Spontaneous combustion ntawm oily rags tshwm sim thaum rag los yog ntaub yog maj mam rhuab mus rau nws ignition point los ntawm oxidation. Ib yam khoom yuav pib tso cua sov thaum nws oxidizes. Qhov no yuav tiv thaiv cov roj los ntawm oxidizing, thiab yog li khaws cov rags los ntawm cua sov thiab igniting.
Ib yam li ntawd, cov roj cav puas tuaj yeem nqus cov rags spontaneously combust?
Lub cev muaj zog roj (thiab dab tsi soaked hauv lub cev muaj zog ) yuav tsawg dua spontaneously combust tab sis nws ua tau tshwm sim yog hais tias tej yam kev mob xwb. Txawm li cas los xij, spontaneous combustion tau tshwm sim yog roj av- soaked rags ncav cuag lawv qhov pib-ignition point ntawm 495 ° F-536 ° F.
Kuj Paub, cov roj dab tsi tuaj yeem ua rau tawg? Linseed roj thiab paj rwb roj yog cov ntaub ntawv uas ua tau ua rau spontaneous combustion thaum muab pov tseg tsis raug.
Hauv qhov no, yog vim li cas oily rags txaus ntshai?
Cov roj uas nquag siv hauv roj -raws li xim thiab stains tso cua sov thaum lawv qhuav. Yog tias tsis muaj cua sov tawm hauv huab cua, nws tsim. Yog vim li cas ib pawg ntawm oily rags tuaj yeem yog txaus ntshai . Thaum tshav kub kub tsim thiab thaum kawg ua rau hluav taws.
Cov roj yam tseem ceeb puas tuaj yeem tawg tau?
Massage cov roj tuaj yeem ua rau hluav taws. Cov ntaub ntawv thiab phuam da dej saturated hauv cov roj tuaj yeem ua rau tawg hauv koj lub tshuab ziab khaub ncaws lossis cia, txawm tias tom qab lawv tau ntxuav lawm.

Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Hom tshuaj tiv thaiv zoo li cas tshwm sim ntawm nws tus kheej lossis spontaneously?
Exothermic cov tshuaj tiv thaiv yuav tshwm sim vim lawv tso lub zog tag nrho (lub "pob" yog dov hauv toj uas tso tawm lub zog). Ob qho kev tshwm sim muaj lub pob me me los kov yeej hu ua lub zog ua kom muaj zog (lub zog xav tau kom tau txais cov molecules txav nrawm txaus los tsoo rau hauv ib leeg thiab hnov mob)
