Qhov sib txawv tseem ceeb ntawm qhov sib txawv thiab qhov tsis sib haum xeeb yog qhov sib xyaw ua ke ntawm melting point yog hais txog qhov kub thiab txias ntawm qhov melting ntawm cov khoom rau hauv nws daim ntawv ua kua tshwm sim nyob rau hauv ib txoj kev uas cov muaj pes tsawg leeg tsis hloov, whereas incongruent melting point hais txog mus rau qhov kub ntawm qhov melting ntawm ib yam khoom tshwm sim nyob rau hauv ib txoj kev uas muaj pes tsawg leeg hloov.
Lub ntsiab lus melting ntawm ib yam khoom yog tsim thaum nws melts sharply ntawm qhov kub thiab txias mus rau hauv cov kua ntawm tib yam li cov khoom uas cov kua tsim. Lub ntsiab lus melting tsis sib haum ntawm ib yam khoom yog tsim thaum nws yaj mus rau cov kua uas muaj qhov sib txawv ntawm cov khoom sib txawv. Cov ntsiab lus melting tsis sib haum thiab tsis sib haum feem ntau tshwm sim hauv ob lub cev.
Cia li npau taws yog dab tsi?
Lub ntsiab lus melting ntawm ib yam khoom tshwm sim thaum cov khoom melts sharply ntawm qhov kub tsis tu ncua mus rau hauv cov kua ntawm tib yam li cov khoom uas cov kua tsim. Hom melting no tshwm sim thaum ib yam khoom uas melts uniformly. Ib qho piv txwv ntawm hom melting no yog magnesium-zinc system (Mg(Zn)2).
Dab tsi yog qhov tsis sib haum xeeb Melting Point?
Lub ntsiab lus melting tsis sib haum ntawm cov khoom yog tsim thaum cov khoom yaj mus rau cov kua uas muaj cov khoom sib txawv ntawm cov khoom sib txawv. Hom melting no tshwm sim thaum cov khoom tsis yaj tsis sib xws.
Ib qho piv txwv ntawm hom melting no yog sodium chloride-dej system uas muaj ob lub ntsiab lus tsim cov khoom sib txawv thaum melting (xws li cov khoom siv sodium chloride, dej khov, kua sib tov, sodium chloride hauv kev koom tes nrog ob lub dej molecules. – NaCl.2H2O).
Dab tsi yog qhov sib txawv ntawm qhov sib txawv thiab qhov tsis sib haum xeeb?
Lub ntsiab lus melting ntawm ib yam khoom tshwm sim thaum nws melts sharply ntawm qhov kub thiab txias mus rau hauv cov kua ntawm tib yam li cov khoom uas cov kua tsim. Txawm li cas los xij, qhov tsis sib haum xeeb melting point ntawm ib yam khoom tshwm sim thaum nws yaj mus rau cov kua uas muaj qhov sib txawv ntawm cov khoom sib txawv. Qhov sib txawv tseem ceeb ntawm qhov sib txuam thiab qhov tsis sib haum xeeb yog qhov sib txuam melting point yog hais txog qhov kub thiab txias ntawm qhov melting ntawm cov khoom rau hauv nws cov kua daim ntawv tshwm sim nyob rau hauv ib txoj kev uas cov muaj pes tsawg leeg tsis hloov, whereas incongruent melting point yog hais txog qhov kub ntawm qhov uas. melting ntawm ib yam khoom tshwm sim nyob rau hauv ib txoj kev uas muaj pes tsawg leeg hloov.
Ntxiv mus, cov txheej txheem magnesium-zinc (Mg (Zn) 2) yog ib qho piv txwv ntawm kev sib txuam melting whereas sodium chloride-dej system yog ib qho piv txwv ntawm incongruent melting.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm qhov sib xyaw thiab qhov tsis sib haum xeeb ntawm cov ntsiab lus sib xyaw ua ke rau ib sab ntawm kev sib piv.
Summary – Congruent vs Inongruent Melting Point
Cov ntsiab lus tsis sib haum thiab tsis sib haum xeeb feem ntau tshwm sim hauv ob lub ntsiab lus. Nov yog ob lo lus tawm tsam. Qhov sib txawv tseem ceeb ntawm qhov sib txuam thiab qhov tsis sib haum xeeb yog qhov sib xyaw melting point yog hais txog qhov kub ntawm qhov uas cov khoom melting rau hauv nws daim ntawv ua kua tshwm sim nyob rau hauv ib txoj kev uas cov muaj pes tsawg leeg tsis hloov, whereas incongruent melting point yog hais txog qhov kub thiab txias. uas lub melting ntawm ib yam khoom tshwm sim nyob rau hauv ib txoj kev uas muaj pes tsawg leeg hloov.
