Hlawv roj teeb tawm cov pa phem , uas yog irritating rau lub ntsws. Los roj teeb : Tsis txhob raug cov electrolyte xau, nws tuaj yeem ua rau mob hnyav thiab / lossis puas tsuaj rau daim tawv nqaij, mucous membrane lossis ob lub qhov muag.
Ua raws li qhov no, yuav ua li cas yog tias koj nqus pa hauv roj teeb?
Yog a roj teeb ruptures/explosions, cov kua qaub los yog roj tej zaum yuav muaj teeb meem los yog tuag taus yog inhaled nyob rau hauv ib cheeb tsam. Tej zaum yuav ua rau mob hnyav thiab kub hnyiab ntawm qhov ntswg, caj pas thiab ua pa. NYEEM: Yog ingested, lub acid nyob rau hauv lub roj teeb ua rau mob hnyav ntawm qhov ncauj los yog perforation ntawm txoj hlab pas los yog plab.
Kuj Paub, yog lithium roj teeb fumes lom? Cov roj teeb , uas pom nyob rau hauv billions ntawm cov neeg siv khoom xws li smartphones thiab ntsiav tshuaj, tau pom tias xau ntau tshaj 100 tshuaj lom gases xws li carbon monoxide. Cov pa roj, uas muaj peev xwm ua rau tuag taus, tuaj yeem ua rau khaus tawv nqaij, qhov muag thiab qhov ntswg, thiab ua rau muaj kev puas tsuaj rau qhov chaw dav.
Tsis tas li ntawd, cov roj teeb uas tsis hnov tsw muaj teeb meem?
Kev them nyiaj ntau dhau ntawm cov hmoov lead acid roj teeb tuaj yeem tsim hydrogen sulfide. Gas tsis muaj xim, heev lom , flammable thiab muaj cov tsw ntawm cov qe lwj. Raws li cov lus qhia yooj yim, hydrogen sulfide ua phom sij rau tib neeg lub neej yog tias tsw yog pom tau.
Puas yog cov roj ntsha tawg puas tsuaj?
Roj teeb leakage (feem ntau hu ua roj teeb acid) yog qhov phem, corrosive khoom - nws tuaj yeem hlawv koj cov tawv nqaij, paug av, thiab ua kom puas txhua yam khoom uas nws muaj xau rau hauv. Rau txhuas roj teeb , sulfuric acid yog cov txaus ntshai residue, uas yuav tsum tau muaj ntau hom kev ntxuav.

Cov kab mob puas tseem ceeb lossis tsis muaj teeb meem?
Teeb meem yog txhua yam uas muaj huab hwm coj thiab siv qhov chaw. Qhov no suav nrog atoms, cov ntsiab lus, cov khoom sib txuas, thiab txhua yam khoom koj tuaj yeem kov, saj, lossis tsw. Tej yam uas tsis muaj teeb meem yog tsis muaj huab hwm coj los yog lwm yam tsis sau ib lub ntim
Lub kinetic txoj kev xav ntawm cov teeb meem cuam tshuam li cas rau cov kua dej thiab cov pa roj?
Lub kinetic molecular txoj kev xav ntawm cov teeb meem hais tias: Cov teeb meem yog tsim los ntawm cov khoom uas hloov mus tas li. Tag nrho cov khoom muaj lub zog, tab sis lub zog sib txawv nyob ntawm qhov ntsuas kub ntawm cov qauv ntawm cov teeb meem nyob hauv
Puas muaj zog npaum li cas yog cov kua qaub los yog cov hauv paus daws teeb meem?
Qhov ntau ntawm 0 mus rau 14 muab kev ntsuas ntawm kev sib piv lub zog ntawm cov kua qaub thiab cov hauv paus daws teeb meem. Cov dej ntshiab thiab lwm cov kev daws teeb meem nruab nrab muaj tus nqi pH ntawm 7. Tus nqi pH tsawg dua 7 qhia tias cov kua qaub yog acidic, thiab pH tus nqi ntau dua 7 qhia tias cov tshuaj yog qhov yooj yim
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Puas yog khoov ntawm lub teeb tsis nyob ib puag ncig cov teeb meem?
Diffraction yog pom ntawm lub teeb tsis muaj zog tab sis tsuas yog thaum nthwv dej ntsib teeb meem nrog cov wavelengths me me (xws li cov khoom raug tshem tawm hauv peb cov huab cua). Diffraction yog qhov khoov ntawm nthwv dej ncig obstacles thiab qhib. Tus nqi ntawm diffraction nce nrog nce wavelength
