Cov yaj ntawm cov khoom siv quav ciab ua kua siv quav ciab thiab evaporation ntawm cov kua siv quav ciab ua form siv quav ciab vap yog kev hloov ntawm lub cev . Cov kub ntawm siv quav ciab vap yog a tshuaj hloov . Cov siv quav ciab vapor reacts nrog oxygen hauv huab cua los tsim cov khoom tshiab xws li carbon dioxide thiab tshauv.
Ib sab saum toj no, puas yog lub cev hloov pauv lossis hloov tshuaj lom neeg vim li cas? Hlawv ntoo yog a tshuaj hloov raws li cov khoom tshiab uas hloov tsis tau rov qab (xws li carbon dioxide) raug tsim. Piv txwv li, yog ntoo yog hlawv nyob rau hauv ib lub qhov cub, tsis muaj ntoo lawm, tab sis tshauv. Sib piv: Kev hloov ntawm lub cev - Qhov opposite ntawm a tshuaj hloov yog a hloov lub cev.
