Kaas oo leh heerka ugu sarreeya ee caddaynta qaraxa

Kala soocida aan qarxin: Heerka IIC waa kan ugu sarreeya, oo ka kooban codsiyada IIB iyo IIA; IIB waxay dhaaftay IIA marka la eego qiimeynta.

Heerkulka dusha sare ee ugu badan: Tani waxay tilmaamaysaa heerkulka ugu sarreeya ee qalabka korantada ay ku gaari karaan xaaladaha ugu xun ee hawlgalka, lagana yaabo in uu shido jawiga qarxa ee ku xeeran. Heerkulka ugu sarreeya ee dusha sare waa inuu ka hooseeyaa heerkulka guban kara.

Tusaale ahaan: Deegaannada lagu isticmaalo dareemayaasha aan qarxin, haddii heerkulka shidda ee qarxa gaasasku waa 100 ° C, markaa heerkulka dusha sare ee ugu sarreeya qayb kasta oo ka mid ah dareemaha waa inuu ka hooseeyaa 100 ° C.
