2 Teb. Cov polarity ntawm dej molecules txhais tau tias molecules ntawm dej yuav nyob sib ze. Qhov no hu ua hydrogen bonding. Polarity ua dej ib qho hnyav hnyav, muab nws lub peev xwm los lo rau nws tus kheej (cohesion), lo rau lwm yam khoom ( adhesion ), thiab muaj qhov nro (vim hydrogen bonding).

Hauv qhov no, dab tsi ua rau adhesion hauv dej?

Adhesion yog qhov attraction ntawm molecules ntawm ib hom rau molecules ntawm ib yam txawv, thiab nws yuav ua tau heev muaj zog rau dej , tshwj xeeb tshaj yog nrog rau lwm cov molecules coj tus nqi zoo lossis tsis zoo. Qhov no yog vim qhov dej molecules muaj zog heev attracted rau ob sab ntawm lub raj dua rau ib leeg.

Ib tug kuj yuav nug, ua li cas dej lub polarity ua rau nws ib tug hnyav hnyav? 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.

Yog li ntawd, polarity cuam tshuam rau dej li cas?

Dej polarity tso cai rau yaj lwm yam polar tshuaj yooj yim heev. Nyob qhov twg dej mus, nws nqa cov tshuaj yaj, cov zaub mov, thiab cov as-ham uas siv los txhawb cov khoom muaj sia. Vim lawv polarity , dej molecules muaj zog attracted rau ib leeg, uas muab dej ib tug siab nto nro.

Dab tsi yog peb qhov tshwj xeeb ntawm cov dej uas tshwm sim los ntawm nws cov polarity?

Cov dej molecules yog polar, yog li lawv tsim hydrogen bonds. Qhov no muab cov khoom tshwj xeeb rau dej, xws li qhov siab kub point , siab tshwj xeeb kub, cohesion, adhesion thiab ceev.
