Entropy measures the disorder of a closed system. It indicates the capability of self-transformation of this system. Entropy is maximum when the system reaches equilibrium and is incapable of further modification. The temperature becomes uniform, the system takes the simplest configuration and the states of the particles the less ordered and the most probable. Without external energy or influence, the system cannot be reversed. The milk blend in the coffee, the coffee becomes colder – that is, it reaches room temperature The second principle of Thermodynamics stipulates that the entropy ( or disorder) of a closed can only increase. That means its disorder increases to a maximum, which is the total lack of order. Information, which can be measured by its complexity, is sometimes referred as negative entropy of negentropy.
