Thaum cov khoom hloov mus ua kua nws hu ua yaj . Cov melting point rau dej yog 0 ° C (32 ° F). Thaum qhov sib txawv tshwm sim thiab cov kua hloov mus ua ib qho khoom, nws hu ua khov . Boiling thiab Condensation. Thaum cov kua ua kua yog hu ua boiling los yog vaporization.
Xav txog qhov no, dab tsi yog melting point boiling point thiab freezing point?
Cov kub point yog cov kub ntawm uas cov khoom hloov los ntawm cov kua mus rau ib tug roj (boils) thaum lub melting point yog cov kub uas cov khoom hloov los ntawm cov khoom mus rau cov kua ( yaj ). Nco ntsoov tias cov khoom siv melting point yog tib yam li nws qhov chaw khov.
Kuj Paub, 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.
Ib tug kuj yuav nug, dab tsi yog melting thiab khov point?
Qhov chaw khov yog cov kub ntawm qhov uas cov kua ua ib yam khoom ntawm ib txwm atmospheric siab. Xwb, a melting point yog cov kub ntawm qhov uas ib qho khoom ua kua ntawm ib txwm atmospheric siab.
Vim li cas dej yaj thiab khov ntawm 0 degrees?
Melting thiab khov Raws li lub zog hauv cov molecules nce los ntawm qhov kub thiab txias, cov molecules pib txav nrawm dua. Tsis ntev lawv muaj lub zog txaus los rhuav tshem lawv cov qauv nruj thiab pib txav mus los yooj yim dua. Qhov teeb meem dhau los ua kua. Cov yaj taw tes rau dej yog 0 degrees C (32 qib F).

Dab tsi ntawm melting thiab boiling?
Lub boiling point yog qhov kub ntawm cov khoom uas hloov los ntawm cov kua mus rau ib tug roj (boils) thaum lub melting point yog qhov kub thiab txias uas cov khoom hloov los ntawm cov khoom mus rau ib tug kua (melts). Nco ntsoov tias cov khoom siv melting point yog tib yam li nws qhov chaw khov
