Cov nqi hluav taws xob yog lub cev muaj zog ntawm cov khoom los yog yam khoom ntawd ua rau lawv rau nyiam los yog tawm tsam ib leeg tsis kov. Cov khoom uas muaj cov nqi sib txawv sib nyiam . Cov khoom uas muaj xws li tsub nqi repel ib leeg . Lub zog ntawm attraction los yog repulsion yog hu ua hluav taws xob quab yuam.
Raws li txoj cai, dab tsi ua rau cov khoom nyiam los yog tawm tsam?
Cov nqi hluav taws xob yog lub cev muaj zog ntawm cov khoom los yog khoom. Nws ua rau lawv rau nyiam los yog tawm tsam ib leeg tsis kov.
Tsis tas li ntawd, qhov twg subatomic hais tau attracted rau ib leeg? Daim duab 4.11: Protons thiab electrons sib nyiam vim lawv muaj opposite nqi. Protons raug nqi zoo, thaum electrons raug nqi tsis zoo.
Qhov thib ob, puas tuaj yeem cuam tshuam cov khoom sib txawv?
Qhov sib txawv ntawm cov khoom sib txawv sib txawv , thaum zoo li cov khoom repel ib leeg . Cov hluav taws xob khaws cia rau hauv tus ncig ncig tus nucleus ua tus electromagnetic quab yuam, vim tus nucleus hauv tus nruab nrab ntawm tus atom yog raug nqi zoo thiab attracts tus tsis zoo raug them electrons.
Dab tsi ua rau cov khoom sib txuas ua ke?
Lub ntiajteb txawj nqus yog lub zog uas txhua yam khoom nrog huab hwm coj sib zog rau ib leeg, rub cov khoom los ze zog ua ke . Qhov me me cov khoom uas ua teeb meem , xws li atoms thiab subatomic cov khoom , kuj siv zog rau ib leeg. Cov rog no tsis yog lub ntiajteb txawj nqus, tab sis tshwj xeeb rog uas tsuas yog cov no cov khoom siv.

Dab tsi yog ib qho piv txwv ntawm cov khoom sib txuas ntawm kev sib npaug?
Kev rho tawm (Tsis yog Commutative) Tsis tas li ntawd, kev faib, kev sib xyaw ntawm cov dej num thiab cov lej sib npaug yog ob qho piv txwv zoo uas tsis yog kev sib txuas
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov zoo sib xws ntawm cov khoom thiab cov khoom sib txuas?
Cov ntsiab lus thiab cov tebchaw yog cov tshuaj homogeneous nkaus xwb thiab lawv muaj qhov sib xyaw tas li thoob plaws. Cov ntsiab lus thiab cov tebchaw tsis tuaj yeem sib cais rau hauv lawv cov khoom sib xws los ntawm kev siv lub cev. Cov tshuaj thiab cov khoom sib tov yog tsim los ntawm cov khoom sib txawv lossis cov atom sib txawv
Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Dab tsi ntawm cov khoom sib txuas sib txuas muaj nyob ntawm cov dej molecules?
Piv txwv li, dej molecules yog tuav ua ke los ntawm hydrogen bonds ntawm hydrogen atom ntawm ib lub molecule thiab cov pa atom ntawm lwm tus (daim duab: hydrogen bonds). Hydrogen bonds yog ib qho muaj zog intermolecular quab yuam thiab muaj zog dua lwm cov dipole-dipole rog
