Oobleck yog cov kua uas tsis yog-Newtonian, ib lo lus rau cov kua uas hloov viscosity (yuav yooj yim npaum li cas lawv ntws) nyob rau hauv kev ntxhov siab. Lub zog quab yuam no pab cov slurry ntws, raws li cov particles nyiam ib txheej ntawm cov kua nruab nrab ntawm ces. Tab sis thaum sib tov ua ke, kev sib txhuam yuav siv sij hawm dhau thiab cov khoom txav mus zoo li ib tug khov.
Kuj nug, vim li cas Oobleck ob leeg yog cov khoom thiab cov kua?
Hauv oobleck ua , tus kuj loj khov kho cornstarch molecules tsim cov saw ntev. Cov dej me me ntws dhau ib leeg thiab nruab nrab ntawm pob kws molecules tso cai rau cov saw hlau xaub thiab ntws ncig ib leeg. Qhov no yog vim li cas oobleck ua coj zoo li ib ua kua thaum nws tsis nyob hauv siab.
Tsis tas li ntawd, Oobleck zoo li cov kua li cas? Oobleck . Oobleck yog ib qho kev ncua ntawm pob kws thiab dej uas tuaj yeem coj tus cwj pwm nyiam ib lub cev los yog a ua kua nyob ntawm seb koj siv zog npaum li cas. Sim tuav qee yam ntawm koj txhais tes, thiab nws yuav tsim ib lub pob khoom hauv koj lub xib teg kom txog thaum koj tso lub siab. Tom qab ntawd, nws yuav ntws tawm ntawm koj cov ntiv tes.
yog Oobleck khoom lossis kua?
Oobleck yog ib tug uas tsis yog-Newtonian kua dej ; nws muaj zog ntawm ob qho tib si kua thiab cov khoom khib nyiab . Koj tuaj yeem maj mam muab koj txhais tes rau hauv nws zoo li ib qho ua kua , tab sis yog tias koj nyem lub oobleck ua los yog xuas nrig ntaus nws, nws yuav hnov khov kho . Lub npe oobleck ua los ntawm Dr.
Thaum Oobleck coj zoo li cov khoom zoo li cas Koj puas xav tias nws yog thiab vim li cas?
Thaum twg koj nyem, dov, lossis ua rau lawv ntxhov siab, cov "atom chains" yuav tau entangled thiab daim ntawv ib khov kho ! Tshuaj zoo li Oobleck raug hu ua "non-Newtonian fluids" vim tias lawv tsis muaj cov khoom zoo li qub cov khoom khib nyiab los yog kua.

Vim li cas lub suab mus nrawm dua hauv cov khoom hauv cov kua?
Lub suab mus nrawm dua hauv cov khoom hauv cov kua, thiab sai dua hauv cov kua ntau dua hauv cov pa. Qhov no yog vim qhov ceev ntawm cov khib nyiab siab dua li cov kua uas txhais tau hais tias cov khoom nyob ze ua ke
Vim li cas cov kua siv lead ua kua hloov xim nrog kub?
Cov molecules hauv cov kua siv lead ua kua tuaj yeem txav mus los ntawm nws tus kheej, xws li hauv cov kua, tab sis nyob twj ywm me ntsis, xws li hauv cov khoom siv lead ua (khoom). Cov kua siv lead ua kua no teb rau kev hloov pauv ntawm qhov kub thiab txias los ntawm kev hloov xim. Raws li qhov kub thiab txias, lawv cov xim hloov ntawm liab mus rau txiv kab ntxwv, daj, ntsuab, xiav, thiab ntshav
Dab tsi yog qhov zoo sib xws ntawm cov khoom thiab cov khoom sib txuas?
Cov ntsiab lus thiab cov tebchaw yog cov tshuaj homogeneous nkaus xwb thiab lawv muaj qhov sib xyaw tas li thoob plaws. Cov ntsiab lus thiab cov tebchaw tsis tuaj yeem sib cais rau hauv lawv cov khoom sib xws los ntawm kev siv lub cev. Cov tshuaj thiab cov khoom sib tov yog tsim los ntawm cov khoom sib txawv lossis cov atom sib txawv
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
