Dub Marble : Marble yog lub pob zeb metamorphic tsim ntawm recrystallized carbonate minerals, feem ntau calcite los yog dolomite. Marble tej zaum yuav foliated. Geologists siv lo lus marble ” xa mus rau metamorphosed limestone; Txawm li cas los xij, stonemasons siv lub ntsiab lus dav dav kom suav nrog cov limestone tsis muaj kev cuam tshuam.
Ib yam li ib tug yuav nug, dab tsi yog marble dub?
Ashford Dub Marble yog lub npe muab rau cov limestone tsaus, quarried los ntawm mines ze Ashford-in-the-Dej, hauv Derbyshire, England. Thaum txiav, tig thiab polished, nws ci dub nto yog zoo nkauj heev. Ashford Dub Marble yog ib lub pob zeb zoo-grained sedimentary, thiab tsis yog qhov tseeb marble nyob rau hauv lub geological kev xav.
Ib yam li ntawd, marble pom nyob qhov twg hauv ntiaj teb? Marble yog pom nyob rau hauv ntau qhov chaw nyob ib ncig ntawm lub ntiaj teb , suav nrog Is Nrias teb, Tim Nkij teb chaws, Spain, Qaib ntxhw, Ltalis, thiab Tebchaws Meskas. Marble tuam txhab uas muag mus rau qhov chaw no mus nrhiav marble raws li cov pob zeb loj hauv nws lub xeev ntuj. Ces, lub marble yog txiav mus rau hauv slabs los yog me me pieces yuav siv tau nyob rau hauv kev tsim kho los yog nyob rau hauv kos duab.
Tsis tas li ntawd, dab tsi yog hom kim tshaj plaws ntawm marble?
Statuario Marble Statuario tej zaum yog qhov zoo tshaj plaws marble ntawm lawv tag nrho. Muab piv rau Calcutta thiab Carrara , nws muaj cov xim veining txawv ntawm kub mus rau grey. Statuario ntog nyob rau hauv nruab nrab ntawm cov nqi ntau.
Dab tsi yog cov yam ntxwv ntawm marble?
Lub cev muaj zog thiab kev siv ntawm Marble
- Xim: Marble feem ntau yog lub teeb xim pob zeb.
- Acid Reaction: Ua los ntawm calcium carbonate, marble yuav hnov mob hauv kev sib cuag nrog ntau cov kua qaub, neutralizing cov kua qaub.
- Hardness: Ua los ntawm calcite, marble muaj qhov hardness ntawm peb ntawm Mohs hardness nplai.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Qhov tshwm sim ntawm xaiv liab lossis xiav marble yog dab tsi?
Qhov tshwm sim ntawm kos duab liab marble = 2/5. Qhov tshwm sim ntawm kev kos duab xiav marble yog tam sim no = 1/4. Qhov tshwm sim ntawm kos duab liab marble = 2/5
Dab tsi yog qhov ceev ntawm marble?
Marble, khoom hnyav 2.711 gram ib cubic centimeter lossis 2 711 kilogram ib cubic meter, piv txwv li qhov ceev ntawm marble, khoom yog sib npaug rau 2 711 kg / m³; ntawm 25.2 ° C (77.36 ° F lossis 298.35K) ntawm tus qauv atmospheric siab
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
