Answer:
the entropy of the universe increases
Explanation:
The second law of thermodynamics can be stated in terms of entropy, in this statement of the law; ''a spontaneous process increases the entropy of the universe''.
Given that; ∆Suniverse = ∆Ssystem + ∆Ssurroundings, the definition of a spontaneous process is one in which ∆Suniverse >0.
Hence, a process is spontaneous when the entropy of the universe increases.
