Did you know that we can measure the state of disorder in your room?
Have you ever heard being in a small place: Do not talk so much because it's hotter?
The answer to that is Entropia Energy!

There is a type of Energy called Entropy which is something elusive in physics itself and is defined as:
Thermodynamic magnitude that indicates the degree of molecular disorder of a system. and tends to move from ordered to disorganized states and successively to the chaos of the system.
Entropy is applied to physical, chemical and even business systems. What if! also in your room.
A good interpretation, the level of advance of a system with respect to its equilibrium point or the number of possible combinations of states for the same system.
For example, Suppose your room is in complete order (low Entropy) and for some reason it is disordered (High level of Entropy) if the Entroy levels are very high ie the room is very messy it will cost more work return to its initial state, which is logical.
Ludwig Boltzmann and others developed the Statistical Mechanics which is deeply related to Entropy and Thermodynamics, this Mr. establishes the following relationship between Entropy and thermodynamic probability: S=k.Ln(W ) where W and k are the number of possible states for the system and the Boltzmann constant (k=1.3806488(13)×10^-23J/K) respectively.
Continuing with the example of the room, to measure the levels of Entropy we need to know the possible states or configurations that your room can be, for that it is necessary to invoke the gods of the Statistical Mechanics, once echo that we have to calculate S (Entropy) and we would have the level of Entropy.

Another simple Example of Entropy would be if we add a drop of ink to a glass of water and we hope that it dissolves completely, the glass with water by itself maintains a low level of Entropy and when adding ink increases the level of disorder molecular and therefore the Entropia. Something curious is that this process is reversible because once the ink is added it dissolves spontaneously or naturally, we will never see the ink diluted in water concentrate in a drop.
Speaking in thermodynamic terms we can define it as the thermodynamic magnitude that measures the part of the energy not usable to do work and that is expressed as the quotient between the heat given by a body and its absolute temperature. This idea of thermodynamic disorder was captured by a function devised by Rudolf Clausius where I postulate the following: S = δQ / T and ΔS = S2-S1 = δQ / T.
For this type of systems Entropy is not measured in an absolute way but in between.
Example In an internal combustion engine such as automobiles the energy of loss that does not produce work (movement) such as heat and friction are manifested as entropy.

By the way is a Corvette LT1 6.2L engine with 460HP of power.
Thanks for your time and attention.
