Paub piv txwv ntawm lub cev muaj zog suav nrog ceev, xim, hardness, melting thiab boiling cov ntsiab lus, thiab hluav taws xob conductivity. Peb tuaj yeem soj ntsuam qee qhov lub cev muaj zog , xws li ceev thiab xim, tsis hloov cov lub cev lub xeev ntawm qhov teeb meem pom.
Ib yam li ntawd, tib neeg nug, dab tsi yog lub cev khoom thiab piv txwv?
Piv txwv ntawm lub cev muaj zog yog: xim, tsis hnov tsw, khov point, boiling point, melting point, infrared spectrum, attraction (paramagnetic) los yog repulsion (diamagnetic) rau hlau nplaum, opacity, viscosity thiab ceev. Qhov ntau khoom peb tuaj yeem txheeb xyuas cov khoom, qhov zoo dua peb paub qhov xwm txheej ntawm cov khoom ntawd.
Ib yam li ntawd, leej twg ntawm cov hauv qab no yog lub cev ntawm cov dej? Lub cev muaj zog feem ntau yog cov uas tuaj yeem pom tau siv peb cov kev xav xws li xim, luster, khov taw tes, boiling point, melting point, ntom, hardness thiab tsw. Cov Physical Properties ntawm dej yog raws li nram no: Qhov ceev ntawm dej yog kwv yees li ib gram ib cubic centimeter. Boiling Point: 100 ° C.
Kuj nug tias, khoom vaj khoom tsev txhais li cas?
A khoom ntiag tug yog ib qho vaj tse uas yog ntsuas tau, nws tus nqi piav qhia txog lub xeev ntawm a lub cev qhov system. Cov kev hloov hauv cov lub cev muaj zog ntawm ib qho system tuaj yeem siv los piav txog nws cov kev hloov pauv ntawm lub xeev tam sim no. Lub cev muaj zog feem ntau yog tus yam ntxwv raws li intensive thiab dav khoom.
Qhov twg hauv qab no yog qhov kev txhais zoo tshaj plaws ntawm kev hloov lub cev?
Kev hloov ntawm lub cev yog kev hloov cuam tshuam rau daim ntawv ntawm cov tshuaj, tab sis tsis yog nws cov tshuaj muaj pes tsawg leeg. Piv txwv ntawm lub cev cov khoom muaj xws li melting, hloov mus rau ib qho roj, hloov ntawm lub zog, hloov ntawm durability, kev hloov mus rau crystal daim ntawv, textural hloov , puab, loj, xim, ntim thiab ntom.

Koj yuav daws cov khoom ntiag tug li cas?
Cov Khoom Siv Tus Kheej yog tsim los ntawm ob ntu: Additive Identity thiab Multiplicative Identity. Ntxiv xoom (0) rau tus lej, tus lej yog tus lej ntawd. Muab tus lej los ntawm 1, Cov Khoom yog tus lej ntawd. Faib tus lej los ntawm nws tus kheej, tus Quotient yog 1
Vim li cas huab hwm coj tsis yog yam khoom ntiag tug?
Qhov hnyav, qhov hnyav, ntim, cov duab, qhov ntev / dav, kev ntxhib los mos, thiab qhov kub thiab txias tsis yog cov yam ntxwv ntawm cov khoom thiab tuaj yeem hloov pauv. Cov yam ntxwv ntawm ib yam khoom tsis hloov thaum kub thiab siab nyob li qub
Cov khoom twg yog cov piv txwv ntawm cov khoom siv tshuaj xyuas txhua yam uas siv?
Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2)
Dab tsi yog qhov txawv ntawm inverse thiab cov khoom ntiag tug?
Additive Identity Axiom hais tias tus lej ntxiv rau xoom sib npaug ntawm tus lej ntawd. Lub Multiplicative Identity Axiom hais tias tus lej sib npaug los ntawm 1 yog tus lej ntawd. Additive Inverse Axiom hais tias cov lej ntawm tus lej thiab Additive Inverse ntawm tus lej ntawd yog xoom
Qhov twg hauv qab no yog tag nrho cov khoom ntawm lub cev?
Physical Properties: Lub cev muaj zog tuaj yeem soj ntsuam lossis ntsuas yam tsis tau hloov qhov muaj pes tsawg leeg. Lub cev muaj zog muaj xws li: zoo li, kev ntxhib los mos, xim, tsw, melting point, boiling point, ntom, solubility, polarity, thiab ntau lwm yam
