APAKAH MAKSUD EFFUSIOMETER dalam CORSICA?
Undang-undang Graham
Undang-undang Graham, yang dikenali sebagai hukum pengaliran Graham, dirumuskan oleh ahli kimia fizik Scotland, Thomas Graham pada tahun 1848. Graham mendapati secara eksperimen bahawa kadar pengaliran gas adalah berkadar berbanding dengan punca kuasa jisim zarah-zarahnya. Formula ini boleh ditulis sebagai: di mana: Rate1 adalah kadar pengaliran gas pertama. Kadar2 adalah kadar pengaliran untuk gas kedua. M1 adalah jisim molar gas 1 M2 adalah jisim molar gas 2. p1 adalah tekanan gas 1. p2 adalah tekanan gas 2. Undang-undang Graham menyatakan bahawa kadar pengaliran gas adalah berkadar berbanding dengan dataran akar berat molekulnya. Oleh itu, jika berat molekul satu gas adalah empat kali ganda daripada yang lain, ia akan meresap melalui palam berliang atau melarikan diri melalui pinhole kecil dalam sebuah kapal pada separuh kadar yang lain. Penjelasan teoretikal yang lengkap mengenai undang-undang Graham telah disediakan beberapa tahun kemudian oleh teori kinetik gas. Undang-undang Graham memberikan asas untuk memisahkan isotop dengan penyebaran - satu kaedah yang memainkan peranan penting dalam pembangunan bom atom.
Definisi effusiometer dalam kamus Corsica
