Teb thiab piav qhia:
Hom dej uas yog tsawg kawg nkaus yog dej vapor. Dej vapor yog cov qauv ntawm cov pa roj dej , qhov twg cov molecules ntawm dej muaj nyiaj tsawg heev
Tib neeg kuj nug tias, theem dej twg yog qhov tsawg tshaj plaws?
Dej yog densest ntawm 3.98 ° C thiab yog tsawg kawg nkaus ntawm 0 ° C (qhov chaw khov). Dej ceev hloov nrog kub thiab salinity. Thaum twg dej freezes ntawm 0 ° C, ib tug nruj qhib lattice (zoo li lub web) ntawm hydrogen-bonded molecules yog tsim. Nws yog qhov qhib qauv uas ua rau dej khov tsawg ntom tshaj li kua dej.
Ib yam li ntawd, cov khib nyiab tsawg dua li cov kua? Dej khov ntab hauv dej vim nws yog tsawg dua dej. Yog li txhua yam khoom uas muaj qis dua ceev hauv nws khov kho xeev tshaj hauv nws ua kua xeev yuav ntab.

Vim li cas cov dej khov tsawg dua li cov dej ua kua?
Thaum twg dej khov, dej molecules tsim cov qauv crystalline tswj los ntawm hydrogen bonding. Khoom dej , los yog dej khov, yog tsawg dua li cov dej ua kua . Dej khov yog tsawg dua li dej vim hais tias kev taw qhia ntawm hydrogen bonds ua rau cov molecules thawb kom deb, uas ua rau qis dua ceev.

Lub cheeb tsam dej hiav txwv twg muaj biodiversity loj tshaj plaws thiab lub neej dej hiav txwv tshaj plaws?
Epipelagic cheeb tsam nthuav tawm ntawm qhov chaw mus txog 200m nqes. Nws tau txais ntau lub hnub ci thiab yog li muaj cov biodiversity tshaj plaws nyob rau hauv dej hiav txwv. Nws tseem hu ua thaj tsam twilight vim tias lub teeb txwv tsis pub muaj peev xwm lim tau los ntawm cov dej no
Lub teeb hom twg muaj qhov tsawg tshaj plaws?
Thaum nws los txog rau pom lub teeb, cov xim ntau zaus, uas yog violet, kuj muaj lub zog tshaj plaws. Qhov qis tshaj plaws ntawm lub teeb pom kev, uas yog liab, muaj lub zog tsawg tshaj plaws

Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
