A dej molecule tsim thaum ob atoms ntawm hydrogen daim ntawv cog lus covalently nrog ib tug atom ntawm oxygen. Nyob rau hauv covalent bond electrons yog sib koom ntawm atoms. Cov pa oxygen atom nyiam cov electrons ntau dua li cov hydrogen. Qhov no muab dej ib qho asymmetrical faib ntawm tus nqi.
Ib yam li ntawd, tib neeg nug, ua li cas dej molecule?
A dej molecule muaj peb atoms; ib qho oxygen atom thiab ob lub hydrogen atoms, uas yog kev sib txuas ua ke zoo li cov hlau nplaum me me. Cov atoms muaj cov teeb meem uas muaj cov nucleus nyob hauv nruab nrab. Qhov kev nyiam ntawm cov protons thiab electrons yog qhov ua kom lub atom ua ke.
Ib yam li ntawd, dab tsi ua rau hydrogen bonding ntawm dej molecules? Hydrogen - kev sib raug zoo ua kua dej raws li cov hydrogen atoms ib dej molecule yog attracted rau lub oxygen atom ntawm ib tug nyob sib ze dej molecule ; Feem ntau, ib tug proton sib koom los ntawm ob leeg electron khub. Yog li ntawd, cov pa oxygen atom yog ib feem tsis zoo them, thiab cov hydrogen atom yog ib feem zoo them.
Tsis tas li ntawd, hom molecule yog dej dab tsi?
Dej Molecule -- Tshuaj thiab lub cev muaj zog. Dej yog a chemical compound thiab polar molecule, uas yog kua ntawm tus qauv kub thiab siab. Nws muaj tshuaj qauv H2O , txhais tau hais tias ib qho molecule ntawm dej yog tsim los ntawm ob hydrogen atoms thiab ib oxygen atom.
Cov qauv dej yog dab tsi?
H2O

Vim li cas cov nthwv dej transverse tsim los ntawm av qeeg hu ua cov nthwv dej thib ob?
Secondary waves (S-waves) yog shear waves uas yog transverse nyob rau hauv cov xwm. Tom qab muaj xwm txheej av qeeg, S-nthwv dej tuaj txog ntawm cov chaw nres tsheb seismograph tom qab nrawm dua-tsav P-nthwv dej thiab hloov chaw hauv av perpendicular mus rau kev taw qhia ntawm kev nthuav tawm
Muaj pes tsawg atoms hauv cov duab molecule tuaj yeem tsim hydrogen bonds nrog dej?
Dr. Haxton hais rau nws cov chav kawm tias cov dej molecule tuaj yeem ua 4 hydrogen bonds, tag nrho lawv nyob rau hauv tib lub dav hlau raws li peb lub atoms
Cov khoom dab tsi ntawm cov dej tso cai rau cov dej los lo rau lub penny?
Kev sib koom tes
Vim li cas cov dej hauv av silted suav hais tias yog lub cim ntawm kev tsim cov dab dej?
Sinkholes yog txhua yam hais txog dej. Dej yaj cov ntxhia hauv pob zeb, tawm hauv seem thiab qhib qhov chaw hauv pob zeb. Dej ntxuav cov av thiab cov seem ntawm cov voids hauv pob zeb. Kev txo qis ntawm cov dej hauv av tuaj yeem ua rau poob ntawm kev txhawb nqa rau cov khoom muag hauv cov pob zeb uas tuaj yeem ua rau tawg
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
