Thaum twg gas hlawv nws feem ntau ua ke nrog oxygen kom muab carbon dioxide, dej thiab lwm yam nrog rau kev tso tawm ntawm lub zog. Los ntawm kev txhais, nws yog a tshuaj hloov.
Yog li ntawd, puas yog hluav taws kub hloov tshuaj?
Teb thiab piav qhia: Yog, hlawv roj av yog a tshuaj hloov vim thaum roj av yog ignited, dej thiab carbon dioxide raug tsim.
Puas yog daim ntawv hlawv yog tshuaj lom neeg lossis hloov lub cev? Hlawv ib daim ntawv yog technically hu ua combustion. Nws sawv cev ib tshuaj tiv thaiv yog li cov carbon compounds nyob rau hauv lub ntawv yog oxidized rau hauv cov tshuaj sib txawv xws li carbon dioxide thiab dej vapor. Qhov no yog ib tshuaj hloov.
Xav txog qhov no, hom tshuaj tiv thaiv dab tsi yog hlawv ntawm cov pa roj carbon monoxide?
Nqe lus piav qhia: thaum methane ( natural gas ) reacts nrog oxygen, qhov tshwm sim yog carbon di-oxide thiab dej, nrog rau cov cua sov, li no ua rau nws exothermic. tshuaj tiv thaiv.
Thaum cov roj methane hlawv nws puas yog kev hloov tshuaj?
Ib qho piv txwv ntawm ib qho yooj yim tshuaj hloov yog cov kub ntawm methane . Methane yog lub ntsiab ntawm ntuj gas , yog hlawv nyob rau hauv ntau lub tsev cua sov. Thaum kub , methane ua ke nrog cov pa oxygen hauv huab cua kom tsim tau qhov sib txawv kiag li tshuaj tshuaj, nrog rau cov cov pa carbon dioxide thiab dej vapor.

Puas yog huab cua hloov pauv lub cev lossis tshuaj lom neeg?
Kev hloov ntawm lub xeev yog kev hloov ntawm lub cev hauv qhov teeb meem. Lawv yog cov kev hloov pauv uas tsis hloov qhov teeb meem tshuaj pleev lossis tshuaj lom neeg. Piv txwv li, thaum huab cua hloov mus rau dej vapor, nws tseem yog dej thiab tuaj yeem hloov rov qab mus rau cov kua dej dua
Puas yog tshuaj lom neeg ntom ntom lossis lub cev hloov pauv?
Kev piav qhia: Cov khoom siv tshuaj lom neeg tsuas yog tsim los ntawm kev ua cov tshuaj tiv thaiv (kub ntawm combustion, flash point, enthalpies ntawm kev tsim, thiab lwm yam). Qhov ntom tuaj yeem tsim tau yooj yim los ntawm kev txiav txim siab qhov ntim ntawm cov khoom, tsis muaj kev cuam tshuam, yog li nws aphysical khoom
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. Cov tshuaj tua hluav taws qhuav qhuav kuj tseem yuav siv tsis tau rau feem ntau
Puas muaj kev hloov pauv ntawm lub cev lossis tshuaj lom neeg thaum muaj suab thaj yaj hauv dej?
Dissolving qab zib hauv dej yog ib qho piv txwv ntawm kev hloov lub cev. Nov yog vim li cas: Kev hloov tshuaj lom neeg tsim cov khoom siv tshuaj tshiab. Txhawm rau kom qab zib hauv dej los ua cov tshuaj hloov pauv, ib yam tshiab yuav tsum tau ua. Yog tias koj evaporate cov dej los ntawm cov kua qab zib-dej, koj nyob nraum nrog qab zib
