Sublimation yog kev hloov ntawm ib yam khoom ncaj qha los ntawm lub khov kho mus rau gas xeev, tsis dhau lub xeev ua kua. Cov txheej txheem thim rov qab ntawm sublimation yog deposition lossis desublimation, nyob rau hauv uas ib yam khoom kis ncaj qha los ntawm a gas rau a khov kho theem.
Ua li no, nws hu ua dab tsi thaum cov khoom hloov pauv mus rau cov pa roj?
Thaum a khoom hloov hauv a gas , yog hu ua sublimation. Thaum a gas hloov rau hauv cov kua, nws yog hu ua condensation. Thaum ua kua kev hloov hauv a khov kho , yog hu ua solidification. Thaum a gas pauv hauv a khov kho , yog hu ua tso nyiaj.
Tsis tas li ntawd, puas tuaj yeem hloov pauv ncaj qha mus rau cov pa roj? Cov txheej txheem uas a khoom hloov ncaj qha mus rau ib qho roj hu ua sublimation. Nws tshwm sim thaum cov particles ntawm a khov kho nqus zog txaus kom kov yeej lub zog ntawm kev nyiam ntawm lawv. Dej khov qhuav ( khov kho carbon dioxide, CO2) yog ib qho piv txwv ntawm a khov kho uas undergo sublimation.
Qhov thib ob, cov kua ua kua thiab roj yog dab tsi?
Roj , kua thiab cov khoom khib nyiab tag nrho yog tsim los ntawm atoms, molecules, thiab / lossis ions, tab sis cov cwj pwm ntawm cov khoom no txawv nyob rau hauv peb theem. gas zoo sib cais yam tsis muaj kev npaj. ua kua nyob ze ua ke nrog tsis muaj kev npaj. khov kho yog nruj nreem ntim, feem ntau nyob rau hauv ib tug tsis tu ncua qauv.
Dab tsi yog sublimation muab peb piv txwv?
Sublimation yog hom kev hloov pauv, lossis hloov pauv hauv lub xeev ntawm cov teeb meem, ib yam li melting, khov, thiab evaporation. Los ntawm sublimation , ib yam khoom hloov ntawm cov khoom mus rau ib qho roj yam tsis tau dhau los ntawm cov kua theem. Cov dej khov qhuav, cov khoom CO2, muab qhov sib txawv piv txwv ntawm sublimation.

Dab tsi yog thawj kauj ruam ntawm kev tsim ib qho perpendicular los ntawm ib qho taw tes mus rau kab?
Txuas tus taw tes rau qhov taw tes uas cov arcs sib tshuam. Siv ib tug straightedge los xyuas kom meej cov kab yog ncaj. Txoj kab koj kos yog perpendicular rau thawj kab, los ntawm qhov muab taw tes rau ntawm kab
Dab tsi yog 4 yam khoom ntawm ib qho khoom?
Muaj plaub hom crystalline solids: molecular solids, network solids, ionic solids, thiab metallic solids. Ib qho khoom ntawm cov qauv atomic-theem thiab muaj pes tsawg leeg txiav txim siab ntau yam ntawm nws cov khoom macroscopic, xws li, piv txwv li, hluav taws xob thiab hluav taws xob conductivity, ntom, thiab solubility
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Puas yog sodium chloride yog ib qho khoom lossis cov khoom sib xyaw?
Sodium chloride yog ib tug compound nws muaj ob lub ntsiabsodium thiab chlorine lub liab ib yog sodium atom thiab lub greenone yog chlorine
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
