Tshuaj muaj zog yog ib daim ntawv ntawm zog . Nws yog zog uas yog khaws cia rau hauv daim ntawv cog lus ntawm atoms thiab molecules. Atoms yog lub hauv paus tsev thaiv ntawm txhua yam teeb meem. Lawv tuaj yeem ua ke nrog lwm cov atoms los tsim cov molecules. Tshuaj muaj zog yog dab tsi tuav cov atoms hauv ib lub molecule ua ke.
Tsis tas li ntawd, dab tsi yog ib qho yooj yim txhais ntawm tshuaj zog?
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 chemical zog nyob rau hauv ib lub roj teeb kuj muab hluav taws xob los ntawm txhais tau tias ntawm electrolysis.
Kuj Paub, dab tsi yog 5 yam piv txwv ntawm lub zog tshuaj? Piv txwv ntawm cov teeb meem uas muaj tshuaj lom neeg muaj xws li:
- Coal: Cov tshuaj tiv thaiv combustion converts chemical zog rau hauv lub teeb thiab kub.
- Ntoo: Cov tshuaj tiv thaiv combustion converts chemical zog rau hauv lub teeb thiab kub.
- Petroleum: tuaj yeem hlawv kom tso lub teeb thiab cua sov los yog hloov mus rau lwm hom tshuaj siv zog, xws li roj av.
Yog li ntawd, dab tsi yog lub ntsiab lus ntawm chemical zog thiab piv txwv?
Tshuaj muaj zog yog lub peev xwm ntawm a tshuaj cov ntaub ntawv rau undergo a tshuaj tshuaj tiv thaiv hloov mus rau lwm yam khoom. Piv txwv suav nrog roj teeb, khoom noj, roj av, thiab lwm yam.
Hom hluav taws xob twg khaws cia hauv cov tshuaj?
muaj peev xwm zog

Lub zog hauv science rau Qib 5 yog dab tsi?
Lub zog yog lub peev xwm ua haujlwm. Koj xav tau lub zog los yuam kom ib qho khoom txav mus. Koj xav tau lub zog los hloov qhov teeb meem. Cov cua tshuab, lub hnub sov so thiab nplooj poob yog tag nrho cov piv txwv ntawm lub zog siv
Qib kev ntsuas rau qib kev zoo siab yog dab tsi?
kev cai Hais txog qhov no, qhov ntsuas kev zoo siab yog dab tsi? Yooj yim muab tso, kev noj qab nyob zoo yog txhais raws li koj qhov kev ntsuam xyuas ntawm a) koj tus kheej lub neej, thiab b) koj lub siab xav thiab kev xav-li no daim ntawv lo "
Hom kab mob twg siv lub zog los ntawm lub hnub ci thiab hloov mus rau chemical zog?
Photosynthesis yog cov txheej txheem los ntawm cov kab mob uas muaj cov xim chlorophyll hloov lub teeb lub zog rau hauv cov tshuaj siv zog uas tuaj yeem khaws cia rau hauv cov khoom sib txuas ntawm cov organic molecules (piv txwv li, suab thaj)
Nws hu ua li cas thaum lub teeb lub zog hloov mus rau chemical zog?
Photosynthesis. Photosynthesis yog cov txheej txheem los ntawm cov kab mob uas muaj cov xim chlorophyll hloov lub teeb lub zog rau hauv cov tshuaj siv zog uas tuaj yeem khaws cia rau hauv cov khoom sib txuas ntawm cov organic molecules (piv txwv li, suab thaj)
Puas yog chemical zog yog ib daim ntawv ntawm lub zog muaj peev xwm?
Tshuaj muaj peev xwm muaj peev xwm yog ib daim ntawv ntawm lub zog muaj peev xwm cuam tshuam nrog kev teeb tsa ntawm atoms lossis molecules. Qhov kev npaj no yuav yog qhov tshwm sim ntawm cov khoom siv tshuaj lom neeg hauv ib lub molecule lossis lwm yam. Chemical zog ntawm ib yam tshuaj muaj peev xwm hloov mus rau lwm yam ntaub ntawv ntawm lub zog los ntawm ib tug tshuaj tiv thaiv
