Koj tuaj yeem qhia peb txog dab tsi tshuaj cov tshuaj tiv thaiv uas nkag mus rau hauv a foob pob hluav taws tso saib? Kev lig kev cai, peb reagents, potassium nitrate, carbon, thiab sulfur, ua hmoov phom. Koj tab tom ua cov tshuaj tiv thaiv combustion tawm ntawm cov khoom siv uas tsim qhov tawg tawg no.
Ua li no, chemistry koom nrog hauv foob pob hluav taws li cas?
Chemistry ntawm foob pob hluav taws Qhov ntawd yog chemistry ib yam! Cov foob pob hluav taws tau lawv cov xim los ntawm cov hlau sib txuas (tseem hu ua hlau ntsev) ntim rau hauv. Sodium compounds muab daj thiab txiv kab ntxwv, piv txwv li, tooj liab thiab barium ntsev muab ntsuab los yog xiav, thiab calcium los yog strontium ua liab.
dab tsi lub zog nyob rau hauv foob pob hluav taws? Cov foob pob hluav taws muaj peev xwm chemical zog , uas transforms rau hauv " kinetic zog xa lub foob pob hluav taws mus rau saum ntuj; qee [ chemical zog ] compresses huab cua sai, ua suab nrov thiab tseem muaj zog dua hloov mus rau hauv lub teeb ntawm ntau xim "(Kev hloov pauv ntawm Tshuaj Zog ,n.d., paj.
Tom qab ntawd, lo lus nug yog, hom tshuaj twg hauv cov foob pob hluav taws?
Hlau ntsev feem ntau siv hauv foob pob hluav taws cov lus qhia muaj xws li: strontium carbonate (liab foob pob hluav taws ), calcium chloride (txiv kab ntxwv foob pob hluav taws ), sodium nitrate (daj foob pob hluav taws ), barium chloride (ntsuab foob pob hluav taws ) thiab tooj liab chloride (xiav foob pob hluav taws ).
Lub foob pob hluav taws ua haujlwm li cas?
Lub ci ci ntsa iab hauv foob pob hluav taws los ntawm kev kub hnyiab me me ntawm cov hlau, xws li hlau lossis hlau filings. Lub fuse teeb tawm ib qho nqi, uas ignites cov hmoov phom. Qhov no propels lub foob pob hluav taws rau saum ntuj. Ib zaug lub foob pob hluav taws yog nyob rau hauv lub ntuj, rab phom nyob rau hauv lub foob pob hluav taws taws.

Lub hom phiaj ntawm kev sim balloon foob pob hluav taws yog dab tsi?
Lub zog mechanical uas thawb lub foob pob hluav taws oraircraft los ntawm huab cua yog hu ua thrust. Hauv qhov kev sim no, koj yuav ua lub foob pob hluav taws zais pa uas yog lub zog los ntawm lub zog. Lub evascaping cua exerts ib tug quab yuam ntawm lub balloon nws tus kheej. Lub zais pa thawb rov qab rau hauv ib qho kev piav qhia los ntawm Newton's Third Law of Motion
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
Cov tshuaj formula ntawm foob pob hluav taws yog dab tsi?
Kev lig kev cai, hmoov phom siv hauv foob pob hluav taws yog ua los ntawm 75 feem pua poov tshuaj nitrate (tseem hu ua saltpeter) tov nrog 15 feem pua charcoal thiab 10 feem pua sulfus; Cov foob pob hluav taws niaj hnub no qee zaum siv lwm cov khoom sib xyaw (xws li sulfurless hmoov nrog ntxiv poov tshuaj nitrate) lossis lwm yam tshuaj
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
Lub co2 hluav taws tua hluav taws puas ua haujlwm ntawm hluav taws kub oxidizer?
Lub tshuab tua hluav taws xob carbon dioxide tsis yog qhov kev xaiv zoo rau kev tua hluav taws oxidizer vim nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tsis suav nrog cov pa oxygen, thiab cov pa oxygen atmospheric tsis xav tau rau hluav taws kub oxidizer.
