Ib qho atom yog qhov tsawg tshaj plaws ntawm txhua lub caij uas tseem khaws cov yam ntxwv ntawm lub caij ntawd. Ib daim ntawm ib lub caij uas peb tuaj yeem pom lossis kov yog ua los ntawm ntau, ntau atoms thiab tag nrho cov atoms yog tib yam lawv txhua tus muaj tib tus lej. protons.
Ib yam li ntawd, tib neeg nug, dab tsi yog qhov me me tshaj plaws kom khaws cov khoom ntawm lub caij?
Lus Txhais: atom - Ib atom yog cov tsawg tshaj plaws unit ib keeb uas tseem muaj tag nrho cov khoom ntawm cov khoom ntawd. Feem ntau, ib atom muaj cov protons, neutrons, thiab electrons.
Ib sab saum toj no, dab tsi yog qhov tsawg tshaj plaws ntawm cov ntsiab lus quizlet? Cov me me particle ntawm ib lub caij uas muaj cov khoom ntawm qhov ntawd keeb npe a atom . Ib atom yog lub hauv paus tsev thaiv qhov teeb meem. Tag nrho cov ntsiab lus yog ua los ntawm atoms. Atoms ntawm tib yam keeb zoo ib yam.
Dhau li ntawm no, dab tsi yog qhov me me ntawm cov khoom?
Ib qho atom yog qhov tsawg tshaj plaws ntawm cov teeb meem uas muaj cov khoom ntawm cov khoom. Nws yog tsim los ntawm ib tug ntom core hu ua lub nucleus thiab ib tug series ntawm txheej plhaub nyob los ntawm orbiting electrons. Lub nucleus, tsim los ntawm protons thiab neutrons , yog nyob rau hauv nruab nrab ntawm ib tug atom.
Lub particle twg muab lub ntsiab rau nws cov khoom tshwj xeeb?
protons

Lub npe ntawm cov tshuaj yog dab tsi uas lub zog khaws cia nyob rau hauv thawj theem ntawm photosynthesis?
Cov kev cuam tshuam ntawm lub teeb-dependent siv lub teeb lub zog los ua ob lub molecules uas xav tau rau theem tom ntej ntawm photosynthesis: lub zog cia molecule ATP thiab txo cov khoom siv hluav taws xob NADPH. Nyob rau hauv cov nroj tsuag, lub teeb tshwm sim tshwm sim nyob rau hauv lub thylakoid daim nyias nyias ntawm organelles hu ua chloroplasts
Dab tsi yog lub zog txaus nyiam ntawm ob lub cev ntawm cov khoom sib txawv uas sib cuag nrog ib leeg?
Biology Tshooj 3 Lub Vocabulary A B Polar Molecules nrog ib nrab nqi ntawm qhov xaus. Cov dej molecule muaj cov khoom no. Cohesion Lub zog uas tuav cov molecules ntawm ib qho khoom ua ke. Adhesion Lub zog txaus nyiam ntawm ob lub cev ntawm cov khoom sib txawv uas sib cuag nrog ib leeg
Dab tsi yog qhov kev hloov pauv ntawm cov khoom uas txav ntawm qhov chaw mus rau qhov chaw ntawm - 12 m?
Kev piav qhia: Qhov kev txav ntawm ib qho khoom txav ntawm qhov chaw mus rau qhov chaw ntawm − 12 m yog 12 meters. Qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov siab tshaj plaws txoj hauj lwm yog hu ua displacement ntawm ib yam khoom. Qhov siab tshaj plaws kev hloov pauv ntawm cov khoom nyob rau hauv ib nthwv dej yog hu ua crest thiab qhov tsawg kawg nkaus hloov pauv yog hu ua trough
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
