القانون الأول للثرمودايناميك ويعني ان الحرارة والطاقة الميكانيكية
تتحول بالتبادل وهو مانص عليه قانون جول فقانون جول هو القانون الأول للثرمودايناميك اي الطاقة الكهربائية تتحول إلى شغل بتغير حركة الجزيئات الداخلية.وهو مابينا ان تحويل الطاقة الكهربائية إلى شغل من أسهل عمليات التحويل فهي تتحول تلقائيا.ومنه اشتق قانون حفظ الطاقة الذي يلاحظ فيه ان الطاقة الحرارية تساوي الشغل مضافا إليه الطاقة الجزيئية الناتجة من حركة الجزيئات
