Dej ua tau ua tsis yog muaj qhov qis melting point piv rau lwm cov sib txuas covalent. Feem ntau ntawm qis molar mass covalent compounds yog gaseous ntawm chav tsev kub thaum dej yog kua. Covalent daim ntawv cog lus muaj zog txaus, tab sis lawv tsuas yog txwv rau ib tus neeg molecules tsis yog tag nrho cov khoom sib xyaw.
Kuj tseem paub yog, cov dej puas muaj qhov kub siab melting point?
0 ° C
Tsis tas li ntawd, nws txhais li cas kom muaj qhov qis melting? " Melting "yog lo lus siv nyob rau hauv physics los qhia thaum ib tug khoom hloov mus rau hauv ib tug kua. Yog li - Mercury muaj qhov melting point tsawg , ntau qis tshaj Hlau. Cov ntaub ntawv hais txog " siab melting point "los yog" qis melting point " feem ntau yog piv rau chav tsev kub, vim txhua yam hauv lub ntiaj teb yog txheeb ze rau lwm yam.
Tsis tas li ntawd, cov kua dej puas muaj cov ntsiab lus melting tsawg?
Txij li qhov teeb meem tshwj xeeb muaj qhov melting tsawg , yog li ntawd nws yog ua kua . Hom teeb meem no yog hu ua khov. Txij li thaum attraction muaj zog heev ntawm cov hais nyob rau hauv cov khoom nws yuav tsum tau ib tug ntau ntawm lub zog los kov yeej no attraction, thiab tus nqi ntawm lub zog no tsis muaj nyob rau hauv chav tsev. kub.
Cov dej puas cuam tshuam qhov melting point?
Dej freezes ntawm tib qhov kub thiab hloov mus rau hauv dej khov. Nws yog ib qho nyuaj rau cua sov cov khoom kom kub siab tshaj lawv melting cov ntsiab lus , yog li nrhiav tau melting point yog ib txoj hauv kev zoo los txheeb xyuas cov khoom.

Cov nanotubes puas muaj cov ntsiab lus melting siab?
Qhov teeb tsa tau tso cai tswj hwm tus kheej nanoparticles thiab cua sov tus neeg CNTs los ntawm kev siv tam sim no rau lawv. CNTs tau pom los tiv thaiv qhov kub thiab txias, mus txog qhov melting point ntawm 60-nm-inch W particles (~ 3400 K)
Cov hlau hloov pauv puas muaj cov ntsiab lus melting tsawg?
Cov ntsiab lus melting-cov ntsiab lus ntawm cov hlau hloov pauv yog siab vim 3d electrons muaj rau cov hlau sib txuas. Qhov ntom ntawm cov hlau hloov pauv yog siab rau tib yam li cov ntsiab lus kub kub. Cov hlau hloov pauv yog tag nrho cov hlau ntom ntom nrog cov ntsiab lus siab melting thiab kub kub
Dab tsi alkali hlau muaj qhov melting tsawg tshaj plaws?
Hauv cov hlau alkali, Francium muaj qhov qis tshaj plaws ntawm 27 degrees Celsius
Vim li cas dej thiaj li muaj qhov melting siab?
Yog vim li cas rau qhov kub melting thiab boiling kub yog cov hydrogen bonding ntawm cov dej molecules uas ua rau lawv los ua ke thiab tiv thaiv raug rub tawm, uas yog tshwm sim thaum dej khov yaj thiab dej boils los ua ib tug roj
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
