Cov boiling point yog qhov kub ntawm cov khoom uas hloov los ntawm cov kua mus rau ib tug roj (boils) thaum lub yaj point yog qhov kub thiab txias uas cov khoom hloov ntawm cov khoom mus rau cov kua ( yaj ). Nco ntsoov tias cov khoom siv yaj point yog tib yam li nws qhov chaw khov.
Ntxiv mus, qhov txawv ntawm qhov kub thiab txias yog dab tsi?
Lub ntsiab qhov sib txawv ntawm qhov boiling point thiab melting point yog tus melting point txhais tau tias yog qhov kub thiab txias ntawm cov khoom thiab cov theem ua kua nyob rau hauv qhov sib npaug, whereas lub kub point yog qhov kub ntawm qhov vapor siab ntawm cov kua yog sib npaug rau sab nraud siab.
Kuj Paub, dab tsi yog qhov boiling point thiab melting point ntawm dej? 100 ° C
Kuj tseem yuav paub, lub siab muaj feem cuam tshuam li cas rau melting point?
Melting nws yuav ua rau kom qhov ntim ntawm cov khoom ntawd nce ntxiv vim cov kua siv ntau qhov chaw dua li cov khib nyiab. Yog koj nce lub siab , nws yuav nyuaj rau qhov kev hloov pauv ntawd tshwm sim. Nws nyuaj dua los hloov mus rau hauv lub xeev uas xav tau ntau dua yog tias koj nyob hauv qab siab ! Yog li, koj xav tau ntau zog, li no kub, rau yaj.
Dab tsi yog qhov kub taub hau hauv physics?
Cov kub point ntawm ib yam khoom yog qhov kub Thaum lub vapor siab ntawm cov kua sib npaug ntawm lub siab nyob ib puag ncig cov kua thiab cov kua hloov mus rau hauv vapor. Cov kua dej ntawm lub siab muaj qhov siab dua kub point tshaj li thaum cov kua nyob rau ntawm atmospheric siab.
