Dab tsi txiav txim siab qhov ziab kom qhuav?

Kev txiav txim siab ntawm qhov ziab kom qhuav yog tsim raws li hom kuab tshuaj, vim ntau cov kuab tshuaj muaj cov ntsiab lus sib txawv. Piv txwv li, zinc chloride muaj qhov melting point ntawm 283 degree thiab boiling point ntawm 732 degree, hos ammonium chloride pib sublime ntawm 350 degree. Yog li, thaum zinc chloride siv los ua cov kuab tshuaj, qhov ziab ziab tuaj yeem siab dua thaum siv ammonium chloride. Feem ntau, qhov ziab kom qhuav rau zinc chloride yog teem rau ntawm 200-250 degree, thaum rau ammonium chloride, nws tsuas yog nyob ib ncig ntawm 120 degree. Kev hais lus nruj me ntsis, qhov txwv siab tshaj ntawm qhov ziab kom qhuav yog txiav txim siab los ntawm qhov chaw melting ntawm cov kuab tshuaj tivthaiv, thiab qhov txwv qis yog txiav txim siab los ntawm qhov kub ntawm cov dej siv lead ua hauv cov kuab tshuaj tiv thaiv tuaj yeem tshem tawm tag nrho.
