Raws li zog yog kis los ntawm ib yam khoom mus rau lwm tus, lub zog ntawm txhua yam khoom raug hloov, tab sis tsis yog nws tshuaj pleev. Dissolving ib yam nyob rau hauv lwm yam kuj yog ib tug hloov lub cev.
Hais txog qhov no, lub zog puas tuaj yeem tso tawm thaum muaj teeb meem hloov pauv?
Teb thiab piav qhia: Yog, zog tau ua tso tawm thaum muaj teeb meem hloov . Hauv lub cev kev hloov , zoo li theem kev hloov , zog yog tso tawm thaum hloov ntawm qhov siab dua zog
Ib yam li ntawd, puas yog decomposing lub cev lossis tshuaj hloov pauv? Decomposition , qhov sib txawv ntawm kev sib xyaw ua ke, suav nrog kev tawg ntawm ib yam khoom rau hauv ob lossis ntau yam sib txawv. Cov cim ntawm tshuaj hloov suav nrog kev hloov nyob rau hauv cov xim, kub, zus tau tej cov teeb, kev hloov nyob rau hauv tsw, thiab tsim ntawm gases.
Ib yam li ntawd, tej zaum koj yuav nug, yuav ua li cas rau ib yam khoom thaum hloov lub cev?
Kev hloov ntawm lub cev tshwm sim thaum khoom los yog tshuaj undergo ib hloov uas tsis hloov lawv cov tshuaj muaj pes tsawg leeg. Qhov no sib txawv nrog lub tswvyim ntawm chemical hloov uas muaj pes tsawg leeg ntawm a tshuaj hloov los yog ib los yog ntau tshaj tshuaj ua ke los yog tawg los tsim tshiab tshuaj.
Puas yog lub zog ntxiv los yog tshem tawm hauv cov hws?
Gas mus rau lub Kua Ib Dua Xav txog qhov piv txwv ntawm txoj kev hauv tsev, tab sis cov neeg coob coob tsiv sai dua. Lub ntsiab lus ntawm qhov khoom mus txog condensation hu ua nws condensation taw tes. Rau qhov ceev ceev molecules nyob rau hauv ib tug roj kom qeeb lawv muaj zog tshem tawm . Condensation yog evaporation nyob rau hauv thim rov qab.

Puas yog kev lim tawm lub cev lossis tshuaj hloov pauv?
Cov khoom sib xyaw tuaj yeem sib cais los ntawm kev hloov lub cev, suav nrog cov txheej txheem xws li chromatography, distillation, evaporation, thiab pom. Lub cev hloov pauv tsis hloov qhov xwm txheej ntawm cov khoom, lawv tsuas hloov daim ntawv. Cov khoom ntshiab, xws li cov khoom sib txuas, tuaj yeem sib cais los ntawm kev hloov tshuaj
Puas yog hluav taws kub nyhiab yog qhov hloov pauv ntawm lub cev lossis tshuaj lom neeg?
Thaum cov roj hlawv nws feem ntau ua ke nrog oxygen kom muab cov pa roj carbon dioxide, dej thiab lwm yam nrog rau kev tso tawm ntawm lub zog. Los ntawm kev txhais, nws yog kev hloov tshuaj
Thaum ib qho kev sib cais ua rau muaj kev hloov pauv hloov pauv ntawm lub ntiaj teb nce ntxiv?
Txij li thaum lub kaw lus raug cais tawm, tsis muaj cua sov tuaj yeem khiav tawm (tus txheej txheem yog li adiabatic), yog li thaum lub zog ntws tawm hauv lub cev, qhov entropy ntawm qhov system nce, piv txwv li Δ Ssys> 0. Yog li ntawd, lub entropy ntawm lub system yuav tsum tau nce rau ib tug spontaneous txheej txheem nyob rau hauv no cais system
Lub zog siv hluav taws xob txuag tau li cas thaum hloov pauv lossis hloov pauv?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias rau txhua qhov system, lub zog tsis tuaj yeem tsim lossis rhuav tshem; nws tsuas tuaj yeem hloov ntawm ib daim ntawv mus rau lwm qhov lossis hloov ntawm ib yam khoom mus rau lwm qhov. Mechanical zog los ntawm ob hom: lub zog muaj peev xwm, uas yog khaws cia lub zog, thiab lub zog kinetic, uas yog lub zog ntawm kev txav
Puas muaj kev hloov pauv ntawm lub cev lossis tshuaj lom neeg thaum muaj suab thaj yaj hauv dej?
Dissolving qab zib hauv dej yog ib qho piv txwv ntawm kev hloov lub cev. Nov yog vim li cas: Kev hloov tshuaj lom neeg tsim cov khoom siv tshuaj tshiab. Txhawm rau kom qab zib hauv dej los ua cov tshuaj hloov pauv, ib yam tshiab yuav tsum tau ua. Yog tias koj evaporate cov dej los ntawm cov kua qab zib-dej, koj nyob nraum nrog qab zib
