Tshuaj vs Physical Properties
Txhua yam khoom ntawm cov khoom raug faib ua lub cev thiab tshuaj lom neeg. Peb paub cov tib neeg sib txawv raws li lawv lub cev lub cev xws li qhov siab, qhov hnyav, thiab tawv nqaij, hom plaub hau thiab lub ntsej muag. Ib yam li ntawd, txhua yam khoom muaj lub cev muaj zog raws li lawv tau txheeb xyuas thiab siv los ntawm. Cov tshuaj kuj muaj cov khoom siv tshuaj lom neeg uas yog cov khoom uas txiav txim siab seb lawv hnov mob nrog lwm yam tshuaj thiab dab tsi tshwm sim rau lawv thaum raug oxidation lossis cua sov. Muaj ntau qhov sib txawv ntawm cov tshuaj lom neeg thiab lub cev ntawm cov khoom uas yuav tau qhia hauv kab lus no.
Feem ntau, lub cev lub cev yog cov uas tuaj yeem soj ntsuam thiab ntsuas, xws li xim, duab, hardness thiab ntom ntawm cov khoom. Ntawm qhov tod tes, cov khoom siv tshuaj lom neeg tuaj rau hauv ua ntej tsuas yog thaum ib yam khoom raug pitted tawm tsam lwm yam khoom kom pom tias muaj dab tsi tshwm sim lossis lawv ua li cas rau ib leeg. Ib qho cuab yeej zoo li no yog flammability uas txiav txim siab yuav ua li cas cov khoom yuav tsum tau ua los yog khaws cia raws li cov khoom siv hluav taws xob yooj yim dua los ntes hluav taws dua li cov khoom tsis muaj hluav taws. Ib yam li corrosion yog lwm yam khoom siv tshuaj ntawm cov khoom uas yog li cas lawv oxidize thaum lawv nkag mus rau hauv cov dej noo.
Hauv kev txiav txim siab dav dav, nws tuaj yeem hais tau tseeb tias cov khoom uas hloov cov tshuaj lom neeg ntawm cov tshuaj yog cov khoom siv tshuaj lom neeg thaum cov uas tsis ua rau muaj kev hloov pauv ntawm cov tshuaj lom neeg yog nws lub cev. Thaum koj tab tom sim hnov tsw cov tshuaj (odor), koj tsis cuam tshuam cov tshuaj hloov pauv, thiab yog li nws yog lub cev khoom. Qee qhov piv txwv ntawm lub cev muaj zog yog qhov ntom ntom, xim, melting thiab khov cov ntsiab lus, flammability, magnetism, viscosity thiab ntom. Ntawm qhov tod tes, piv txwv ntawm cov khoom siv tshuaj muaj zog yog cov tshuaj tiv thaiv nrog lwm yam tshuaj xws li dej, pH tus nqi ntawm cov tshuaj, thiab kub ntawm combustion.
Ob lub cev thiab tshuaj lom neeg pab peb kom nkag siab qhov tseem ceeb ntawm ib yam khoom xws li yuav ua li cas thiaj li siv tau cov khoom zoo tshaj plaws hauv ntau yam xwm txheej.
In luv:
Physical Properties vs Chemical Properties
• Cov khoom ntawm ib yam khoom raug cais rau hauv nws lub cev thiab cov khoom siv tshuaj.
• Thaum lub cev muaj zog tuaj yeem soj ntsuam thiab ntsuas tau yooj yim yam tsis hloov pauv cov yam ntxwv ntawm cov khoom siv tshuaj lom neeg yog cov uas txiav txim siab seb cov tshuaj coj li cas hauv cov xwm txheej sib txawv thiab nws cuam tshuam nrog lwm yam tshuaj.
