Lub zog uas lub tshuaj tiv thaiv cov khoom tuaj yeem ua tau siv kom sov dej, ua zaub mov, tsim hluav taws xob lossis txawm tias lub tsheb fais fab. Cov khoom ntawm combustion tshua yog cov tebchaw ntawm oxygen, hu ua oxides.
Ib sab ntawm qhov no, dab tsi yog qhov piv txwv ntawm lub neej tiag tiag ntawm kev tawm tsam combustion?
Hlawv ntoo hauv qhov hluav taws kub yog ib qho piv txwv ntawm cov tshuaj tiv thaiv combustion. Nyob rau hauv cov tshuaj tiv thaiv combustion, cov carbohydrates hauv ntoo ua ke nrog oxygen los ua dej thiab carbon dioxide. Cov tshuaj tiv thaiv no muaj zog heev, thiab nws ua kom sov thiab lub teeb thaum nws tso tawm lub zog.
Tsis tas li ntawd, qee qhov piv txwv ntawm combustion yog dab tsi? Piv txwv ntawm Kev Sib Tham Sib Tham
- combustion ntawm methane. CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g)
- Hlawv ntawm naphthalene.
- Combustion ntawm ethane.
- combustion ntawm butane (feem ntau pom nyob rau hauv lighters)
- combustion ntawm methanol (tseem hu ua ntoo cawv)
- combustion ntawm propane (siv hauv cov roj grills, qhov cub, thiab qee qhov cooks)
Hauv qhov no, vim li cas cov tshuaj tiv thaiv combustion tseem ceeb?
Cov tshuaj tiv thaiv combustion yog ib qho heev tseem ceeb chav kawm ntawm chemical cov tshuaj tiv thaiv . Cov no cov tshuaj tiv thaiv yog qhov tseem ceeb rau peb lub neej txhua hnub. A combustion tshuaj tiv thaiv tshwm sim thaum muaj roj thiab oxygen teb , ua cua sov lossis cua sov thiab lub teeb. Lwm yam recognizable combustion tshua suav nrog ib lub tswm ciab hlawv los yog ib qho chaw ua si zoo nkauj.
Yuav ua li cas yog ib co piv txwv ntawm combustion tshuaj tiv thaiv?
Cov tshuaj tiv thaiv combustion tshwm sim thaum oxygen reacts nrog lwm yam khoom thiab muab tawm cua sov thiab lub teeb. Hlawv thee, methane gas, thiab sparklers yog txhua yam piv txwv ntawm combustion tshua . Qhov tseem ceeb, txhua yam tshuaj tiv thaiv uas yuav hlawv ib yam dab tsi yog ib combustion tshuaj tiv thaiv.
