Entropy: A negative form of Information?

Entropy is the measure of degree of randomness in a system. More the randomness more is the system stable. Any reaction which results in the creation of more number of particles or when matter in the solid state goes to liquid state and from liquid state to gaseous state results in increase of entropy. Entropy is related to the heat energy which is the form of energy all other energies when used tend to change into. Heat causes the increase in the randomness of the motion of the particles in the matter. The entropy thus is connected with chaos. It… Read More »Entropy: A negative form of Information?
