STP-তে একটি আদর্শ গ্যাসকে প্রথমে তার প্রাথমিক আয়তনের এক-তৃতীয়াংশে সংকুচিত করা হয়, এবং তারপর প্রসারিত হতে দেওয়া হয় যতক্ষণ না তার চাপ প্রাথমিক চাপের অর্ধেক হয়। উভয় প্রক্রিয়ায় গ্যাসের তাপমাত্রা স্থির থাকে। যদি গ্যাসের প্রাথমিক অভ্যন্তরীণ শক্তি । হয়ে থাকে তাহলে এর চূড়ান্ত অভ্যন্তরীণ শক্তি কত?
