A zoo li qub charge tshwm sim thaum ob qhov chaw kov ib leeg thiab cov electrons txav ntawm ib yam khoom mus rau lwm qhov. Ib qho ntawm cov khoom yuav muaj tus nqi zoo thiab lwm qhov tsis zoo. Yog tias koj rub ib yam khoom sai sai, zoo li lub zais pa, lossis koj txhais ko taw ntawm cov ntaub pua plag, cov no yuav tsim kom muaj nqi ntau dua.
Tsuas yog li ntawd, dab tsi yog qhov hluav taws xob zoo li qub hauv cov lus yooj yim?
hluav taws xob zoo li qub txhais tau hais tias qhov nce ntawm cov nqi hluav taws xob nyob rau saum npoo ntawm cov khoom. Tus nqi hluav taws xob no tseem nyob ntawm ib qho khoom kom txog thaum nws ntws mus rau hauv av, lossis poob nws cov nqi sai sai los ntawm a tso tawm . Kev pauv pauv tuaj yeem tshwm sim hauv cov xwm txheej zoo li thaum cov khoom sib txawv raug rubbed thiab sib cais.
Kuj Paub, koj piav li cas zoo li qub? Lub phenomenon ntawm zoo li qub hluav taws xob xav tau kev sib cais ntawm qhov zoo thiab qhov tsis zoo. Thaum ob cov ntaub ntawv nyob rau hauv kev sib cuag, electrons yuav txav los ntawm ib yam khoom mus rau lwm yam, uas tawm ib tug ntau tshaj ntawm zoo nqi ntawm ib yam khoom, thiab ib tug sib npaug zos nqi rau lwm yam.
Yog li ntawd, koj yuav ua li cas qhia txog hluav taws xob zoo li qub?
Cov tub kawm kuj yuav hais li ntawd thiab hluav taws xob zoo li qub yog tsim thaum ob yam khoom raug rubbed ua ke, ua rau ib qho khoom tso tawm lossis nce electrons. Qhov no tuaj yeem tshwm sim los ntawm kev hnav lub tsho, taug kev ntawm cov ntaub pua plag, lossis tawm ntawm lub tsheb. Qhov tsis sib npaug ntawm cov nqi ntawm cov khoom ua rau hluav taws xob zoo li qub.
Tus nqi hluav taws xob zoo li cas tsim?
hluav taws xob zoo li qub yog qhov tshwm sim ntawm qhov tsis sib xws ntawm qhov tsis zoo thiab qhov zoo nqi hauv ib yam khoom. Cov no nqi tuaj yeem tsim nyob rau ntawm qhov chaw ntawm ib qho khoom mus txog thaum lawv nrhiav tau txoj hauv kev tso tawm lossis tawm mus. Rubbing qee cov ntaub ntawv tawm tsam ib leeg tuaj yeem hloov tsis zoo nqi , los yog electrons.

Cov kab hluav taws xob ua li cas qhia tias hluav taws xob muaj zog?
Lub zog ntawm cov hluav taws xob hluav taws xob nyob ntawm qhov chaw them nqi, tsis yog ntawm qhov kev xeem nqi. Ib kab tangent mus rau ib kab teb qhia txog kev taw qhia ntawm hluav taws xob ntawm qhov taw tes. Qhov twg cov kab teb nyob ze ua ke, cov hluav taws xob hluav taws xob muaj zog dua qhov uas lawv nyob deb
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
Koj piav qhia txog photosynthesis li cas rau cov menyuam kawm ntawv preschool?
Photosynthesis - Lub voj voog ntawm cov nroj tsuag thiab lawv ua li cas lub zog! Lub hnub (lub teeb lub zog), dej, minerals thiab carbon dioxide yog absorbed los ntawm cov nroj tsuag. Cov nroj tsuag ces siv lawv los ua cov piam thaj / qab zib, uas yog lub zog / khoom noj rau cov nroj tsuag
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
