Lub ntsiab lus ntawm cov kua dej sib txawv raws li qhov kev thov siab; qhov kub ntawm qhov kub thiab txias yog qhov sib npaug ntawm qhov ntsuas dej hiav txwv ntawm huab cua siab (760 mm [29.92 ntiv tes] ntawm mercury). Ntawm hiav txwv theem, dej boils ntawm 100 ° C (212 ° F)
Dab tsi yog qhov kub ntawm chemistry?
Boiling point yog qhov kub ntawm qhov vapor siab ntawm cov tshuaj sib npaug ntawm atmospheric siab Txhawm rau muab, nws ntsuas qhov kub ntawm cov tshuaj boils. Zoo ib yam li cov ntsiab lus melting, qhov kub siab dua qhia tau tias muaj zog ntawm cov molecular ntau dua thiab yog li ntawd tsawg dua vapor siab.
Koj pom qhov kub hnyiab hauv chemistry li cas?
Boiling Point Formula - Boiling Point Elevation Formula & Solved Piv txwv

Dab tsi yog qhov kev txhais lus tshawb fawb ntawm qhov kub?
Lub ntsiab lus kub ntawm cov khoom ntshiab yog qhov kub ntawm cov khoom hloov ntawm cov kua mus rau theem gaseous. Nyob rau ntawm no, lub vapor siab ntawm cov kua yog sib npaug zos rau lub siab thov ntawm cov kua.
Hnub 9 qhov kub hnyiab yog dab tsi?
Hint: Qhov kub ntawm qhov kev hloov pauv ntawm cov kua ntawm cov cua sov yuav tshwm sim ntawm tus qauv atmospheric siab yog hu ua lub boiling point ntawm cov kua thiab qhov tshwm sim hu ua boiling. Ua kom tiav cov kauj ruam los ntawm kev daws teeb meem: … Cov dej ntshiab ntawm tus qauv siab (1atm) boils ntawm 100∘C
