Gibbs entropy

Gibbs entropy is a concept from statistical mechanics that helps us understand the disorder or randomness in a system. It measures how many ways a given state can be arranged without changing its overall energy. The more arrangements possible, the higher the entropy, indicating greater disorder. This concept ties into the idea that systems tend to evolve from ordered states to disordered ones. In essence, Gibbs entropy quantifies uncertainty in a system's microscopic states, reflecting how energy is distributed among the particles, which affects processes like thermodynamics and the behavior of gases.
