Qhov sib txawv tseem ceeb ntawm qhov kub ntawm qhov kub thiab txias yog qhov kub ntawm qhov kub ntawm 1 atm yog qhov kub ntawm qhov kub thiab txias ntawm 1 bar yog qhov ntsuas kub ntawm 1 atm.
Lub ntsiab lus kub ntawm cov khoom yog qhov kub ntawm qhov vapor siab ntawm cov kua ua sib npaug rau lub siab nyob ib puag ncig cov kua. Yog li, ntawm qhov ntsuas kub no, lub xeev ntawm cov khoom hloov pauv ntawm cov kua rau vapor. Txawm li cas los xij, qhov kub ntawm qhov sib txawv nyob ntawm qee yam xws li lub zog ntawm lub zog nruab nrab ntawm cov molecules ntawm cov kua, branching ntawm cov molecule, cov pa roj carbon atoms hauv hydrocarbons, thiab lwm yam. Tsis tas li ntawd, muaj ob hom boiling point raws li ib txwm thiab txheem boiling point. Ob qho no sib txawv ntawm ib leeg nyob ntawm qhov siab ntawm huab cua uas peb ntsuas qhov ntsuas kub.
Dab tsi yog Boiling Point?
Ib txwm boiling point yog qhov kub kub ntawm cov kua ntawm 1 atm siab. Ntxiv mus, atmospheric boiling point thiab atmospheric siab boiling point yog ob lub ntsiab lus rau lo lus no.
Daim duab 01: Dej Boiling
Ntawm qhov kub ntawm qhov kub no, lub vapor siab ntawm cov kua sib npaug 1 atm (uas yog lub ntsiab lus atmospheric siab ntawm hiav txwv theem. Thaum lub sijhawm no, lub vapor siab ntawm cov kua overcomes lub atmospheric siab thiab vim li ntawd, npuas. ntawm kua vapor forms.
Tus Qauv Boiling Point yog dab tsi?
Tus qauv kub kub yog qhov kub kub ntawm cov kua ntawm 1 bar. Tsis tas li ntawd, nws yog qhov ntsuas kub uas peb xav tias yog IUPAC txhais taw tes rau qhov kub thiab txias (txij li xyoo 1982). Piv txwv li, tus qauv boiling point ntawm dej yog 99.61 ° C ntawm 1 bar.
Qhov txawv ntawm qhov Boiling Point thiab Standard Boiling Point yog dab tsi?
Cov ntsiab lus kub ib txwm thiab cov qauv kub sib txawv ntawm ib leeg raws li qhov siab ntawm qhov peb ntsuas qhov kub kub. Yog li, qhov sib txawv tseem ceeb ntawm qhov kub ntawm qhov kub thiab txias yog qhov kub ntawm qhov kub ntawm 1 atm yog qhov kub ntawm qhov kub ntawm 1 bar, qhov kub ntawm qhov kub ntawm 1 bar yog qhov kub ntawm qhov kub ntawm 1 atm. Piv txwv li, qhov kub ntawm cov dej ib txwm yog 99.97 ° C ntawm 1 atm thaum tus qauv boiling point ntawm 1 bar yog 99.61 ° C.
Summary – Ib txwm Boiling Point vs Standard Boiling Point
Raws li lub siab uas peb ntsuas qhov kub ntawm cov kua, qhov kub kub ntawm tib cov kua yuav txawv. Qhov sib txawv tseem ceeb ntawm qhov kub ntawm qhov kub thiab txias yog qhov kub ntawm qhov kub ntawm 1 atm yog qhov kub ntawm qhov kub thiab txias ntawm 1 bar yog qhov ntsuas kub ntawm qhov kub thiab txias.
