Qhov sib txawv tseem ceeb ntawm combustion thiab tawg yog qhov combustion yog tshuaj lom neeg cov tshuaj tiv thaiv uas ua rau kub thiab gases maj mam rau ib lub sij hawm, qhov tawg yog cov tshuaj tiv thaiv uas ua rau kub thiab gases sai sai.
Kev sib xyaw thiab tawg yog ob qho tshuaj lom neeg tseem ceeb hauv kev siv lub cev. Ob txheej txheem no zoo sib xws hauv cov khoom kawg uas lawv muab. Txawm li cas los xij, lawv txawv ntawm ib qho tshuaj, thiab peb tuaj yeem yooj yim paub qhov sib txawv ntawm qhov tawg.
Dab tsi yog combustion?
Combustion yog cov tshuaj tiv thaiv uas cov tshuaj tiv thaiv nrog oxygen, tsim lub zog. Ntawm no, lub zog yog tsim nyob rau hauv ob hom xws li lub teeb lub zog thiab lub zog kub. Peb hu qhov no "hlawv." Lub teeb lub zog zoo li nplaim taws, thaum lub zog hluav taws xob tso rau hauv ib puag ncig.
Daim duab 01: Kev sib xyaws
Muaj ob hom kev sib xyaw ua kom tiav thiab tsis tiav combustion. Nyob rau hauv tag nrho combustion, muaj ntau tshaj ntawm cov pa, thiab nws muab ib tug tsawg tus naj npawb ntawm cov khoom, piv txwv li thaum peb hlawv roj, ua kom tiav combustion muab carbon dioxide thiab dej nrog tshav kub zog. Tsis tiav combustion, ntawm qhov tod tes, yog ib feem ntawm cov txheej txheem kub hnyiab uas muab ntau cov khoom tom kawg ntawm cov tshuaj tiv thaiv. Ntawm no, siv cov pa oxygen tsawg tsawg; Yog hais tias peb hlawv roj, tsis tiav combustion ntawm roj muab carbon dioxide, carbon monoxide, thiab dej nrog cua sov. Kev tsim hluav taws xob los ntawm kev sib txuas yog qhov tseem ceeb hauv kev lag luam, thiab cov txheej txheem no tseem ceeb heev los tsim hluav taws.
Kev tawg yog dab tsi?
Ib qho tawg yog qhov nthuav dav ntawm lub ntim uas cuam tshuam nrog kev tawm dag zog sab nraud tawm ntawm lub zog. Qhov no feem ntau yuav siv qhov chaw nrog rau qhov tsim ntawm qhov kub thiab txias thiab tso tawm cov roj cua siab. Detonations yog supersonic explosions uas tsim los ntawm muaj zog explosives. Lub zog tso tawm los ntawm hom kev tawg no nyiam taug kev los ntawm kev poob siab tsis muaj zog. Ntxiv mus, muaj subsonic explosions. Cov no yog tsim los ntawm cov khoom tawg qis. Qhov tawg nyob rau hauv cov khoom tawg qis no tshwm sim los ntawm cov txheej txheem combustion qeeb: deflagration.
Daim duab 02: Kev tawg
Feem ntau, lub zog tso tawm los ntawm kev tawg feem ntau yog nyob rau ntawm qhov chaw ntawm qhov tawg. Thaum xav txog qhov nrawm ntawm cov tshuaj tiv thaiv tawg, peb tuaj yeem yooj yim paub qhov txawv ntawm cov tshuaj tiv thaiv combustion. Nyob rau hauv ib txwm combustion cov tshuaj tiv thaiv, tshav kub yog generated, thiab ib co gases raug tso tawm; Txawm li cas los xij, thaum lub sij hawm tawg, tiam ntawm cov cua sov thiab tso tawm cov pa roj tshwm sim sai heev. Qhov kev tso tawm sai sai ntawm cov cua sov thiab cov pa hluav taws xob tuaj yeem ua rau lub tsev ntawm lub siab ceev, uas ua rau tawg. Tsis tas li ntawd, qhov tshwm sim tawg pib nrog kev siv cov cua sov, kev poob siab, lossis cov catalyst. Fragmentation yog ib kauj ruam tseem ceeb uas tshwm sim thaum lub sij hawm tawg. Cov kauj ruam no suav nrog cov tsub zuj zuj thiab kev kwv yees ntawm cov khoom raws li qhov tshwm sim ntawm qhov tawg siab heev. Cov khoom tawg no yog tsim los ntawm cov khoom siv xws li iav, cov khoom siv vov tsev, thiab lwm yam. Tsis tas li ntawd, kev tawg tuaj yeem tshwm sim los ntawm kev puas tsuaj ntawm cov khoom tawg thiab lwm yam khoom xoob uas tsis vaporized thaum tawg.
Dab tsi yog qhov Zoo sib xws ntawm Kev Sib Txuas thiab Kev tawg?
- Combustion and explosion generate heat energy.
- Ob qhov kev tawm tsam tso tawm roj.
- Lawv muaj txiaj ntsig zoo li lub zog.
Qhov txawv ntawm Kev Sib Txuas thiab Kev tawg yog dab tsi?
Kev sib xyaw thiab tawg yog ob qho tshuaj lom neeg tseem ceeb hauv kev siv lub cev. Ob txheej txheem no zoo sib xws hauv cov khoom kawg uas lawv muab. Qhov sib txawv tseem ceeb ntawm combustion thiab tawg yog tias combustion yog tshuaj lom neeg cov tshuaj tiv thaiv uas ua rau kub thiab gases maj mam rau ib lub sij hawm, qhov tawg yog cov tshuaj tiv thaiv uas ua rau kub thiab gases sai sai nyob rau hauv ib qho instant.
Cov hauv qab no qhia txog qhov sib txawv ntawm kev sib tsoo thiab tawg hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Combustion vs Explosion
Combustion yog cov tshuaj tiv thaiv uas cov tshuaj tiv thaiv nrog oxygen, tsim lub zog. Kev tawg yog ib qho kev nthuav dav sai ntawm lub ntim uas cuam tshuam nrog kev tawm dag zog sab nraud tawm ntawm lub zog. Qhov sib txawv tseem ceeb ntawm combustion thiab tawg yog tias combustion yog tshuaj lom neeg cov tshuaj tiv thaiv uas ua rau kub thiab gases maj mam rau ib lub sij hawm, qhov tawg yog cov tshuaj tiv thaiv uas ua rau kub thiab gases sai / sai sai nyob rau hauv ib qho instant.
