  2. 2. The Second Law and Entropy: An Orderly Way of Thinking About Disorder The second law of thermodynamics has been described and expressed in many different ways, including the following. 1. Systems tend to proceed from ordered (low entropy or low to disordered (high entropy or high probability) states. 2. The entropy of the system plus surroundings is unchanged by reversible processes; the entropy of the system plus surroundings increases for irreversible processes. 3. All naturally occurring processes proceed toward equilibrium, that is, to a state of minimum potential energy. probability) states
