Cov no zog tuaj yeem muab faib ua 2 yam : Intramolecular zog : Intramolecular zog ntawm attraction yog cov zog ntawm attraction uas khaws ib qho molecule ua ke. Intermolecular zog : Intermolecular zog yog zog ntawm attraction los yog repulsion uas ua ntawm cov nyob sib ze hais (atoms, molecules los yog ions).
Hais txog qhov no, ob hom kev quab yuam yog dab tsi?
Muaj peb hom ntawm txaus nyiam zog . Cov gravitational attraction nyob ntawm pawg, hluav taws xob kev nyiam nyob ntawm tus nqi sib txawv, thiab sib nqus kev nyiam nyob ntawm cov dej ntws mus rau tib txoj kev.
Kuj Paub, ob lub zog yog dab tsi? Muaj ob hom ntawm zog : Hu rau zog : Cov khoom nyob rau hauv kev sib cuag nrog ib leeg thiab exert zog ntawm ib leeg. Tsis sib cuag (field) zog : Cov khoom tsis nyob rau hauv kev sib cuag nrog ib leeg thiab exert zog ntawm ib leeg.
Tsis tas li ntawd, dab tsi yog lub zog ntawm attraction?
Attractive intermolecular rog yog categorized rau hauv hom hauv qab no:
- Hydrogen bonding.
- Ionic kev sib txuas.
- Ion-induced dipole zog.
- Ion-dipole zog.
- van der Waals rog – Keesom force, Debye force, thiab London dispersion force.
Dab tsi yog quab yuam ntawm attraction hauv chemistry?
Intermolecular zog yog cov zog ntawm attraction los yog repulsion uas ua ntawm cov nyob sib ze hais (atoms, molecules, los yog ions). Cov no zog tsis muaj zog piv rau cov intramolecular zog , xws li covalent lossis ionic bonds ntawm atoms hauv ib lub molecule.

Dab tsi yog qhov quab yuam ntawm ib qho khoom hauv qhov zoo li qub lossis dynamic equilibrium?
Thaum lub net quab yuam ntawm ib yam khoom sib npaug rau zerothen cov khoom no yog nyob rau ntawm so (staticequilibrium) los yog txav ntawm qhov nrawm nrawm (dynamicequilibrium)
Vim li cas kev sib txhuam quab yuam tsis yog kev ruaj ntseg?
Lub zog yog hais tias tsis yog-conservative thaum ua hauj lwm tawm tsam nws tsis tseg los ntawm lub cev uas yog txav los ntawm lub zog. Ib qho piv txwv zoo ntawm hom kev quab yuam tsis yog kev sib txhuam. Thaum lub cev txav tawm tsam kev sib txhuam, kev ua haujlwm yuav tsum tau kov yeej kev sib txhuam. Kev ua haujlwm yog lub zog thiab yog li nws tsis tuaj yeem poob
Hom quab yuam yog magnetic teb?
Sib nqus rog yog tsim los ntawm kev txav ntawm cov khoom siv hluav taws xob xws li electrons, uas qhia txog kev sib raug zoo ntawm cov hlau nplaum thiab hluav taws xob. Daim ntawv paub zoo tshaj plaws ntawm cov hlau nplaum yog qhov txaus nyiam lossis kev quab yuam uas ua rau cov khoom sib nqus xws li hlau
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Qhov unit ntawm electromotive quab yuam yog dab tsi?
Txawm hais tias nws lub npe, lub zog hluav taws xob tsis yog lub zog tiag tiag. Nws yog feem ntau ntsuas nyob rau hauv units ntawm volts, sib npaug hauv meter-kilogram-thib system rau ib joule ib coulomb ntawm hluav taws xob nqi
