- Harorat – vaqt”
- Ish bajarish uchun komponentlar turi o‘qituvchi tomonidan beriladi va quyidagicha bo‘lishi mumkin: Naftalin-difenilamin
“Harorat – vaqt” sovush egrilari (V.1– rasm) va jadvaldagi ma’lumotlardan foydalanib, sistemaning suyuqlanish (yoki qotish) diagrammasi (V.2– rasm) chiziladi. Buning uchun ordinatalar o‘qiga kristallanishning boshlanish va tugash haroratlari, absissalar o‘qiga esa aralashmalar tarkibi qo‘yiladi. Ish bajarish uchun komponentlar turi o‘qituvchi tomonidan beriladi va quyidagicha bo‘lishi mumkin: Naftalin-difenilamin Azobenzol-naftalin Benzoy kislotasi-naftalin Naftalin-nitrotoluol Fenol-metilamin Moddaning suyuqlanish haroratiga qarab, suvli hammom o‘rniga moyli yoki glitserinli hammom ishlatiladi. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Nazorat Savollari 1. “Faza”, “omponent”, “komponentlar soni”, “erkinlik darajasi”, “mustaqil parametrlar” tushunchalari. 2.
