Cov tshuaj lom tshwm sim yog cov uas hloov pauv qhov teeb meem tshwm sim, nrog rau cov tsos ntawm qee yam tshuaj thiab kev ploj ntawm lwm tus.
Lawv yuav luag mloog lus tas li tshuaj lom neeg, uas tuaj yeem tshwm sim los yog tshwm sim los ntawm kev sib xyaw cov khoom sib txawv thiab ua rau lawv mus rau qee yam kev mob ntawm kub, los ntawm pH, siab, thiab lwm yam.
Cov tshuaj lom neeg tseem ceeb sib cuam tshuam rau ib yam ntawm cov hauv qab no:
- Synthesis
- Kev lwj
- Ntxiv
- Hloov chaw

Tseem ceeb
Ntau yam tshuaj lom tshwm sim txhawb nqa txoj sia ntawm kev muaj sia nyob, as ua kev zom hauv tib neeg thiab tsiaj txhu, photosynthesis hauv cov nroj tsuag thiab kev ua pa ntawm ob qho tib si.
Lwm qhov txheej txheem tshuaj tseem ceeb heev, tshwj xeeb hauv lub neej ntawm cov kab mob me me, yog fermentation, uas feem ntau yog siv hauv kev tsim khoom noj xws li cheese, yogurts, cawv thiab npias.
Qhov tseeb txhua qhov kev loj hlob thiab kev loj hlob ntawm a ua neej nyob Nws ua raws cov cim qhia tshuaj uas tau tsim hauv nws, qee zaum txhawb los ntawm cov ntsiab lus ntawm ib puag ncig.
Piv txwv ntawm cov tshuaj lom tshwm sim
Muaj ntau qhov xwm txheej ntawm tshuaj lom tshwm sim lossis txheej txheem uas suav nrog lawv nyob ib puag ncig peb, ntawm no yog qee qhov:
- Ntoo lwj
- Ntawv hlawv
- Tshuaj tua kab mob tiv thaiv kab mob
- Mis uas hloov qaub
- Tshuaj tua kab mob nrog cawv
- Siv cov txiv hmab txiv ntoo ntsev los tawm tsam kub cev
- Kub taws
- Ntshav los ntshav
- Cov leeg qaug zog tom qab qoj ib ce
- Kev tuag ntawm kab los ntawm tshuaj tua kab
- Tau txais Roquefort cheese
- Tau txais cider
- Tau txais yogurt
- Kev ua chiv
- Kev ruaj ntseg
- Tau txais bioethanol los ntawm cov suab thaj
- Cov kaus poom o tuaj
- Qe qe
- Rusting ntawm ib tug grate
- Tau txais biodiesel los ntawm xibtes roj

Tshuaj lom tshwm sim hauv kev lag luam
Tsis tas li hauv kev lag luam qee yam tshuaj lom tshwm sim yog qhov tseem ceeb. Rau cov pib, lub combustion ntawm hydrocarbon xws li roj av, diesel lossis kerosene, nws pub cov tshuab uas ua haujlwm suav tsis txheeb.
Ntawm qhov tod tes, kev lag luam hlau, ntawv, yas, cov khoom tsim, pleev xim, tshuaj, khoom ua liaj ua teb, thiab lwm yam, yog ua raws ntau yam tshuaj lom neeg tshwm sim, xws li hlau, cov galvanization, cov hluav taws xob thiab ntau lwm tus.
Nws tseem yog raws li hom kev tshwm sim no tiam tshiab ntawm lub zog tshiab, zoo li biodiesel thiab bioethanol.

Kev hloov pauv ntawm lub zog
Hauv kev tshwm sim tshuaj nws yog ib txwm muaj kev hloov pauv zog. Piv txwv li, tias lub zog tshuaj muaj nyob hauv cov khoom sib txuas ntawm qee yam tshuaj tau hloov pauv mus ua hluav taws xob lossis tso tawm thaum tshav kub kub (qhov no tshwm sim hauv cov xwm txheej exothermic, xws li thaum hydrochloric acid tau sib xyaw nrog zinc), lossis tias lub zog lub zog raug ntes thiab hloov mus ua tshuaj muaj zog.
Qee cov txheej txheem tshuaj xav tau cua sov Yuav kom ua tiav, lawv raug hu ua endothermic, lwm tus xav tau muaj cov catalysts lossis cofactors.
