

There were derived many forms of theories of heat during the past three hundred years. At its origins, thermodynamics was the study of heat and engines and therefore, we should be connected to these roots. In this model we present thermons as carriers of heat from hot bodies to cold bodies. The flow of heat is modelled as the transfer of angular momentum of these thermons in the direction from the higher angular momentum to the lower angular momentum of thermons. The mechanical equivalent of heat J is defined as the ratio of the angular momentum of thermons to the temperature of the surrounding. This model newly defines the quantity of heat – entropy S – as the ratio of the angular momentum of thermons to the temperature of the surrounding. This model can open a new window to the microworld where quantum particles transfer their heat content in one direction. However, this direction can be changed via the work done on these quantum particles and to reverse the flow of the angular momentum from lower angular momentum to higher angular momentum of those quantum particles. It will be shown that these very well-known formulae of S to all scholars might still keep some hidden surprising properties.
