Tsab xov xwm hais txog Txoj Cai ntawm Kev Txuag Cov Nqi Hluav Taws Xob
Txhua yam khoom siv hauv lub ntiaj teb no yog tsim los ntawm cov atoms. Cov atoms yog tsim los ntawm protons, neutrons, thiab electrons. Proton muaj hluav taws xob zoo; cov electrons muaj hluav taws xob tsis zoo, neutrons tsis muaj hluav taws xob. Hauv lub atom, muaj qee cov electrons, protons, thiab neutrons. Yog tias tus lej ntawm cov electrons sib npaug rau tus lej ntawm cov protons, tag nrho cov hluav taws xob ntawm lub atom yog xoom. Cov atoms zoo li no yog hluav taws xob nruab nrab. Yog tias tus lej ntawm cov electrons ntau dua tus lej ntawm cov protons, ces lub atom yuav raug hluav taws xob tsis zoo. Yog tias tus lej ntawm cov electrons tsawg dua tus lej ntawm cov protons, ces lub atom yuav raug hluav taws xob zoo.
Txhua yam khoom siv yog tsim los ntawm cov atoms, yog li ntawd yog tias cov atoms uas ua rau ib yam khoom muaj cov electrons ntau npaum li cov protons, ces yam khoom ntawd tsis raug them lossis tsis muaj zog. Ntawm qhov tod tes, yog tias cov atoms muaj ntau cov electrons dua li cov protons, ces yam khoom ntawd raug them tsis zoo. Ib yam li ntawd, yog tias cov atoms muaj tsawg dua cov electrons dua li cov protons, ces yam khoom ntawd raug them zoo.
Muaj ntau yam khoom uas pom muaj nyob rau hauv lub neej txhua hnub uas tsis muaj hluav taws xob. Txawm li cas los xij, cov khoom no tuaj yeem hloov mus ua ib yam khoom uas muaj hluav taws xob. Kev hloov cov khoom uas tsis muaj hluav taws xob mus ua hluav taws xob tuaj yeem ua tiav los ntawm kev sib txhuam lossis los ntawm kev siv induction. Hauv txoj kev sib txhuam, cov khoom uas yuav raug them hluav taws xob raug kov nrog lwm yam khoom,
ntawm qhov tsis sib xws, hauv txoj kev induction, cov khoom uas raug them hluav taws xob tsis sib cuag tab sis tsuas yog nyob ze rau lwm yam khoom uas raug them hluav taws xob.
Thaum xub thawj cov yas tsis muaj zog yuav raug them hluav taws xob tom qab txhuam nrog cov plaub hau qhuav. Cov pov thawj tias cov yas tau raug them hluav taws xob yog ob lub pas nrig yas uas tau raug txhuam nrog cov plaub hau qhuav, thiab sib ntaus sib tua. Ob lub pas nrig yas sib ntaus sib tua vim lawv muaj cov nqi zoo sib xws. Raws li tau piav qhia hauv cov ncauj lus ntawm cov nqi hluav taws xob, raws li cov lus pom zoo raws li cov lus qhia ntawm Benjamin Franklin (1706-1790), cov nqi hluav taws xob uas cov yas tuav tau txiav txim siab ua cov nqi tsis zoo. Cov yas raug them tsis zoo kom tag nrho cov electrons hauv cov yas ntau dua li cov protons. Ntawm cov yas tsis muaj zog, nws tuaj yeem xaus lus tias cov electrons ntau dhau uas cov yas muaj tam sim no los ntawm cov plaub hau. Cov electrons hauv cov plaub hau txav mus rau yas thaum lub sijhawm sib txhuam ntawm cov yas thiab cov plaub hau. Cov plaub hau pib tsis muaj zog yog li thaum cov electrons txav mus rau yas, cov plaub hau tsis muaj electrons thiab cov protons ntau dhau. Cov yas dhau los ua cov nqi tsis zoo, thiab cov plaub hau dhau los ua cov nqi zoo.
Tsis muaj hluav taws xob poob thaum lub sijhawm sib txhuam; lub hluav taws xob tsis tsim thaum lub sijhawm sib txhuam, qhov tshwm sim yog kev hloov pauv ntawm lub hluav taws xob. Yas ua rau muaj hluav taws xob tsis zoo, thiab cov plaub hau ua rau muaj hluav taws xob zoo.
Txoj cai lij choj ntawm kev txuag cov nqi hluav taws xob hais tias nyob rau hauv ib lub kaw lus kaw, cov nqi hluav taws xob tsis raug tsim lossis rhuav tshem, tab sis tsuas yog tsiv ntawm ib yam khoom mus rau lwm yam. Tus nqi hluav taws xob tag nrho uas tsim tawm hauv txhua txoj kev yog xoom.
Thaum ib yam khoom muaj hluav taws xob zoo, tib lub sijhawm ntawd lwm yam khoom kuj muaj hluav taws xob tsis zoo, qhov twg txhua yam khoom muaj cov hluav taws xob zoo ib yam. Lub kaw lus kaw hauv cov lus saum toj no tau piav qhia raws li hauv qab no. Piv txwv li, thaum yas thiab plaub hau sib txhuam, nws raug suav hais tias qhov kev hloov pauv ntawm hluav taws xob tsuas yog tshwm sim ntawm yas thiab plaub hau xwb, tsis suav nrog huab cua.
