Entropy

Subject: Chemistry

Book: General Chemistry

Entropy (S) measures the degree of disorder or randomness in a system. Higher entropy corresponds to greater molecular randomness. Processes like melting or vaporization typically increase entropy. The second law of thermodynamics states that for any spontaneous process, the entropy of the universe increases. Entropy changes help determine whether a process is thermodynamically favorable and guide the direction of natural processes.
