Cov dej khov qhuav yog daim ntawv khov ntawm cov pa roj carbon dioxide. Nws yog siv feem ntau ua tus neeg ua kom txias. Nws qhov zoo muaj qhov kub qis dua li dej dej khov thiab tsis txhob tso ib qho seem (uas tsis yog qhov xwm txheej los ntawm qhov dej noo hauv qhov chaw).
Kuj nug, dej khov qhuav yog dab tsi thiab nws ua haujlwm li cas?
Cov dej khov qhuav yog daim ntawv ntawm cov pa roj carbon dioxide, cov molecule uas tsiaj ua pa tawm thaum peb nqus thiab cov nroj tsuag nkag mus thaum lawv ua ua photosynthesis. Cov pa roj carbon dioxide yog cov pa ntawm chav sov, thiab nws khov khov ntawm qhov qis dua li dej: -109 degrees Fahrenheit (-78 C).
Kuj Paub, dab tsi yog Qhuav Dej khov teb luv? LUS TEB . Cov dej khov qhuav yog solidified carbon dioxide. Nws yog lub npe vim tias nws zoo li dej khov thiab yog txoj kev txias dua li ib txwm dej khov . Nws nyob qhuav vim nws ncaj qha hloov mus rau cov pa roj carbon dioxide tsis muaj theem ua kua nruab nrab.
Yog li ntawd, dej khov qhuav puas txaus ntshai?
Cov dej khov qhuav , uas yog daim ntawv ruaj khov ntawm cov pa roj carbon dioxide, tsis yog txaus ntshai yog tias nws tau khaws cia thiab siv kom raug. Nws tuaj yeem ua rau muaj kev phom sij vim tias nws txias heev thiab hloov pauv sai rau cov pa roj carbon dioxide. Thaum cov pa roj carbon dioxide tsis muaj tshuaj lom, nws tuaj yeem tsim lub zog lossis tshem tawm huab cua ib txwm muaj, uas ua rau muaj teeb meem.
Puas yog cov dej khov qhuav tib yam li kua nitrogen?
Ua kua nitrogen yog xim tsis muaj ntxhiab, tsis muaj ntxhiab, cov kua liquefied meej nitrogen nrog qhov ntom ntom ntawm 0.807 g/ml ntawm nws qhov kub npau npau (-195.79 ° C (-320 ° F)) thaum dej khov qhuav yog cov khoom tsis sib xws nrog ntom ntawm 97.5189 lb/ft3 ntawm 78.5 ° C (109.3 ° F). Ob leeg kua nitrogen thiab dej khov qhuav tuaj yeem tswj tau qhov kub tsis tshua muaj neeg.

CO2 tuaj yeem ua rau muaj kev phom sij nyob rau hauv Qhov Chaw Nyob Ceev faj thaum siv dej khov qhuav hauv tsev. Cov dej khov qhuav ua rau cov pa roj carbon dioxide, lossis CO2. ('Sublimates' txhais tau tias hloov pauv mus rau hauv cov pa los ntawm cov khoom.) Nws yog qhov txaus ntshai kom siv cov dej khov qhuav hauv chav me lossis chaw tsis muaj qhov cua nkag tau zoo
Yuav muaj dab tsi tshwm sim yog tias koj tso dej khov qhuav rau hauv lub khob ntim?
Khaws Cov Khaub Ncaws Qhuav hauv cov thawv uas muaj insulated. Lub rwb thaiv tsev tuab, qhov qeeb nws yuav sublimate. Tsis txhob Khaws Cov Khaub Ncaws Qhuav hauv lub thawv ntim cua. Sublimation ntawm Cov Khaub Ncaws Qhuav mus rau Cov pa roj carbon Dioxide yuav ua rau lub thawv ntim cua kom nthuav dav lossis tej zaum yuav tawg
Nws siv dej khov qhuav npaum li cas kom xa cov dej khov?
Cov no yog cov thawv xa khoom zoo tshaj plaws muaj thiab tau sim ua lub sijhawm kawg rau qhov muab cov dej khov qhuav. Rau kev xa khoom lossis khaws cov dej khov kom khov, peb pom zoo 1 lb. rau 2 teev, 7-10 lbs. rau 24 teev, 10-12 lbs
Cov pa luam yeeb uas tawm los ntawm cov dej khov qhuav yog dab tsi?
Cov dej khov qhuav yog khov, compressed carbon dioxide gas thiab thaum koj ntxiv rau dej sov, nws ua ke nrog dej los tsim cov pos huab (carbon dioxide thiab dej vapor) uas koj pom bubbling tawm ntawm koj lub tog raj kheej. Ntxiv xab npum mus rau qhov kub hnyiab, ua npuas, dej haus luam yeeb tsim cov txiaj ntsig tshiab tag nrho
Koj puas tuaj yeem khov zaub mov nrog dej khov qhuav?
Dej khov qhuav, ntawm -109.0 ° F lossis -78.5 ° C, yuav khov thiab ua kom khov txhua yam hauv nws lub thawv kom txog thaum nws ua tiav tag nrho. Cov khoom khov no yuav siv sij hawm ntxiv rau thaw vim tias lawv tau txias heev.Yog tias cov dej khov qhuav tso rau saum cov zaub mov (cov dab dej txias), nws yuav ua haujlwm zoo dua
