   Gigrometr yordamida xavoning nisbiy namligini aniqlang. Buning uchun tirqish orqali quticha (1) ga 2-2.5 sm³ efir qo‘ying vash u tirqishga termometr tushiring (2-b rasm). Rezina koptokcha yordamida naycha 2 orqali havo beriladi. Bu holda efirning bug‘lanishi tezlashib, quticha devori soviy boshlaydi. Natijada shudring hosil bo‘ladi.
   
5. 
   SHudring hosil bo‘lgan temperatura t₂ ni termometr bilan belgilab oling.
