Cov dej polarity tso cai rau yaj lwm yam polar tshuaj yooj yim heev. Thaum a polar Cov khoom yog muab tso rau hauv dej, qhov zoo kawg ntawm nws cov molecules yog attracted rau qhov tsis zoo kawg ntawm dej molecules, thiab vice versa. ' Lub zog tawg ntawm cov dej yog qhov tseem ceeb heev rau lub neej Lub ntiaj teb.

Xav txog qhov no, polarity cuam tshuam li cas rau txoj kev peb sib xyaw cov khoom sib xyaw?

Polar tshuaj yog attracted rau polar tshuaj yog li, yog tias koj mix a polar tshuaj thiab tsis yog- polar tshuaj , nws yog feem ntau yuav hais tias cov molecules ntawm cov polar tshuaj yuav kev sib raug zoo nrog lwm tus tsis yog polar molecule (nco tias a polar molecule muaj ib feem tsis zoo thiab ib nrab zoo kawg

Kuj Paub, 3 yam tseem ceeb tshaj plaws ntawm dej yog dab tsi? Lub ntsiab cov khoom ntawm dej yog nws polarity, cohesion, adhesion, nto nro, siab tshwj xeeb kub, thiab evaporative txias. A dej molecule raug them me ntsis ntawm ob qhov kawg. Qhov no yog vim muaj oxygen ntau electronegative tshaj hydrogen.

Qhov thib ob, vim li cas dej polarity tseem ceeb?

Polarity tsuas yog txhais tau hais tias cov molecule muaj ob qho tib si zoo thiab tsis zoo them kawg. 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.

Polarity txhais li cas?

Hauv chemistry, polarity hais txog txoj kev uas atoms sib raug zoo nrog ib leeg. Thaum cov atoms tuaj ua ke hauv cov tshuaj sib txuas, lawv sib koom electrons. A polar molecule tshwm sim thaum ib qho ntawm cov atoms ua kom muaj zog txaus nyiam ntawm cov electrons hauv daim ntawv cog lus.
