Ib tug dej molecule muaj peb atoms ; ib tug oxygen atom thiab ob hydrogen atoms , uas yog kev sib raug zoo ua ke zoo li me me hlau nplaum.
Tsuas yog li ntawd, vim li cas thiaj muaj cov khoom hauv kuv cov dej?
Dawb cov khoom los yog huab dej tuaj yeem tshwm sim los ntawm cov khoom siv organic khaws raws li cov dej ntws los hauv av, los yog inorganic cov khoom , xws li cov zaub mov, raug tshem tawm hauv lub dej . Brown sediment nyob rau hauv dej tuaj yeem tshwm sim thaum lub qhov dej tsis ntev los no tau khawb, lossis tuaj yeem qhia tias muaj teeb meem nrog lub qhov dej.
Qhov thib ob, pes tsawg particle nyob hauv h2o? Muaj ob atoms ntawm hydrogen thiab ib atom ntawm oxygen nyob rau hauv txhua dej molecule, ua tus qauv H2O. Yog li, txhua molecule ntawm dej muaj 3 atoms.
Yog li ntawd, dab tsi yog cov khoom siv dej ua los ntawm?
Ib qho atom yog qhov tsawg tshaj plaws particle ntawm cov khoom, xws li oxygen lossis hydrogen. Atoms koom ua ke los tsim cov molecules. A dej molecule muaj peb atoms: ob hydrogen (H) atoms thiab ib tug oxygen (O) atom. Yog vim li cas dej qee zaum hu ua H2O.
Cov dej particle zoo li cas?
Txhua particle , los yog corpuscle, ntawm dej yog ib txwm icosahedron (20-sided geometrical khoom). Qhov no yog dab tsi dej hais zoo li , raws li Plato cov lus piav qhia hauv Timaeus. Hauv qhov chaw yog dej - particle Plato piav txog ntawm 55b, nrog 6 daim duab peb sab scalene ua txhua lub ntsej muag sib npaug ntawm icosahedron.

Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi ntawm cov khoom hauv qab no ntawm dej tso cai rau kab taug kev ntawm dej?
Nws tsis yog tsuas yog dej-cua saum npoo nro uas tso cai rau cov kab taug kev hauv dej. Nws yog kev sib xyaw ua ke ntawm ob txhais ceg tsis raug wetted thiab nto nro. Ob txhais ceg ntawm dej striders yog hydrophobic. Cov dej molecules muaj zog heev attracted rau ib leeg
Cov khoom dab tsi ntawm cov dej tso cai rau cov dej los lo rau lub penny?
Kev sib koom tes
Dab tsi yog qhov txawv ntawm cov khoom tseem ceeb thiab cov kab hauv cov dej hiav txwv?
Ib cag ntawm 12 lub ntsiab lus uas yog cov ntsiab lus tseem ceeb lossis cov ntsiab lus me thiab qee cov ntsiab lus uas yog cov roj yaj, tag nrho lwm cov ntsiab lus yaj hauv dej hiav txwv muaj nyob rau hauv cov ntsiab lus tsawg dua 1 ppm thiab hu ua cov kab hauv qab. Ntau cov kab ke tseem ceeb rau lub neej
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
