Vim yog cov cuab yeej tsim khoom, muaj ntau qhov sib txawv ntawm cov yam ntxwv ntawm cov khoom siv. Hauv tshwj xeeb, cov pa roj carbon monoxide yog hygroscopic heev. Thiab yog li ntawd, cov tsev ntawm lawv yuav tsum ua tib zoo ua kom tiav, tiv thaiv cov khoom los ntawm kev sib cuag nrog ib puag ncig sab nraud.
Tab sis hauvnyob rau hauv ob qho tib si, lub hauv paus hnyav tuaj yeem muab faib nrog. Nws tsis muaj teeb meem txawm tias koj siv cov pob zeb ua npuas ncauj lossis cov pob zeb aerated, tab sis cov ntaub ntawv no yog lub teeb, yog li yuav tsis muaj kev kub ntxhov hauv av los ntawm lub tsev zoo li no. Tsis tas li ntawd, nyob rau hauv tag nrho cov no nws yuav ua tau kom txuag tau ntau ntawm thermal rwb thaiv tsev.
