Greenhouse Effect . Cov tsev cog khoom nyhuv hais txog cov xwm txheej uas luv luv wavelengths ntawm pom lub teeb los ntawm lub hnub dhau los ntawm qhov nruab nrab pob tshab thiab yog absorbed, tab sis ntev dua wavelengths ntawm infrared rov- hluav taws xob los ntawm cov khoom cua sov tsis tuaj yeem dhau los ntawm qhov nruab nrab.
Nyob rau hauv kev hwm rau qhov no, hom hluav taws xob twg ua rau lub tsev cog khoom nyhuv?
GREENHOUSE EFFECT Lub tsev xog paj hauv cov huab cua (xws li dej vapor thiab carbon dioxide) nqus feem ntau ntawm lub ntiaj teb emitted longwave infrared hluav taws xob , uas heats qhov qis cua.
Ib yam li ntawd, lub tsev cog khoom nyhuv luv teb yog dab tsi? Cov Luv teb : Cov tsev cog khoom nyhuv yog txheej txheem uas tshwm sim thaum cov pa nyob rau hauv lub ntiaj teb huab cua cuab lub hnub tshav kub. Cov txheej txheem no ua rau lub ntiaj teb sov dua li nws yuav tsis muaj cua. Cov tsev cog khoom nyhuv yog ib yam uas ua rau lub ntiaj teb zoo nyob.
Tsis tas li ntawd, qhov ntev wavelength hluav taws xob ua rau lub tsev cog khoom zoo li cas?
Qhov tawm ntev wavelength hluav taws xob emitted los ntawm lub ntiaj teb yog ib feem kom tag absorbed los ntawm cov tsev xog paj dej vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), thiab tropospheric ozone (O3).
Yuav ua li cas ua rau lub tsev xog paj cov lus teb?
Cov tsev cog khoom nyhuv tshwm sim thaum muaj tseeb cov pa nyob rau hauv lub ntiaj teb huab cua (cua nyob ib ncig ntawm lub ntiaj teb) ntxiab infrared hluav taws xob. Qhov no ua cov ntiaj chaw ua kom sov, zoo ib yam li nws ua rau tsev cog khoom ua kom sov.

Lub ntsiab txhais ntawm lo lus hluav taws xob hluav taws xob yog dab tsi?
Npe. Cov hluav taws xob hluav taws xob txhais tau tias yog hluav taws xob hluav taws xob uas tso cai rau kev ua haujlwm kom tiav. Ib qho piv txwv ntawm lub zog hluav taws xob yog lub zog los ntawm lub qhov hluav taws xob ntsaws. YourDictionary txhais thiab siv piv txwv
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
