Raws li tib hom kev sim xws li qhov koj tau ua, cov kws tshawb fawb muaj peev xwm tsim tau peb txoj cai ntawm cov nqi hluav taws xob:
- Tawm tsam nqi sib nyiam.
- Zoo li nqi ntxeev siab rau ib leeg.
- Them nqi cov khoom nyiam cov khoom nruab nrab.
Yog li ntawd, txoj cai ntawm kev them nqi hluav taws xob yog dab tsi?
Tej yam uas muaj tib yam nqi thawb ib leeg deb (lawv tawm tsam ib leeg). Qhov no yog hu ua Txoj cai ntawm Nqi . Tej yam uas muaj electrons ntau dua li cov protons yog qhov tsis zoo raug them , thaum tej yam uas muaj tsawg electrons tshaj protons yog zoo raug them . Tej yam nrog tib yam nqi ntxeev siab rau ib leeg.
Cov nqi hluav taws xob yog dab tsi thiab lawv coj li cas? Hluav taws xob yog lub cev khoom ntawm cov teeb meem uas ua rau nws muaj zog thaum muab tso rau hauv ib qho chaw electromagnetic. Muaj ob hom hluav taws xob : zoo thiab tsis zoo (feem ntau nqa los ntawm protons thiab electrons feem). Zoo li nqi repel ib leeg thiab tsis zoo li nqi sib nyiam.
Ib sab saum toj no, dab tsi yog 3 txheej txheem ntawm kev them nyiaj?
Muaj peb txoj kev nqi ib yam khoom: kev sib txhuam, conduction thiab induction. Kev sib txhuam cuam tshuam nrog cov khoom siv nrog lwm tus, ua rau cov electrons txav ntawm ib qho chaw mus rau lwm qhov.
Yuav tsim cov nqi hluav taws xob li cas?
Hluav taws xob yog qhov tshwm sim ntawm ntau dhau lossis tsis txaus ntawm electrons (tsis zoo raug them particles) piv rau protons (zoo raug them hais). Nws tuaj yeem ua tiav los ntawm cov txheej txheem ntawm rub ob cov ntaub ntawv tawm tsam ib leeg, thaum lub sijhawm cov electrons tsiv ntawm ib qho khoom mus rau lwm qhov.

Txoj cai lij choj ntawm kev txuag hluav taws xob siv li cas rau kev hloov hluav taws xob?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias lub zog tsis tuaj yeem tsim lossis rhuav tshem - tsuas yog hloov los ntawm ib hom ntawm lub zog mus rau lwm qhov. Qhov no txhais tau hais tias ib qho system ib txwm muaj tib lub zog, tshwj tsis yog nws ntxiv los ntawm sab nraud. Tib txoj kev siv lub zog yog hloov lub zog ntawm ib daim ntawv mus rau lwm qhov
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
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
Txoj cai ntawm kev them nqi hluav taws xob yog dab tsi?
Tej yam uas tsis zoo them nqi thiab tej yam uas raug nqi zoo rub rau (tawm) ib leeg. Qhov no ua rau electrons thiab protons lo ua ke los tsim cov atoms. Tej yam uas muaj nqi tib yam thawb ib leeg tawm mus (lawv tawm tsam ib leeg). Qhov no hu ua Txoj Cai Lij Choj
