Qhov sib txawv tseem ceeb ntawm molten thiab kua yog cov khoom molten yog cov kua uas yog tsim los ntawm melting ib yam khoom uas nyob rau hauv cov khoom nyob rau hauv lub chav tsev kub qhov twg cov kua tshuaj twb twb muaj nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub.
Molten thiab kua yog ob lub xeev ntawm cov teeb meem ntawm qhov ntsuas kub. Txawm hais tias ob lub xeev no muaj tib lub zog ntawm cov kua ib txwm, (xws li muaj peev xwm ntws) muaj qhov sib txawv ntawm lawv txoj kev tsim. Cov khoom molten tsis yog kua; lawv yog tsim los ntawm melting ib yam khoom.
Ntawm yog dab tsi?
Molten substances is liquid state matter tsim los ntawm melting ntawm ib yam khoom. Qhov no txhais tau hais tias thaum ib yam khoom nkag mus rau hauv cov kua hauv lub xeev ntawm cov khoom hauv lub xeev vim muaj kev cuam tshuam sab nraud xws li qhov kub thiab txias, peb hu cov kua hauv lub xeev cov khoom molten. Piv txwv li, molten ntsev yog ntsev uas tau yaj los ntawm kev ua kom kub kom tau cov kua ntsev ntsev. Yog li ntawd, cov txheej txheem no yog ib theem hloov ntawm ib yam khoom. Qhov kev hloov pauv no tshwm sim ntawm qhov chaw melting ntawm cov khoom siv.

Thaum qhov kub thiab txias, cov ntawv cog lus hauv cov khoom tawg, thiab kev txiav txim ntawm ions thiab molecules zoo li tau txais lub xeev qis dua thaum cov khoom melts los ua kua. Feem ntau, cov khoom hauv lub xeev molten muaj qhov viscosity tsawg thaum qhov kub nce, tshwj tsis yog cov leej faj uas nws cov viscosity nce nrog qhov kub thiab txias.
Ua Kua Dej yog dab tsi?
Cov kua dej yog ze li ntawm cov kua dej uas muaj peev xwm ntws. Cov kua tsis muaj cov duab tshwj xeeb, nws tau txais cov duab ntawm lub thawv uas nws nyob hauv, tab sis cov kua tuav lub ntim tas li, thiab lub ntim yog ywj siab ntawm lub siab. Yog li ntawd, qhov no yog ib theem ntawm plaub theem loj ntawm teeb meem. E.g. khoom, kua, roj, thiab plasma.

Ib lub kua muaj cov khoom me me (vibrating hais) ntawm cov teeb meem xws li atoms. Cov khoom no tau tuav ua ke los ntawm cov ntawv cog lus intermolecular. Feem ntau cov kua tiv thaiv compression, tab sis qee cov kua tuaj yeem compressed. Distinctively, ib tug kua muaj cov cuab yeej ntawm nto nro. Cov kua dej ntau tshaj plaws hauv ntiaj teb yog dej.
Qhov txawv ntawm Molten thiab kua yog dab tsi?
Molten thiab kua yog ob lub xeev ntawm cov teeb meem ntawm qhov ntsuas kub. Txawm hais tias ob lub xeev no muaj tib lub zog ntawm cov kua dej ib txwm, (xws li muaj peev xwm ntws) lawv txawv ntawm txoj kev tsim. Qhov sib txawv tseem ceeb ntawm molten thiab kua yog tias cov khoom molten yog cov kua uas yog tsim los ntawm melting ib yam khoom uas nyob rau hauv lub solid-state ntawm chav tsev kub. Lub caij no, cov kua twb twb muaj lawm nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub.
Tsis tas li ntawd, cov khoom molten yog ua los ntawm cov khoom uas nyob hauv cov khoom siv thaum cov kua ua los ntawm ions thiab molecules tuav ua ke los ntawm cov ntawv cog lus sib txuas.
Hauv qab infographic qhia txog qhov sib txawv ntawm molten thiab kua.
Summary – Molten vs Liquid
Molten thiab kua yog ob lub xeev ntawm cov teeb meem ntawm qhov ntsuas kub. Txawm hais tias ob lub xeev no muaj cov khoom zoo ib yam li cov kua ua kua, (xws li muaj peev xwm ntws) lawv txawv ntawm txoj kev tsim. Qhov sib txawv tseem ceeb ntawm molten thiab kua yog cov khoom molten yog cov kua uas yog tsim los ntawm melting ib yam khoom uas nyob rau hauv lub solid-state nyob rau hauv chav tsev kub qhov chaw uas cov kua tshuaj twb twb muaj nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub.
