Thaum dej yog qhov hnyav, cov kev daws teeb meem yog hu ua dej kev daws teeb meem.
Tsis tas li ntawd, dab tsi yog qhov kev daws teeb meem hauv cov dej uas hnyav?
Ib qho dej daws yog a tshuaj nyob rau hauv uas dej yog cov kuab tshuaj . Ib NaCl daws yog aqueous daws.
Ib sab saum toj, yog vim li cas dej yog polar hnyav? Dej ua a polar kuab tshuaj vim hais tias nws tuaj yeem cuam tshuam rau qhov zoo lossis qhov tsis zoo ntawm cov hluav taws xob hluav taws xob ntawm tus solute. Qhov tsis zoo me ntsis nyob ze ntawm cov pa atom nyiam cov hydrogen atoms nyob ze ntawm dej los yog qhov zoo-charged cheeb tsam ntawm lwm cov molecules.
Ib sab saum toj no, dej ua haujlwm li cas?
Dej muaj peev xwm ntawm dissolving ntau yam khoom sib txawv, uas yog vim li cas nws yog xws li ib tug zoo kuab tshuaj . Thiab, dej hu ua "universal kuab tshuaj "vim nws dissolves ntau tshaj li lwm yam kua. Qhov no tso cai rau cov dej molecule los ua attracted rau ntau lwm yam sib txawv ntawm molecules.
Txoj kev daws teeb meem yog dab tsi?
Kev tsim ntawm a daws los ntawm cov kuab tshuaj thiab cov kuab tshuaj yog lub cev txheej txheem , tsis yog chemical. Cov khoom uas tsim cov theem sib cais yog immiscible. Kev daws yog qhov txheej txheem nyob rau hauv uas solute hais yog surrounded los ntawm hnyav molecules. Thaum cov kuab tshuaj yog dej, lub txheej txheem hu ua hydration.

Cov kua dej thiab hom kua dej yog dab tsi?
Cov kua dej tuaj yeem muab faib ua plaub yam yooj yim. Cov kua dej zoo tagnrho. Cov kua dej tiag tiag. Newtonian kua dej. Tsis yog-Newtonian Fluid
Cov polarity cuam tshuam li cas dej lub luag haujlwm ua cov kuab tshuaj?
Dej Cov Khoom Uas Muaj Zog. Dej, uas tsis yog tsuas yog dissolves ntau lub tebchaw tab sis kuj dissolves ntau tshaj li lwm yam kua, suav hais tias yog lub universal hnyav. Polar molecule nrog ib nrab-zoo thiab tsis zoo nqi, nws yooj yim dissolves ions thiab polar molecules
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 cov qauv ntawm cov dej ua rau nws muaj cov kuab tshuaj zoo?
Dej muaj peev xwm yaj ntau yam khoom sib txawv, uas yog vim li cas nws yog ib qho hnyav hnyav. Cov dej molecules muaj lub ntsiab lus ntawm cov pa oxygen thiab hydrogen atoms - ib sab (hydrogen) muaj qhov zoo hluav taws xob thiab lwm sab (oxygen) muaj qhov tsis zoo
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
