Intermolecular rog yog electrostatic nyob rau hauv cov xwm thiab suav nrog van der Waals zog thiab hydrogen bonds. Molecules nyob rau hauv cov kua yog tuav mus rau lwm cov molecules los ntawm intermolecular kev sib cuam tshuam, uas tsis muaj zog tshaj qhov intramolecular Kev sib cuam tshuam uas tuav cov atoms ua ke hauv molecules thiab polyatomic ions.
Ib yam li ntawd, tib neeg nug, dab tsi yog lub zog ntawm cov teeb meem?
Intermolecular rog yog lub zog ntawm cov molecules uas txiav txim siab lub cev ntawm lub cev kua thiab cov khoom khib nyiab . 11.2 Vaporization thiab Vapor Pressure- vaporization yog hloov ntawm cov kua rau a gas (vapor), thiab qhov kom muaj nuj nqis ntawm cov cua sov cuam tshuam nrog qhov hloov pauv theem no yog hu ua enthalpy (heat) ntawm vaporization.
Kuj Paub, muaj pes tsawg lub zog intermolecular muaj? plaub
Nyob rau hauv no hais txog, lub xeev ntawm teeb meem twg muaj zog tshaj intermolecular rog?
Ntawm cov xeev ntawm teeb meem Khoom muaj zog tshaj zog ntawm attraction ntawm nws cov molecules. Nyob rau hauv ib qho khoom, molecules tau ntim ua ke, thiab nws khaws nws cov duab. Khoom yog incompressible thiab muaj siab ceev. Nyob rau hauv cov kua, cov intermolecular rog muaj zog txaus kom cov particles khi rau ib leeg.
Dab tsi yog hom kev sib cuam tshuam ntawm cov rog?
Muaj peb hom tseem ceeb ntawm lub zog ntawm intermolecular : London dispersion zog , dipole-dipole kev sib cuam tshuam, thiab ion-dipole kev sib cuam tshuam.

Dab tsi yog qhov txawv ntawm qhov teeb meem thiab lub zog hauv ib qho ecosystem?
Muaj qhov sib txawv tseem ceeb hauv txoj kev lub zog thiab cov teeb meem ntws los ntawm ib qho ecosystem. Cov teeb meem ntws los ntawm ecosystem nyob rau hauv daim ntawv ntawm cov tsis muaj sia nyob cov as-ham tseem ceeb rau cov kab mob nyob. Yog li koj pom, teeb meem yog rov ua dua tshiab hauv ecosystem. Tsis zoo li qhov teeb meem, lub zog tsis rov siv dua los ntawm qhov system
Dab tsi yog qhov txawv ntawm magnification thiab daws teeb meem ntawm ib daim duab nyob rau hauv lub tshuab microscope?
Magnification yog lub peev xwm ua kom cov khoom me me zoo li loj dua, xws li ua kom pom cov kab mob microscopic. Kev daws teeb meem yog qhov muaj peev xwm paub qhov txawv ntawm ob yam khoom ntawm ib leeg. Lub teeb microscopy muaj kev txwv rau ob qho tib si nws qhov kev daws teeb meem thiab nws qhov loj
Dab tsi yog qhov txawv ntawm qhov ntws ntawm cov teeb meem thiab lub zog hauv ib qho ecosystem?
Muaj qhov sib txawv tseem ceeb hauv txoj kev lub zog thiab cov teeb meem ntws los ntawm ib qho ecosystem. Cov teeb meem ntws los ntawm ecosystem hauv daim ntawv ntawm cov khoom noj uas tsis muaj sia nyob uas tseem ceeb rau cov kab mob nyob. Yog li koj pom, teeb meem yog rov siv dua hauv ecosystem. Tsis zoo li qhov teeb meem, lub zog tsis rov siv dua los ntawm qhov system
Dab tsi yog qhov teeb meem ntawm lub teeb nyob rau hauv lub ntuj hmo ntuj hu ua?
Gegenschein, tseem hu ua Counterglow, oval thaj ntawm faint luminosity raws nraim rau lub hnub nyob rau hauv lub hmo ntuj. Lub thaj ntawm lub teeb yog li faint nws tuaj yeem pom tsuas yog thaum tsis muaj lub hli, nyob deb ntawm lub nroog teeb, thiab nrog lub qhov muag yoog rau qhov tsaus ntuj
Lub xeev twg ntawm cov teeb meem twg muaj zog tshaj intermolecular rog ntawm attraction?
Raws li qhov kub thiab txias tseem poob qis, qhov teeb meem tsim muaj zog. Vim tias cov khoom tsis muaj zog kinetic, cov khoom tsis muaj 'lub sij hawm' txav mus los, cov khoom muaj 'lub sij hawm' kom nyiam. Yog li ntawd, cov khib nyiab muaj qhov muaj zog tshaj plaws intramolecular rog (vim lawv muaj qhov muaj zog tshaj plaws)
