Dej polarity tso cai rau nws kom yaj lwm cov polar tshuaj yooj yim heev. Thaum ib tug polar yam khoom yog muab tso rau hauv dej , qhov zoo kawg ntawm nws cov molecules yog attracted rau qhov tsis zoo kawg ntawm lub dej molecules, thiab vice versa. Nto nro ua rau dej kom clump nyob rau hauv tee dua li kis tawm nyob rau hauv ib tug nyias txheej.

Nyob rau hauv no, yuav ua li cas lub polarity ntawm dej ua rau nws ib tug zoo solvent?

Dej yog a zoo kuab tshuaj vim nws polarity . Qhov loj me me ntawm dej molecules feem ntau tso cai rau ntau yam dej molecules nyob ib puag ncig ib molecule ntawm solute. Ib feem tsis zoo dipoles ntawm cov dej yog attracted rau qhov zoo them cov ntsiab lus ntawm cov solute, thiab vice versa rau qhov zoo dipoles.

Ib tug kuj yuav nug, dab tsi yog qhov tseem ceeb ntawm cov polarity ntawm cov dej? Ntau tseem ceeb , cov polarity ntawm dej Nws yog lub luag haujlwm rau kev ua kom muaj txiaj ntsig zoo rau lwm cov polar molecules, xws li qab zib thiab ionic compounds xws li ntsev. Ionic compounds yaj hauv dej tsim ions. Qhov no yog tseem ceeb nco ntsoov vim feem ntau lom Cov tshuaj tiv thaiv tshwm sim, cov reactants yuav tsum tau yaj hauv dej.

Tsis tas li ntawd, dab tsi yog lub luag haujlwm rau cov tshuaj lom neeg txawv txawv ntawm dej?

Dej molecules yog polar, yog li lawv tsim hydrogen bonds. Qhov no muab dej tshwj xeeb cov khoom , xws li ib tug kuj siab kub point , siab tshwj xeeb kub, cohesion, adhesion thiab ceev.

Cov polarity ntawm cov dej tseem ceeb npaum li cas rau cov lus nug transpiration?

Tag nrho cov roj ntsha molecules yuav yaj hauv dej . Yuav ua li cas yog polarity ntawm cov dej tseem ceeb rau transpiration ? Polarity ua rau cohesion ntawm molecules ntawm dej yog li ntawd lawv rub ib leeg thaum lawv txav mus.
