Kev txuag hluav taws xob . Lub hauv paus ntsiab lus uas tag nrho cov nyiaj ntawm zog nyob rau hauv lub kaw lus kaw tseem ib txwm zoo ib yam, tsis muaj leej twg tau ploj los yog tsim nyob rau hauv cov txheej txheem tshuaj lom neeg lossis lub cev lossis hauv kev hloov pauv ntawm ib hom zog mus rau lwm qhov, hauv qhov system.
Tsis tas li ntawd, dab tsi yog txhais los ntawm kev txuag hluav taws xob?
Hauv physics thiab chemistry, txoj cai ntawm kev txuag hluav taws xob hais tias tag nrho zog ntawm ib qho kev sib cais tseem nyob tas li; nws yog hais tias yuav tsum tau txuag lub sij hawm. Txoj cai no txhais tau tias uas zog tsis tuaj yeem tsim lossis rhuav tshem; theej, nws tsuas yog hloov pauv lossis hloov ntawm ib daim ntawv mus rau lwm qhov.
Tsis tas li ntawd, kev txuag hluav taws xob nrog piv txwv yog dab tsi? Kev txuag hluav taws xob yog lub hauv paus ntsiab lus ntawd zog tsis yog tsim los sis puas tsuaj; nws tsuas yog txav los ntawm ib qho mus rau lwm qhov - los ntawm ib hom zog rau lwm tus. Muaj ntau hom zog . Rau piv txwv , xov tooj cua hloov hluav taws xob zog hauv suab zog.
Ib yam li ntawd, tib neeg nug, txoj cai ntawm kev txuag hluav taws xob yog dab tsi?
Cov txoj cai ntawm kev txuag hluav taws xob yog a txoj cai ntawm science uas hais tias zog tsis tuaj yeem tsim lossis rhuav tshem, tab sis tsuas yog hloov ntawm ib daim ntawv mus rau lwm qhov lossis hloov ntawm ib yam khoom mus rau lwm qhov.
Dab tsi yog qhov kev txhais zoo tshaj plaws rau lub zog?
Zog . Feem ntau txhais ntawm zog yog ib txoj hauj lwm uas muaj zog (gravitational, electromagnetic, thiab lwm yam) ua tau. Vim muaj ntau lub zog, zog muaj ntau yam sib txawv (gravitational, hluav taws xob, tshav kub, thiab lwm yam) uas tuaj yeem muab faib ua ob pawg loj: kinetic zog thiab muaj peev xwm zog.

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
Dab tsi yog kauj ruam transformers siv hauv kev xa hluav taws xob hluav taws xob?
Cov hluav taws xob hluav taws xob tau xa mus rau qhov ntev ntawm qhov hluav taws xob siab. Yog li, cov kauj ruam nce transformers yog siv ntawm cov chaw nres tsheb fais fab kom nce qhov hluav taws xob ntawm lub zog whereas cov kauj ruam-down transformers yog siv los txo qhov voltage mus txog 220 V
