1. Yog " kov "yog coj los txhais tias ob atoms cuam tshuam ib leeg, ces atoms yog ib txwm kov . Cov electrons uas ua rau lwm tus atom yog khi rau lub nucleus los ntawm lub zog electromagnetic. Atoms yog khi rau hauv molecules, thiab molecules yog khi rau txhua hnub khoom los ntawm lub zog electromagnetic.
Ib yam li ib tug yuav nug, peb puas tau kov ib yam dab tsi tiag tiag?
Tsis muaj yeej muaj dab tsi rau kov , evenelectrons yog ua los ntawm massless zog hais. Peb paub tias splitting ib atom tsim muaj zog heev. Qhov ntawd yog vim tias muaj ntau lub zog ntshiab khi rau hauv "teeb meem" raws li "ntau". Tib lub zog hnyav no hauv qhov chaw me me yog qhov tseem ceeb vim li cas tsis muaj dab tsi puas tau ua tau kov.
Ib yam li ntawd, atoms tau ze li cas? Feem ntau hais lus ze tshaj plaws ntawm ob qho kev sib txuas atomic nuclei yuav kwv yees li ntawm lawv cov VdW radii. Deviations rau txoj cai ntawm tus ntiv tes xoo yuav yuav luag ib txwm ua rau atoms kom nyob deb ntawm ib leeg tshaj li qhov xav tau.
Hais txog qhov no, puas puas tau kov?
Cov khoom yog, los ntawm lawv tus kheej heev, attracted rau cov khoom nrog rau tus nqi rov qab, thiab lawv tawm tsam lwm tus uas zoo sib xws cov khoom . Qhov no tiv thaiv electrons los ntawm puas tau los ntawm kev sib cuag ncaj qha (hauv qhov kev nkag siab atomic thiab kev nkag siab zoo). Lawv cov pob ntawv nthwv dej, ntawm qhov tod tes, ua tau sib tshooj, tab sis tsis tau kov.
Peb puas tuaj yeem kov lub teeb?
Hauv qhov kev xav ntawd teeb tau thaws tawm ntawm koj daim tawv nqaij thiab thiaj li koj muaj ' kov 'nws, mas koj tsuas paub nws vim nws tau mus rau hauv koj ob lub qhov muag thiab tau nqus tau (ua kom puas). Yog li ntawd nyob rau hauv ob txoj kev peb ua tau 'xav' teeb , tab sis tej zaum nws yuav txawv me ntsis rau cov kev coj noj coj ua ntawm kov.

Puas yog Jupiter kub tiag tiag?
Nws kub heev hauv Jupiter! Tsis muaj leej twg paub qhov kub npaum li cas, tab sis cov kws tshawb fawb xav tias nws tuaj yeem yog li 43,000 ° F (24,000 ° C) ze ntawm Jupiter lub chaw, lossis cov tub ntxhais. Jupiter yog tsim los ntawm yuav luag tag nrho ntawm hydrogen thiab helium. Nyob rau saum npoo ntawm Jupiter - thiab nyob rau hauv lub ntiaj teb - cov ntsiab lus yog gases
Puas yog Chimney Sweeping Log tiag tiag ua haujlwm?
Rov qab mus rau lo lus nug ntawm "ua cov chimney cheb cav ua haujlwm tiag tiag?" thawj feem ntawm cov lus teb yog yog, lawv ua haujlwm - rau qee qhov. Cov hom cav no muaj cov tshuaj catalyst nrog tuaj yeem txo cov theem pib ntawm creosote buildup txog 60% nrog rov siv dua
Puas yog magnetic generators tiag tiag?
Permanent-magnet generators yog qhov yooj yim uas lawv yuav tsum tsis muaj qhov system rau kev muab cov teb tam sim no. Lawv muaj kev ntseeg siab heev. Txawm li cas los xij, lawv tsis muaj ib txoj hauv kev los tswj cov zis voltage
Puas yog Stonehenge tiag tiag hauv nruab nrab ntawm Pangea?
Stonehenge yog nyob rau hauv Askiv ntawm Salibury Plain. Nws tau tsim los ntawm tib neeg ~ 5,000 xyoo dhau los. Tsis muaj tib neeg puas tau muaj nyob ntawm Pangaea. Cov teb chaws muaj nyob hauv PreCambrian ua ntej Pangea
Puas yog equator yog lub npe tiag tiag?
Lub Equator thiab Prime Meridian yog qhov chaw tshwj xeeb, yog li lawv yog cov npe tsim nyog thiab yuav tsum tau sau npe. Lawv yuav tsum tau capitalized. Ntawm lwm daim ntawv, kuv yuav hloov 'zoo li' rau 'xws li', raws li Equator thiab Prime Meridian yog kab ntawm latitude thiab longitude
