The term "thermodynamics" states that this theory deals with phenomena in which changes occur in the examined objects, which can be measured with a "thermometer". We assume that the thermometer indicates changes to certain energy states of the objects under investigation.
The basis of "quantum thermodynamics" is the assumption that those kinds of energy, which have an effect on the temperature of the objects, cannot occur in any, but only in "quantized" energy portions.
The model presented here provides an illustrative description of this energy storage, which at the same time accurately converts the mathematical results of the quantum theory without the need for an extensive mathematics for the model itself. The model provides analogies for the thermodynamically relevant phenomena as temperature, thermal energy, entropy and thermal radiation.
