Koj lub cev siv chemical zog txhua hnub los ua haujlwm txhua hnub. Cov zaub mov muaj calories thiab thaum koj zom cov zaub mov, cov zog tso tawm. Cov molecules nyob rau hauv cov zaub mov yog tawg mus rau hauv me me pieces. Raws li cov kev sib txuas ntawm cov atoms tawg los yog loosen, oxidation tshwm sim.
Xav txog qhov no, tib neeg siv tshuaj zog li cas?
Cov zaub mov peb noj muaj khaws cia chemical zog . Raws li kev sib txuas ntawm cov atoms hauv cov zaub mov loosen lossis tawg, a tshuaj cov tshuaj tiv thaiv tshwm sim, thiab cov tshuaj tshiab raug tsim. Cov zog ua los ntawm cov tshuaj tiv thaiv no ua rau peb sov, pab peb txav, thiab tso cai rau peb loj hlob.
piv txwv ntawm chemical zog yog dab tsi? Roj teeb, biomass, roj av, natural gas, thiab thee yog cov piv txwv ntawm cov khoom siv hluav taws xob khaws cia. Feem ntau, thaum lub zog tshuaj raug tso tawm los ntawm ib yam khoom, cov khoom ntawd hloov mus rau hauv cov khoom tshiab.
Ib yam li ntawd, tej zaum koj yuav nug, lub zog tshuaj lom neeg tsim li cas?
Tshuaj muaj zog , Zog khaws cia rau hauv daim ntawv cog lus ntawm tshuaj tshuaj sib xyaw. Tshuaj muaj zog tej zaum yuav raug tso tawm thaum lub sij hawm ib tshuaj tshuaj tiv thaiv, feem ntau nyob rau hauv daim ntawv ntawm tshav kub; Cov tshuaj tiv thaiv zoo li no hu ua exothermic. Cov tshuaj tiv thaiv uas yuav tsum tau ua kom muaj cua sov los ua haujlwm tuaj yeem khaws qee qhov ntawd zog raws li chemical zog hauv daim ntawv cog lus tshiab.
Vim li cas chemical zog tseem ceeb?
Peb lub cev siv chemical zog ua haujlwm txhua hnub. Thaum lub sij hawm exothermic tshuaj tshuaj tiv thaiv, chemical zog nyob rau hauv daim ntawv ntawm tshav kub yog tso tawm. Nroj tsuag ua a tshuaj tshuaj tiv thaiv txhua zaus lawv siv hnub ci los ua lawv cov zaub mov thaum lub sijhawm photosynthesis.

Yuav ua li cas rau lub zog nyob rau hauv ib tug exothermic tshuaj tiv thaiv?
Cov tshuaj tiv thaiv exothermic tshwm sim thaum lub zog siv los rhuav tshem cov ntawv cog lus hauv cov reactants (cov khoom pib) tsawg dua lub zog tso tawm thaum cov nyiaj tshiab tau tsim nyob rau hauv cov khoom (cov khoom koj xaus nrog). Combustion yog ib qho piv txwv ntawm cov tshuaj tiv thaiv exothermic - koj tuaj yeem hnov cov cua sov uas tau muab tawm yog tias koj nyob ze dhau
Yuav ua li cas rau lub zog nyob rau hauv ib tug endothermic cov tshuaj tiv thaiv?
Cov tshuaj tiv thaiv kab mob endothermic tshwm sim thaum lub zog siv los rhuav tshem cov ntawv cog lus hauv cov reactants ntau dua li lub zog muab tawm thaum cov ntawv cog lus tsim hauv cov khoom. Qhov no txhais tau hais tias tag nrho cov tshuaj tiv thaiv yuav siv lub zog, yog li ntawd muaj qhov kub thiab txias hauv ib puag ncig
Yuav ua li cas yog lub cev nyob rau hauv static equilibrium thaum sib txawv zog ua rau nws?
Ob qho xwm txheej ntawm kev sib npaug yuav tsum tau ua kom ntseeg tau tias qhov khoom nyob hauv qhov sib npaug zoo li qub. Tsis tsuas yog yuav tsum tau tag nrho cov quab yuam ua raws li cov khoom yuav xoom, tab sis cov sum ntawm tag nrho cov torques ua raws li cov khoom yuav tsum yog xoom
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
Dab tsi organelle hloov cov tshuaj zog uas khaws cia hauv cov zaub mov rau hauv lub zog siv tau?
Mitochondria yog cov organelles ua haujlwm uas ua rau lub cell muaj zog. Hauv cov nroj tsuag ntawm tes, chloroplast ua rau cov suab thaj thaum lub sij hawm cov txheej txheem ntawm photosynthesis hloov lub teeb lub zog mus rau hauv tshuaj lub zog khaws cia hauv qabzib
