Cov qhov sib txawv ntawm ib cov tshuaj tiv thaiv lub cev thiab a tshuaj tiv thaiv yog muaj pes tsawg leeg. Hauv ib tshuaj tiv thaiv , muaj a hloov nyob rau hauv muaj pes tsawg leeg ntawm cov tshuaj nyob rau hauv nqe lus nug; hauv a hloov lub cev muaj ib txawv nyob rau hauv tsos, tsis hnov tsw, los yog yooj yim tso saib ntawm ib tug qauv ntawm cov teeb meem tsis muaj a hloov nyob rau hauv muaj pes tsawg leeg.
Tib neeg kuj nug, 3 qhov sib txawv ntawm lub cev thiab tshuaj hloov pauv li cas?
Hauv ib hloov lub cev , cov molecules yog rearranged thaum lawv muaj pes tsawg leeg tseem zoo ib yam. Hauv ib tshuaj hloov , molecular muaj pes tsawg leeg ntawm ib yam khoom kiag li kev hloov thiab ib qho khoom tshiab raug tsim. Ib qho piv txwv ntawm lub cev hloov ua khov ntawm dej, yaj ntawm wax, ua ntawm dej, etc.
Ib sab saum toj no, dab tsi yog qhov tshwm sim ntawm lub cev? A cov tshuaj tiv thaiv lub cev tshwm sim thaum molecules undergo ib molecular rearrangement los tsim ib lub cev hloov. Cov molecules tsis chemically hloov. Raws li kev ceeb toom, molecules yog ob lossis ntau lub atoms txuas los ntawm cov khoom siv tshuaj.
Ib yam li ntawd, koj tuaj yeem nug, qhov txawv ntawm lub cev thiab tshuaj lom neeg hauv chemistry yog dab tsi?
Lub cev muaj zog yog siv los soj ntsuam thiab piav txog qhov teeb meem. Lub cev muaj zog yog siv los soj ntsuam thiab piav txog qhov teeb meem. Cov khoom siv tshuaj tsuas yog pom thaum lub sijhawm a tshuaj cov tshuaj tiv thaiv thiab yog li hloov cov tshuaj tshuaj muaj pes tsawg leeg. Tej zaum qhov zoo tshaj plaws rau paub qhov txawv ntawm ob yog ua piv txwv.
Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab cov txheej txheem tshuaj?
Tshuaj tiv thaiv yog cov txheej txheem “uas “ua rau” tshuaj hloov (transformation) ib tshuaj tshuaj mus rau lwm yam tshiab nkaus ntawm txawv tshuaj tus kheej los yog muaj pes tsawg leeg. Ib” yog tus txheej txheem ( tshuaj tiv thaiv ) uas coj mus rau lwm tus ( hloov ).
