Teeb meem tuaj yeem muab faib ua ob pawg: cov tshuaj ntshiab thiab sib tov . Cov tshuaj ntshiab yog ntxiv rau hauv cov ntsiab lus thiab cov khoom sib txuas. Cov khoom xyaw yog lub cev sib xyaw ua ke uas tuaj yeem sib cais rau hauv lawv cov khoom qub. Cov tshuaj yog tsim los ntawm ib hom atom los yog molecule.
Ntawm no, dab tsi yog qhov teeb meem sib xyaw piv txwv?
Cov khoom xyaw . Ib yam khoom uas muaj tsuas yog ib hom atom lossis ib hom molecule yog cov khoom ntshiab. Feem ntau ntawm teeb meem nyob ib ncig ntawm peb, txawm li cas los xij, muaj sib tov ntawm cov khoom ntshiab. Cua, ntoo, pob zeb thiab av yog piv txwv ntawm tej sib tov.
Tom qab ntawd, lo lus nug yog, qhov teeb meem luv luv yog dab tsi? Hauv science, teeb meem yog lub sij hawm rau txhua yam khoom. Teeb meem yog txhua yam uas muaj huab hwm coj thiab siv qhov chaw. Yam tsawg kawg nkaus, teeb meem yuav tsum muaj tsawg kawg yog ib qho subatomic particle, txawm tias feem ntau teeb meem muaj cov atoms.
Ib tug kuj yuav nug, dab tsi yog sib xyaw hauv science?
A sib tov yog ib yam khoom tsim los ntawm kev sib txuas ob lossis ntau cov khoom sib txawv hauv txoj kev uas tsis muaj tshuaj lom neeg tshwm sim. A sib tov feem ntau tuaj yeem muab cais rov qab rau hauv nws cov khoom qub. Qee qhov piv txwv ntawm sib tov yog cov zaub xam lav, dej ntsev thiab ib lub hnab sib xyaw ntawm M&M cov khoom qab zib.
Dab tsi yog qhov teeb meem thiab nws qhov kev faib tawm?
A teeb meem yog txhua yam uas nyob qhov chaw, muaj huab hwm coj, thiab muaj kev tiv thaiv. Tus nqi ntawm teeb meem muaj nyob rau hauv lub cev yog hu ua nws pawg. Lub cev, teeb meem yog cais nyob rau hauv peb lub xeev: khoom, kua, thiab roj. Tshuaj, teeb meem muab faib ua cov ntshiab thiab impure (sib tov) tshuaj.

Kev sib piv daim duab piv rau Kev Sib Piv Ceev Ceev Tus Nqi Hloov ntawm qhov kev ncua deb Hloov pauv hloov thaum lub cev rov qab mus rau nws qhov chaw pib Yuav tsis xoom Yuav yog xoom Tsiv khoom Ceev ntawm cov khoom txav tsis tuaj yeem tsis zoo. Kev nrawm ntawm cov khoom txav tuaj yeem yog qhov zoo, tsis zoo lossis xoom
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua

Kev sib raug zoo ntawm lub teeb thiab teeb meem yog dab tsi?
Lub teeb thiab teeb meem cuam tshuam rau ib leeg hauv ntau txoj hauv kev. Kev sib cuam tshuam ntawm lub teeb thiab teeb meem txiav txim siab qhov tshwm sim ntawm txhua yam nyob ib puag ncig peb. Lub teeb cuam tshuam nrog cov teeb meem xws li emission thiab nqus. Cov nyhuv photoelectric yog ib qho piv txwv ntawm qhov teeb meem absorbs lub teeb
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
