Cov melting point rau gallium (uas yog sawv cev rau ntawm Lub Sijhawm Table li Ga ) yog kuj qis , ntawm 85.6 ° F (29.8 ° C). Txawm li cas los xij, lub kub point rau lub caij no yog siab heev, ntawm 4044 ° F (2229 ° C). Qhov zoo no ua rau gallium zoo tagnrho rau kev kaw kub uas yuav rhuav tshem tus pas ntsuas kub.

Yog li ntawd, vim li cas lub melting point ntawm gallium thiaj li tsawg?

Gallium muaj cov qauv txawv txawv. Txhua atom muaj ib tus neeg nyob ze ze ntawm qhov deb ntawm 2.43 Å. Cov qauv zoo tshaj plaws no nyiam mus rau qhov sib cais diatomic molecules ntau dua li cov qauv hlau. Cov tsawg melting point yog vim cov qauv siv lead ua txawv txawv, tab sis cov qauv tsis muaj nyob hauv cov kua.

Cov hlau twg muaj cov ntsiab lus melting qis tshaj? Alloys nrog melting cov ntsiab lus Hauv qab 450 degrees Fahrenheit yog hu ua qis - yaj los yog fusible alloys. Feem ntau siv fusible alloys muaj feem pua ntawm bismuth, ua ke nrog cov hlau lead, tin, cadmium, indium thiab lwm yam. hlau.

Xav txog qhov no, dab tsi yog qhov melting point ntawm gallium?

29.76°C dej

Dab tsi yog qhov qis melting point?

" Melting "yog lo lus siv nyob rau hauv physics los qhia thaum ib qho khoom hloov mus rau hauv cov kua, Mercury yog ib qho khoom ntawm heev. qhov kub thiab txias , mas " yaj " ntawm li 10 degrees Fahrenheit. Yog li - Mercury muaj a qis melting point , ntau qis tshaj Hlau.
