Kev sim nplaim taws . Kev sim nplaim taws muaj txiaj ntsig zoo vim tias cov roj excitations tsim cov kab kos npe emission spectrum rau ib lub caij. Thaum cov atoms ntawm cov pa roj los yog vapor zoo siab, piv txwv li los ntawm cua sov lossis los ntawm kev siv hluav taws xob, lawv cov electrons tuaj yeem txav los ntawm lawv lub xeev hauv av mus rau qib siab dua.
Ua kom pom qhov no, lub hom phiaj ntawm kev sim nplaim taws yog dab tsi?
Kev ntsuas nplaim hluav taws yog siv los ntsuas qhov pom ntawm tus kheej ntawm cov hlau tsis paub ntawm cov ntsev ionic raws li tus yam ntxwv xim ntsev tig cov nplaim taws ntawm lub bunsen burner.
Tsis tas li ntawd, qhov ntsuas nplaim hluav taws puas yog? Rau pawg 1 compounds, nplaim taws kuaj feem ntau yog qhov yooj yim tshaj plaws ntawm kev txheeb xyuas cov hlau uas koj tau txais. Rau lwm cov hlau, feem ntau muaj lwm txoj hauv kev yooj yim uas ntau dua ntseeg tau -tab sis nplaim taws kuaj tuaj yeem muab cov lus qhia tseem ceeb raws li qhov yuav tsum tau saib.
Cov xim.

Yog li ntawd, dab tsi tshwm sim ntawm qib atomic thaum kuaj nplaim taws?
Thaum ib atom yog hauv tus nplaim taws , ib electron hauv lub plhaub sab nraud ntawm qhov ntawd atom txais lub zog los ntawm cov nplaim taws thiab dhia mus rau qhov chaw siab dua-lub plhaub plhaub. Thaum ib tug electron hauv lub plhaub muaj zog dua nws tau hais tias yog hauv lub xeev zoo siab. Hluav taws xob hauv zoo siab xeev feem ntau tsis nyob hauv lawv rau ntev heev.
Lub chaw kuaj nplaim taws ua haujlwm li cas?
Cov nplaim taws kuaj yog siv los ntsuas qhov pom ntawm tus kheej ntawm cov hlau tsis paub lossis metalloid ion raws li tus yam ntxwv xim ntsev tig lub nplaim taws ntawm ib tug bunsen burner. Thaum tshav kub kub nplaim taws converts cov hlau ions rau hauv atoms uas ua kom zoo siab thiab emit pom lub teeb.

Vim li cas kuv lub tshuab hluav taws xob tsis tsim hluav taws xob?
Feem ntau ua rau lub tshuab hluav taws xob portable tsis tsim hluav taws xob yog los ntawm kev poob ntawm cov hlau nplaum seem. Generators ua hauj lwm los ntawm kev txav hluav taws xob conductors los ntawm magnetic teb. Koj lub tshuab hluav taws xob tsis muaj hlau nplaum. Thaum cov hlau nplaum seem ploj lawm, lub tshuab hluav taws xob yuav tsis muaj zog thaum pib
Lub teeb ntsuas hluav taws xob siv los kuaj xyuas hluav taws xob li cas?
Lub teeb ntsuas hluav taws xob siv lub teeb tuav hauv ib qho kev sojntsuam txuas nrog tus pas nrig taw tes nrog cov hlau txuas txuas. Qhov kev tsim no yog qhov zoo tshaj plaws rau kev tho cov hlau, kuaj lub fuse lossis kuaj xyuas qhov nqi ntawm lub roj teeb. Yog tias muaj hluav taws xob tam sim no, lub teeb yuav teeb pom tseeb tias lub voj voog muaj zog thiab ua haujlwm zoo
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Lub co2 hluav taws tua hluav taws puas ua haujlwm ntawm hluav taws kub oxidizer?
Lub tshuab tua hluav taws xob carbon dioxide tsis yog qhov kev xaiv zoo rau kev tua hluav taws oxidizer vim nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tsis suav nrog cov pa oxygen, thiab cov pa oxygen atmospheric tsis xav tau rau hluav taws kub oxidizer. Cov tshuaj tua hluav taws qhuav qhuav kuj tseem yuav siv tsis tau rau feem ntau
