از ویکی‌پدیا، دانشنامهٔ آزاد

در فیزیک،نیروی آنتروپی یا نیروی درگاشتی در یک سیستم، از گرایش ترمودینامیک کل سیستم به افزایش درگاشت حاصل می‌شود، تا از یک نیرو میکروسکوپیک خاص.[۱]

برای نمونه، انرژی درونی گاز ایده‌آل تنها به دمای آن بسته است و نه به حجم محفظه آن؛ بنابراین این اثر انرژی نیست که باعث افزایش حجم محفظه می‌شود و این نشانگر این است که فشار گاز ایده‌آل منشأ درگاشتی دارد.[۲]

تعریف ریاضی

نیروی آنتروپی مرتبط با یک macrostate partition اینچنین تعریف می‌شود:[۳][۴]

که نشانگر دماست و درگاشت مرتبط با macrostate و نشانگر macrostate فعلی است.
