A thermodynamic process occurs in which the entropy of a system changes by -6 J/K. According to the second law of thermodynamics, what can you conclude about the entropy change of the environment? It must be +6 J/K or more. It must be between 6 J/K and 0. O it must be equal to 6 J/K. It must be +6 J/K or less. O It must be 0
