Lub cev muaj zog
Xenon tsis muaj xim, tsis muaj ntxhiab tsw gas . Nws muaj qhov kub ntawm -108.13 ° C (-162.5 ° F) thiab melting point ntawm C. Nws yuav zoo li coj txawv txawv los tham txog "lub ntsiab lus melting" thiab "boiling point" gas . Yog li xav txog qhov sib txawv ntawm ob nqe lus no.
Dhau li ntawm no, xenon zoo li cas?
Nws tus lej atomic yog 54a ua yog ib tug tswv cuab ntawm cov noble gases, uas muaj nyob rau hauv pab pawg neeg 18 nyob rau hauv lub periodic rooj. Xenon yog tsis muaj ntxhiab, tsis muaj xim, thiab hnyav dua li huab cua nyob hauv peb qhov chaw. Vim nws muaj peev xwm emit teeb thaum hluav taws xob yog ntxiv, nws tuaj yeem siv rau hauv cov teeb tshwj xeeb.
Kuj Paub, xenon puas tuaj yeem tua koj? Yog koj ua pa ntshiab xenon , nws yuav tsav tawm tag nrho cov pa oxygen thiab tua koj . Yog tias nws yog helium, thaum twg koj mloog, koj lub suab yuav ua siab loj. Yog koj txuas ntxiv ua pa cov roj inert, tsis hais tus twg, koj yuav tuag los ntawm asphyxiation. Koj tsis tuaj yeem tau txais cov pa oxygen, yog tias koj ua pa nkaus xwb inert gas.
Hauv qhov no, dab tsi yog lub cev lub cev ntawm argon?
Lub cev muaj zog Argon yog ib qho tsis muaj xim, tsis muaj ntxhiab, tsis muaj roj. Nws qhov ceev yog 1.784 grams ib liter. Qhov ceev ntawm huab cua, rau kev sib piv, yog hais txog 1.29 grams ib liter. Argon hloov los ntawm cov roj mus rau cov kua ntawm -185.86 ° C (-302.55 ° F).
Lub caij xenon puas tuaj yeem sib nqus tau?
Xenon tam sim no pom nws siv raws li tus dawb keeb . Cov feem ntau zoo tsheb headlamps tam sim no muaj xenon gas nyob rau hauv siab ntawm ob peb ntawm cov cua. Xenon -129, ib qho isotope ruaj khov uas ua rau ib feem peb ntawm ib txwm tshwm sim xenon , hloov tau zoo tagnrho rau siv nyob rau hauv Sib nqus resonance duab.

Lub luag haujlwm ntawm lub cev muaj zog proteins yog dab tsi?
Lub cev muaj zog yog cov molecular motors uas siv ATP hydrolysis txav raws cytoskeletal filaments nyob rau hauv lub cell. Lawv ua tiav ntau lub luag haujlwm hauv cov kab ke lom neeg, suav nrog kev tswj cov zawv zawg ntawm filaments hauv cov leeg nqaij thiab kev sib haum xeeb hauv kev thauj mus los ntawm biopolymer filament lem
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
SFA sawv cev rau dab tsi ntawm lub cev muaj zog?
Service Factor Amps, los yog S.F.A., sawv cev rau tus nqi tam sim no lub cev muaj zog yuav kos thaum khiav ntawm tag nrho Service Factor. Hauv qhov piv txwv nameplate, S.F.A. yog yim amps ntawm 230 volts. Txuas ntxiv tshaj S.F.A. qhia rau ntawm daim ntawv teev npe tuaj yeem ua lub neej luv luv
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
