Qee lub tebchaw, xws li dej, yog tsis tshua muaj volatile; Feem ntau qhov no yog vim muaj cov tshuaj lom neeg muaj zog ntawm cov molecules-feem ntau yog cov hydrogen bonds-uas tawm tsam cov nyiam ntawm cov molecules rau nkag mus rau hauv lub xeev gaseous.
Puas yog dej yog qhov hnyav hnyav?
Ib qho piv txwv zoo ntawm cov tshuaj tsis hloov pauv yog cov dej qab zib. Raws li tus nqi ntawm cov piam thaj hauv cov tshuaj nce ntxiv, lub boiling point kuj nce, nrog ib tug txo nyob rau hauv vapor siab. Piv txwv li, ib qho tshuaj volatile yog ib qho uas evaporates yooj yim. … Solutes + Solvents=Solutions, and dej is the universal solvent
Puas yog dej yog cov khoom tsis haum?
Zuag qhia tag nrho, dej yog lub ntsiab tsis hloov pauv thaum lub sijhawm tawg.
Puas yog dej tsis muaj tshuaj lom?
Lub volatility ntawm ib yam khoom yog cuam tshuam los ntawm lub zog ntawm intermolecular rog. Piv txwv li, dej tsis tuaj yeem hloov pauv ntawm chav tsev kub thiab yuav tsum tau ua kom sov kom evaporate. Qhov no yog vim hydrogen bonding ntawm cov molecules.
Yuav ua li cas yog tsis-volatile?
Glycerin (C3H8O3)yog cov kua uas tsis muaj hluav taws xob. Qab Zib (sucrose) thiab ntsev (sodium chloride) yog cov khoom tsis muaj zog. Tej zaum nws yuav yooj yim dua los xav txog cov khoom uas tsis muaj hluav taws xob yog tias koj xav txog cov khoom ntawm cov khoom uas tsis hloov pauv. Piv txwv suav nrog cawv, mercury, roj av, thiab naj hoom.

Puas yog cov dej qab ntsev lossis cov ntses dej ntsev?
Nws yog ib qho chaw nyob hauv ntug dej, cov ntses uas siv nws lub neej feem ntau hauv dej ntsev tab sis tsiv mus rau cov pas dej tshiab thiab cov kwj deg hauv lub caij nplooj ntoo hlav kom loj hlob. Txawm li cas los xij, smelt yog hom hloov tau yooj yim, thiab cov neeg nyob hauv av tau tsim lawv tus kheej los ntawm Maine mus rau Great Lakes thiab sab qab teb Canada .
Puas yog nthwv dej hauv dej hla lossis ntev?
Txhua hom hluav taws xob nthwv dej taug kev ntawm tib lub nrawm los ntawm lub tshuab nqus tsev, xws li los ntawm qhov chaw. Dej nthwv dej thiab S nthwv dej kuj yog hla nthwv dej . Puas yog nthwv dej hauv dej hiav txwv hla lossis ntev?
Puas yog cov dej ntshiab lossis dej ntsev?
Ib lub strait yog ib lub cev nqaim ntawm dej uas txuas ob lub cev loj ntawm dej … Hauv ob peb txhiab xyoo, Strait of Gibr altar yuav yog Isthmus ntawm Gibr altar, thiab Mediterranean yuav yog ib qho loj, ntsev, dej hiav txwv. Yog tias pob txha hauv isthmus yog tsim los ntawm tib neeg kev ua haujlwm, cov straits feem ntau hu ua kwj dej .
Puas yog cichlids dej tshiab lossis dej ntsev?
African cichlids muaj yeeb yuj, muag heev freshwater ntses uas yog qhov sib ntxiv rau cov thoob dej yug ntses. Lub npe cichlid tiag tiag yog hais txog tag nrho tsev neeg ntawm ntses, thiab muaj ntau hom cichlid muaj ntau yam xim, qhov ntau thiab tsawg thiab lub cev hom .
Puas yog txoj kev hauv dej hiav txwv tshiab lossis dej ntsev?
Txoj Kev Intracoastal Waterway yog ua los ntawm natural inlets, dej ntsev, baysthiab cov kwj dej uas tib neeg tsim. Txoj kev dej no tseem ceeb heev vim nws yog ib txoj hauv kev uas cov nkoj tuaj yeem taug kev ntawm Atlantic thiab Gulf ntug dej hiav txwv thaum zam kev phom sij ntawm dej hiav txwv qhib .
