The entropy increase law

The law of entropy states that the total entropy of an isolated system always increases during spontaneous processes.

Disorder Degree: Entropy is a measure of the level of disorder or chaos in a system, which tends to move towards a higher state of disorder.

Thermal Equilibrium: The system reaches maximum entropy when it attains thermal equilibrium, indicating a uniform distribution of energy.

Thermal Efficiency: According to the law of entropy, the efficiency of any thermal engine is limited and cannot convert all thermal energy into work.

Chemical Reactions: The spontaneity of reactions can be predicted by changes in entropy; reactions that increase entropy are more likely to occur spontaneously.

Information Theory: Entropy quantifies uncertainty in information; an increase in entropy indicates an increase in information content.

Cosmic Evolution: The law of entropy helps explain the evolution of the universe from the Big Bang to its eventual state of heat death.
