The value of entropy of solar system is

Options

  1. Aincreasing
  2. Bdecreasing
  3. Cconstant
  4. Dzero

Correct answer

A. increasing

Step-by-step solution

This is the second law of thermodynamics. All spontaneous processes (or naturally occuring processes) are thermodynamically irreversible and accompanied by a net increase of entropy, i.e., for all the spontaneous processes, the total entropy change (sum of the entropy changes of the system and the surroundings) is positive. Thus, "the entropy of the universe is continuously increasing.
