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.
