Those two properties are mass and temperature. But then, current theoretical physics has been incapable of defining what is temperature? There are two recognized indefinable properties that remain so, meaning they are unexplained, by today's theoretical physics. My explanation is, of course, not orthodox.

In the free expansion example, after things have settled down into an equilibrium state, the fact that the temperature is cut by half, I did refer to an expansion of double, means that it takes twice as long for the molecular kinetic energy of the ideal gas to be transferred from molecule to molecule from the beginning of the hypothetical circle to its end. It is the time it takes, from beginning to end, for molecular kinetic energy to be transferred from ideal gas molecule to ideal gas molecule as if those molecules were lined up in a circle. However, thermodynamic entropy remains what it is.

4.1 How to understand ShannonвЂ™s information entropy Entropy measures the degree of our lack of information about a system. We have changed their notation to avoid confusion. Unfortunately, in the information theory, the symbol for entropy is Hand the constant k B is absent. The free expansion example is not representative of the Carnot engine derivation that Clausius used. This expression is called Shannon Entropy or Information Entropy. Temperature, in its modified form, is the rate at which that molecular kinetic energy is transferred from molecule to molecule. Now to answer your question, thermodynamic entropy is the time it takes for molecular kinetic energy to be transferred from molecule to molecule.

Thus thermodynamic entropy is the time it takes for heat to be absorbed by the molecules of ideal gas, at the constant temperature of the heat source, in a Carnot engine. Thermodynamic entropy is the ratio of heat, which is energy in transit, to temperature. The measurement of this modified temperature is a measurement of the rate at which energy is transferred between molecules. All that is needed is to determine the proper proportionality constant and temperature becomes that which should have originally been recognized as temperature. The effect of this was that the measurement called a measurement of temperature is not a measurement of what is really temperature. This can't be readily shown because the units of degrees Kelvin were arbitrarily set. Therefore, the entropy change is 33.7j/K. Yes, thermodynamic entropy is a measure of time. Example: Calculate the entropy of a reaction if the amount of heat transfer is 9200 joules and the temperature change is 274K. Clausius' thermodynamic entropy is the time it takes for molecular kinetic energy to be transferred from one molecule to another. Even though this is unofficial, because officially no one knows what Clausius' thermodynamic entropy is, i will tell you what it is. I know what Clausius' thermodynamic entropy is, but, as pointed out, his derivation does not apply to free expansion. The question you ask actually is not one that is described by Clausius' mathematics. It is currently officially unknown what is thermodynamic entropy.
