Expert Answer:

When changes occur within a closed system its entropy either increases (for irreversible processes ) or remains constant (for reversible processes). It never decreases.
 
In equation form, this statement becomes
ΔS ≥ 0.
 
> sign applies to irreversible process. Equal sign applies to reversible process.
