Cov piv txwv zoo ntawm lub cev muaj xws li qhov ntom ntom, xim, hardness, melting thiab boiling point, thiab hluav taws xob conductivity. … Piv txwv ntawm cov khoom muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion.
Vim li cas qhov ntom ntom yog cov khoom siv tshuaj?
Txoj Kev Ntsig yog suav tias yog lub cev khoomas; Qhov ntom yog qhov piv ntawm qhov hnyav rau qhov ntim ntawm cov khoom. … Qhov ntom ntawm ib yam khoom tseem nyob tas li thiab tsis nyob ntawm seb muaj pes tsawg ntawm cov khoom. Tsis tas li ntawd, cov tshuaj tsis tas yuav tsum muaj cov tshuaj tiv thaiv rau kev txheeb xyuas nws qhov ntom.
Puas yog qhov ntom ntom ntawm lub cev lossis tshuaj lom neeg?
A lub cev khoom yog ib yam ntawm cov teeb meem uas tsis cuam tshuam nrog kev hloov pauv hauv nws cov tshuaj muaj pes tsawg leeg. Cov piv txwv paub ntawm lub cev muaj xws li qhov ntom ntom, xim, hardness, melting thiab boiling point, thiab hluav taws xob conductivity.
Puas yog cov khoom muaj tshuaj lom neeg?
Cov khoom siv tshuaj yog cov uas tuaj yeem tsim los ntawm kev ua cov tshuaj tiv thaiv (kub ntawm combustion, flash point, enthalpies ntawm kev tsim, thiab lwm yam). Qhov ntom tuaj yeem tsim tau yooj yim los ntawm kev txiav txim siab qhov loj thiab ntim ntawm cov khoom, tsis muaj cov tshuaj tiv thaiv, yog li nws yog lub cev khoom
Puas yog qhov ntom ntom yog cov khoom siv tshuaj lom neeg?
Cov khoom siv dav dav xws li xim, ntom ntom, tawv, yog cov piv txwv ntawm lub cev muaj zogCov khoom uas piav qhia tias cov tshuaj hloov pauv mus rau hauv cov khoom sib txawv kiag li hu ua cov khoom siv tshuaj. Flammability thiab corrosion / oxidation kuj yog cov piv txwv ntawm cov khoom siv tshuaj.

Puas yog ib qho tseem ceeb ntawm cov tshuaj lom neeg lom neeg ntawm thiols?
Dab tsi ntawm cov hauv qab no yog qhov tseem ceeb ntawm cov tshuaj lom neeg lom neeg ntawm thiols? kev oxidation ntawm ob thiols los ua ib tug disulfide . Yam thiols yog dab tsi? 1 BIOLOGICAL THIOLS Thiols xa mus rau chav kawm ntawm cov organic sulfur derivatives uas yog tus cwj pwm los ntawm qhov muaj sulfhydryl residues (–SH) ntawm lawv qhov chaw nquagTshuaj, thiols yog mercaptans (C-SH) thiab biological mercaptans feem ntau hu ua biological thiols lossis biothio
Kev kwv yees qhov ntom ntom ntom?
Hauv kev txheeb cais, cov tshuaj kwv yees ntom ntom yog qhov tsis yog-ntsuas txoj kev ua haujlwm ntawm kev sib txawv. Kernel Qhov Kev kwv yees yog ib cov teeb meem uas du cov teeb meem uas tau ua, raws li cov ntaub ntawv finite. Koj suav li cas kernel ntom?
Puas yog qhov ntom ntom yog cov cuab yeej macroscopic?
“ Cov khoom muaj teeb meem hauv ntauyog hu ua macroscopic properties. … Cov khoom muaj feem xyuam nrog lub tshuab macroscopic suav nrog - siab, kub, ntom, ntim, viscosity, tsis kam, qhov nro ntawm cov kua thiab lwm yam . piv txwv ntawm cov khoom macroscopic yog dab tsi?
Nyob hauv quantum mechanical qauv ib qhov chaw ntom ntom nyob qhov twg?
Ib huab cua hluav taws xob muaj qhov sib txawv: qhov ntom ntom qhov twg cov hluav taws xob feem ntau yuav yogthiab qhov ntom ntom uas cov hluav taws xob tsawg tsawg yuav yog (Daim duab 1) . Electrons nyob qhov twg hauv quantum mechanical qauv?
Puas yog cov pa roj muaj qhov ntom ntom?
Gas ntom. Ib qho tseem ceeb ntawm cov khoom siv roj yog nws qhov ntom ntom. … Tab sis rau cov pa roj, qhov ceev tuaj yeem sib txawv ntawm ntau yam vim tias cov molecules dawb txav. Huab cua ntawm lub ntiaj teb muaj qhov sib txawv heev dua li huab cua 50 mais saum lub ntiaj teb .
