Hydrogen bonds hauv dej muab ntau yam txiaj ntsig zoo rau dej : cohesion (tuav dej molecules ua ke), cov cua kub tshwj xeeb (nqus cua sov thaum tawg, tso cua sov thaum tsim; txo qhov kub hloov pauv), kub kub ntawm vaporization (ntau hydrogen bonds yuav tsum tau tawg thiaj li yuav evaporate dej )

Kuj nug, hydrogen bonds cuam tshuam rau dej li cas?

Cov dej siab kub muaj peev xwm yog a vaj tse tshwm sim los ntawm hydrogen kev sib raug zoo ntawm dej molecules. Thaum tshav kub yog absorbed, hydrogen bonds tawg thiab dej molecules ua tau txav tau ywj siab. Thaum kub ntawm dej txo, cov hydrogen bonds raug tsim thiab tso tawm ntau lub zog.

Ib sab saum toj no, yuav ua li cas tshwm sim tsis muaj hydrogen bonding? Hydrogen bonds ua kom qhov txo qis ntawm qhov kub siab tshaj plaws hauv cov dej loj. Txawm li cas los xij, tsis muaj hydrogen bonds , dej hauv dej hiav txwv thiab pas dej yuav pib sai sai vim qhov poob ntawm qhov kub npau npau - ua rau muaj teeb meem loj rau lub neej hauv ntiaj teb.

Kuj paub, vim li cas hydrogen bonding hauv dej tseem ceeb rau lub neej?

Lub xub ntiag ntawm hydrogen bonds kuj ua dej molecules ntau 'nplaum' los yog nyob rau hauv scientific cov ntsiab lus cohesive thiab nplaum. Cov nqi me me ntawm cov dej molecules tso cai rau lawv los ua ke uas yog vim li cas dej muaj 'daim tawv' uas cov kab me tuaj yeem taug kev, thiab piav qhia vim li cas dej tuaj yeem nqus tau straw yooj yim heev.

Dab tsi yog 3 yam tseem ceeb ntawm cov dej?

Lub ntsiab cov khoom ntawm dej yog nws polarity, cohesion, adhesion, nto nro, siab tshwj xeeb kub, thiab evaporative txias. A dej molecule yog me ntsis them rau ntawm ob kawg. Qhov no yog vim muaj oxygen ntau electronegative tshaj hydrogen.
