There also exists a formulation of the Third Law which approaches the subject by postulating a specific energy behavior: If the composite of two thermodynamic systems constitutes an isolated system, then any energy exchange in any form between those two systems is bounded.
Ada juga rumusan Hukum Ketiga melalui pendekatan subjek dengan mendalilkan perilaku energi tertentu: Jika gabungan dua sistem termodinamika merupakan sistem yang terisolasi, maka pertukaran energi dalam bentuk apapun antara dua sistem tersebut dibatasi.
