What will be the change in entropy of the surroundings in a spontaneous process occurring in an isolated system?

When spontaneous process occurs then free energy of a system

What will be the value of the change in internal energy of a process occurring in an isolated system?

Some statements are given with regard to entropy. The incorrect statement(s) are (A) The absolute entropy of substances cannot be determined (B) In standard state entropy of elements is always positive (C ) The entropy of universe always decreases (D) In a spontaneous process, for an isolated system the entropy of the system generally increases

Assertion :- In an isolated system the entropy increases due to spontanous process. Reason :- The processes in an isolated system are adiabatic.
