Muaj cov cim qhia uas a tshuaj tiv thaiv tshwm sim. npuas daim ntawv , ib tug roj yog muab tawm, thiab lub beaker tau kub heev. Lub cim tseem ceeb tshaj plaws uas a tshuaj tiv thaiv tshwm sim yog cov tsim ntawm cov khoom tshiab . Cov cov khoom tshiab yog cov pa roj carbon, cov khoom dub nkig, thiab dej vapor, roj tsis muaj xim.
Yog li ntawd, dab tsi yog ib yam khoom tshiab tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj?
A tshuaj tiv thaiv yog cov txheej txheem uas atoms tam sim no nyob rau hauv pib tshuaj rearrange muab tshiab tshuaj kev sib xyaw ua ke muaj nyob hauv cov khoom tsim los ntawm tshuaj tiv thaiv . Cov no pib tshuaj ntawm a tshuaj tiv thaiv hu ua reactants, thiab cov cov khoom tshiab qhov tshwm sim yog hu ua cov khoom.
Ib qho piv txwv ntawm cov khoom tshiab raug tsim yog dab tsi? Kev hloov tshuaj lom neeg ( tshuaj tiv thaiv ) yog ib qho kev hloov ntawm cov ntaub ntawv mus rau lwm yam, cov khoom tshiab nrog cov khoom sib txawv, thiab ib qho los yog cov khoom tshiab raug tsim. Kev kub hnyiab ntawm ntoo yog kev hloov tshuaj raws li cov khoom tshiab uas tsis tuaj yeem hloov rov qab (xws li carbon dioxide) tsim.
Ib yam li ib tug yuav nug, koj tuaj yeem qhia tau li cas yog tias muaj cov khoom tshiab?
Yog; cov khoom tshiab tsim , raws li pov thawj los ntawm cov xim hloov thiab npuas. Qee cov cim qhia txog kev hloov tshuaj lom neeg yog kev hloov xim thiab cov tsim ntawm npuas. Tsib yam kev hloov tshuaj lom neeg: xim chage, tsim ntawm ib tug dej nag, tsim ntawm cov pa roj, tsw hloov, kub hloov.
Cov khoom tshiab twg koj tuaj yeem pom thaum tsim cov khoom tshiab?
Qhov kev hloov ntawm qhov kub thiab txias qhia tau tias muaj kev hloov pauv ntawm lub zog. Hloov hauv Cov khoom Hloov hauv khoom tshwm sim thaum cov tshuaj tshiab . Piv txwv li, kev tsim cov roj av, tsim ntawm cov nag lossis daus, thiab kev hloov xim yog tag nrho cov pov thawj tias muaj tshuaj lom neeg tshwm sim.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Yuav ua li cas koj thiaj paub tias ib yam dab tsi yog ib yam khoom dawb huv los yog sib tov?
1. Cov tshuaj dawb huv tsis tuaj yeem muab cais ua lwm yam teeb meem, thaum sib xyaw yog sib xyaw ntawm ob lossis ntau dua cov khoom ntshiab. 2. Cov khoom ntshiab muaj lub cev tsis tu ncua thiab tshuaj lom neeg, thaum cov khoom sib xyaw muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg (piv txwv li, qhov kub thiab txias)
Yuav ua li cas koj thiaj paub yog hais tias ib tug function tsis yog ib tug function?
Kev txiav txim siab seb qhov kev sib raug zoo yog qhov ua haujlwm ntawm daim duab yog qhov yooj yim los ntawm kev siv cov kab ntsug. Yog tias txoj kab ntsug hla qhov kev sib raug zoo ntawm daim duab ib zaug hauv txhua qhov chaw, qhov kev sib raug zoo yog qhov ua haujlwm. Txawm li cas los xij, yog tias txoj kab ntsug hla qhov kev sib raug ntau dua ib zaug, qhov kev sib raug zoo tsis muaj nuj nqi
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
Yuav ua li cas yog hais tias cov tshuaj sib npaug tsis sib npaug?
Yog tias qhov sib npaug ntawm cov tshuaj tsis sib npaug ces nws ua txhaum txoj cai lij choj ntawm Kev Tiv Thaiv MASS uas tau muab los ntawm Antoine Lavoiser, nws hais tias tus naj npawb ntawm cov atoms nyob rau sab reactant yuav sib npaug ntawm cov atoms nyob rau hauv cov khoom ntawm tib lub ntsiab los yog peb. tuaj yeem hais tias atoms tsis tuaj yeem rhuav tshem los yog ua tau
