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
- Ua kom tiav thiab tsis tiav.
- Smoulding.
- Ceev ceev.
- Kev mob tshwm sim.
- Ntshai.
- Micro-gravity.
- Micro-combustion.
- Stoichiometric combustion ntawm hydrocarbon hauv oxygen.
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.

Intrusion txhais li cas hauv science?
Kev ua los yog ib qho piv txwv ntawm intruding; ib qho tsis zoo siab tuaj ntsib, cuam tshuam, thiab lwm yam: kev nkag mus rau ntawm tus kheej ntiag tug. 2. (Geological Science) a. kev txav ntawm magma los ntawm hauv lub ntiaj teb lub pob zeb mus rau hauv qhov chaw nyob rau hauv lub overlying strata los tsim igneous pob zeb
Yog vim li cas combustion tiav yog zoo dua li tsis tiav combustion?
Tsis tiav combustion tshwm sim thaum cov khoom cua lossis oxygen tsis zoo. Dej tseem tsim, tab sis carbon monoxide thiab carbon yog tsim los ntawm carbon dioxide. Cov pa roj carbon yog tso tawm raws li cov kua qaub. Cov pa roj carbon monoxide yog cov pa tshuaj lom, uas yog ib qho laj thawj vim li cas kev sib xyaw ua tiav yog nyiam rau kev ua tsis tiav
Heterozygous txhais li cas hauv science?
Hauv cov kab mob diploid, heterozygous yog hais txog ib tus neeg uas muaj ob lub alleles sib txawv rau qhov tshwj xeeb. Ib qho allele yog cov qauv ntawm cov noob caj noob ces lossis cov DNA tshwj xeeb ntawm cov chromosome. Ib tsob nroj heterozygous yuav muaj cov alleles hauv qab no rau cov noob zoo: (Rr)
Lub atomic mass txhais li cas hauv science?
Ib qho atomic mass (cim: ma) yog qhov loj ntawm ib qho atom ntawm cov tshuaj lom neeg. Nws suav nrog cov pawg ntawm 3 subatomic particles uas ua rau lub atom: protons, neutrons thiab electrons. 1 atomic mass unit txhais tau tias yog 1/12 ntawm qhov loj ntawm ib qho carbon-12 atom
Br2 txhais li cas hauv science?
Bro·mine. (brō'mēn) Symbol Br. Ib tug ntom, volatile, corrosive, reddish-xim av, nonmetallic kua halogen caij uas tshwm sim raws li ib tug diatomic molecule, Br2 muaj ib tug heev irritating vapor. Tshwj xeeb tshaj yog cais los ntawm brines, nws yog siv nyob rau hauv tsim fumigants, dyes, dej purification compounds, thiab yees duab tshuaj
