Qhov txawv ntawm a cov tshuaj tiv thaiv lub cev thiab a tshuaj tiv thaiv yog muaj pes tsawg leeg. Hauv ib tshuaj tiv thaiv , muaj kev hloov pauv ntawm cov khoom hauv nqe lus nug; hauv a lub cev hloov muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog yooj yim tso saib ntawm ib tug qauv ntawm cov teeb meem yam tsis muaj kev hloov nyob rau hauv muaj pes tsawg leeg.
Ib yam li ntawd, qhov tshuaj tiv thaiv lub cev yog dab tsi?
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, cov txheej txheem twg yog kev hloov tshuaj? Kev hloov tshuaj tshwm sim thaum ib yam khoom sib txuas nrog lwm tus los tsim cov khoom tshiab, hu ua tshuaj synthesis los yog, hloov, tshuaj decomposition rau hauv ob los yog ntau tshaj cov khoom sib txawv. Ib qho piv txwv ntawm a tshuaj hloov yog cov tshuaj tiv thaiv ntawm sodium thiab dej los tsim sodium hydroxide thiab hydrogen.
Tsis tas li ntawd, cov piv txwv ntawm cov tshuaj tiv thaiv lub cev yog dab tsi?
Nco ntsoov, qhov tshwm sim ntawm cov teeb meem hloov pauv hauv lub cev hloov pauv, tab sis nws cov tshuaj lom neeg yog qhov qub
- Crushing ib lub kaus poom.
- Melting ib lub thawv dej khov.
- Boiling dej.
- Sib tov xuab zeb thiab dej.
- Txhaum iav.
- Dissolving qab zib thiab dej.
- Txiav daim ntawv.
- Txiav ntoo.
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv yooj yim txhais?
Tshuaj tiv thaiv , ib txheej txheem uas ib los yog ntau yam tshuaj, cov reactants, yog hloov mus rau ib los yog ntau yam khoom, cov khoom. Cov tshuaj yog ib yam tshuaj cov ntsiab lus los yog compounds. A tshuaj tiv thaiv rearranges lub constituent atoms ntawm cov reactants los tsim cov khoom sib txawv raws li cov khoom.

Dab tsi yog qhov txawv ntawm lub cev thiab tshuaj lom neeg ntawm cov zaub mov?
Minerals raug cais raws li lawv cov tshuaj muaj pes tsawg leeg, uas tau qhia hauv lawv lub cev. Cov qauv no, qhov thib ob hauv cov kab hauv cov ntxhia, piav qhia txog lub cev lub zog uas feem ntau siv los txheeb xyuas cov zaub mov. Cov no muaj xws li xim, crystal form, hardness, ntom, luster, thiab cleavage
Dab tsi yog cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg ntawm dej?
Cov tshuaj lom neeg thiab lub cev tseem ceeb ntawm cov dej yog: dej tsis qab, tsis muaj ntxhiab tsw ntawm tus qauv kub thiab siab. Cov xim ntawm cov dej thiab dej khov yog, intrinsically, ib tug me ntsis xiav hue, txawm tias dej zoo li tsis muaj xim nyob rau hauv me me
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv hauv biology?
Hauv cov ntsiab lus, cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas hloov ib lossis ntau yam rau lwm yam khoom. Cov tshuaj tiv thaiv tshuaj pib nrog reactants thiab hloov mus rau hauv cov khoom
Dab tsi yog qhov sib txawv tseem ceeb ntawm tshuaj lom neeg thiab cov tshuaj tiv thaiv nuclear Lub hlwb?
(1) Cov tshuaj tiv thaiv Nuclear cuam tshuam nrog kev hloov pauv ntawm inan atom lub nucleus, feem ntau tsim cov khoom sib txawv, nrog rau kev tawm ntawm cov hluav taws xob xws liα, β thiab gamma; lwm ray. Cov tshuaj tiv thaiv tshuaj, ntawm qhov tod tes, tsuas yog muaj kev hloov pauv ntawm cov hluav taws xob thiab tsis cuam tshuam nrog kev hloov pauv hauv cov nuclei
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
