A ua kua ua los ntawm cov khoom me me vibrating ntawm cov teeb meem, xws li atoms, tuav ua ke los ntawm cov ntawv cog lus intermolecular. Zoo li gas, a ua kua muaj peev xwm ntws thiab nqa cov duab ntawm lub thawv. Feem ntau kua tiv thaiv compression, txawm tias lwm tus ua tau yuav compressed. Dej yog , txog tam sim no, feem ntau ua kua nyob ntiaj teb.
Tsuas yog li ntawd, 3 yam khoom ntawm cov kua yog dab tsi?
Cov molecules tsis muaj ntau qhov chaw nruab nrab ntawm lawv. Cov molecules tsis tuaj yeem nyem ze rau ib leeg. Cov kua dej muaj qhov ntim ruaj khov tab sis tsis muaj qhov ruaj khov. Lawv muaj qhov ntim ruaj khov tab sis lawv tsis muaj qhov ruaj khov lossis qhov tseeb.
Ib yam li ntawd, kev ua kua dej yog dab tsi? Ua kua yog ib hom lus qhib qhov chaw tsim los ntawm Shopify thiab sau hauv Ruby. Nws yog lub hauv paus ntawm Shopify cov ntsiab lus thiab yog siv los thauj cov ntsiab lus dynamic ntawm lub khw muag khoom. Ua kua tau siv ntau lawm ntawm Shopify txij li xyoo 2006 thiab tam sim no tau siv los ntawm ntau lwm cov ntawv thov web hosting.
Tib neeg kuj nug, yog kua ua lus programming?
Ib txhia hais txog Ua kua raws li tus qauv lus , thaum lwm tus tuaj yeem hu nws lub cav template. Nws muaj ib tug syntax (xws li tsoos programming lus ), muaj cov ntsiab lus xws li tso zis, logic, thiab voj, thiab nws cuam tshuam nrog cov sib txawv (cov ntaub ntawv), ib yam li koj xav nrog lub vev xaib-centric lus xws li PHP.
Dab tsi yog 4 yam khoom ntawm cov kua?
Raws li xws li, nws yog ib qho ntawm plaub Cov ntsiab lus tseem ceeb ntawm cov teeb meem (lwm tus yog khoom, roj, thiab ntshav), thiab yog tib lub xeev uas muaj qhov tseeb ntim tab sis tsis muaj qhov ruaj khov. A ua kua yog tsim los ntawm cov khoom me me vibrating ntawm cov teeb meem, xws li atoms, tuav ua ke los ntawm cov ntawv cog lus intermolecular.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Lub kinetic txoj kev xav ntawm cov teeb meem cuam tshuam li cas rau cov kua dej thiab cov pa roj?
Lub kinetic molecular txoj kev xav ntawm cov teeb meem hais tias: Cov teeb meem yog tsim los ntawm cov khoom uas hloov mus tas li. Tag nrho cov khoom muaj lub zog, tab sis lub zog sib txawv nyob ntawm qhov ntsuas kub ntawm cov qauv ntawm cov teeb meem nyob hauv
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
Yuav siv cov tshuaj neutralization li cas los nrhiav cov concentration ntawm cov kua qaub?
Ib qho titration yog ib qho kev sim uas siv cov tshuaj tiv thaiv acid-base neutralization los txiav txim qhov tsis paub txog cov kua qaub lossis lub hauv paus. Qhov sib npaug taw tes yog mus txog thaum tus naj npawb ntawm hydrogen ions sib npaug rau tus naj npawb ntawm hydroxide ions
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
