combustion los yog kub hnyiab yog ib qho kev sib txawv ntawm cov tshuaj lom neeg ntawm cov roj thiab cov oxidant nrog rau kev tsim cov cua sov los yog ob qho tib si cua sov thiab lub teeb nyob rau hauv daim ntawv ntawm aglow los yog nplaim taws. Ceev ceev combustion yog ib daim ntawv ntawm combustion nyob rau hauv uas loj npaum li cas ntawm tshav kub thiab lub teeb zog tawm.

Ua raws li qhov kev pom no, dab tsi yog kev txhais lus ntawm kev sib txuas?

combustion yog cov tshuaj tiv thaiv uas tshwm sim ntawm cov roj thiab cov oxidizing tus neeg sawv cev uas tsim lub zog, feem ntau nyob rau hauv daim ntawv ntawm tshav kub thiab lub teeb. combustion yog suav tias yog anexergonic lossis exothermic tshuaj tiv thaiv. Nws tseem hu ua asburning.

Tsis tas li ntawd, 3 hom combustion yog dab tsi? Hom

Kuj paub, dab tsi yog hu ua combustion?

combustion yog cov txheej txheem tshuaj nyob rau hauv uas asubstance reacts sai nrog oxygen thiab muab tawm cua sov. Theoriginal khoom yog hu ua roj, thiab qhov chaw ntawm oxygen yog hu ua cov oxidizer. Cov roj tuaj yeem yog cov khoom, kua, lossis roj, txawm hais tias rau lub dav hlau propulsion cov roj yog cov kua.

Qhov hluav taws kub yog dab tsi?

Tshuaj muaj pes tsawg leeg ntawm Hluav taws kub yog qhov tshwm sim ntawm cov tshuaj tiv thaiv tshuaj hu ua combustion. Ntawm ib qho chaw hauv cov tshuaj tiv thaiv combustion, hu ua ignition point, nplaim taws raug tsim. Cov nplaim taws muaj feem ntau ntawm carbon dioxide, dej vapor, oxygen, thiab nitrogen.
