Question

Entropy (S) is a measure of:
  1. A
    Disorder or randomness of a system
    Correct
  2. B
    Heat content
  3. C
    Free energy
  4. D
    Internal energy

Correct answer

Disorder or randomness of a system

Explanation

Entropy (S) quantifies the disorder or randomness of a system. Boltzmann's equation: S = k ln W, where W = number of microstates. Spontaneous processes generally increase entropy of the universe.
