Qhov sib txawv tseem ceeb ntawm macroscopic thiab microscopic zog yog cov khoom macroscopic yog cov khoom ntawm cov teeb meem nyob rau hauv ntau qhov chaw microscopic yog cov khoom ntawm cov khoom ntawm cov teeb meem hauv ntau.
Lo lus microscopic hais txog txhua yam uas pom tsis tau ntawm qhov muag liab qab. Yog li, cov khoom siv microscopic hais txog cov khoom ntawm cov teeb meem ntawm qib microscopic. Txawm li cas los xij, lo lus macroscopic hais txog tej yam uas peb tuaj yeem pom ntawm qhov muag liab qab. Yog li, cov khoom macroscopic yog cov khoom ntawm cov teeb meem hauv qib pom. Ntxiv mus, units ntawm kev ntsuas yog txawv rau ob hom khoom no.
Macroscopic Properties yog dab tsi?
Macroscopic cov khoom ntawm cov teeb meem yog cov khoom hauv cov teeb meem ntau. Cov khoom no tshwm sim raws li qhov muaj pes tsawg leeg ntawm cov teeb meem tau teeb tsa hauv qhov teeb meem thiab yuav ua li cas cov khoom nyob ua ke. Cov no yog cov khoom uas tuaj yeem pom los ntawm qhov muag liab qab; yog li, peb tuaj yeem ntsuas tau yooj yim. Qee qhov piv txwv ntawm macroscopic muaj xws li siab, ntim, kub, thiab lwm yam.
Daim duab 01: Gas Siab - ib qho khoom Macroscopic
Piv txwv li, yog tias peb xav txog pob zeb diamond thiab graphite, ob qho tib si cov qauv no yog tsim los ntawm cov pa roj carbon atoms nkaus xwb, tab sis qhov kev npaj ntawm cov pa roj carbon atoms txawv ntawm ib leeg. Yog li ntawd lawv cov khoom macroscopic kuj txawv ntawm ib leeg; qhov ntom thiab hardness ntawm pob zeb diamond yog siab heev piv rau graphite thiab ntim ntawm ob lub qauv sib txawv yog tias peb xav txog qhov sib xws vim lawv muaj qhov sib txawv. Cov kev sib txawv ntawm cov khoom no tshwm sim vim qhov sib txawv ntawm cov pa roj carbon atoms thiab cov tshuaj sib txawv uas tuav lawv ua ke.
Dab tsi yog Microscopic Properties?
Cov khoom siv microscopic yog cov khoom ntawm cov khoom sib xyaw ntawm cov teeb meem loj. Qhov ntawd txhais tau tias; Cov no yog cov khoom ntawm atoms, ions lossis molecules ntawm cov teeb meem uas tsim cov teeb meem. Cov khoom siv no tsis pom ntawm qhov muag liab qab; Yog li ntawd, cov units ntawm kev ntsuas kuj txawv ntawm qhov ntsuas macroscopic. Piv txwv li, cov kev ntsuas yog muab nyob rau hauv millimeters, micrometers, nanometers, picometers, thiab lwm yam.
Qhov txawv ntawm Macroscopic thiab Microscopic Properties yog dab tsi?
Lo lus "macroscopic" yog hais txog cov khoom loj uas pom ntawm qhov muag liab qab thaum lo lus "microscopic" yog hais txog cov khoom me me uas pom tsis tau ntawm qhov muag liab qab. Yog li, qhov sib txawv tseem ceeb ntawm macroscopic thiab microscopic zog yog tias cov khoom macroscopic yog cov khoom ntawm cov teeb meem hauv ntau, whereas microscopic zog yog cov khoom ntawm cov khoom ntawm cov teeb meem hauv ntau. Hauv lwm lo lus, cov khoom siv microscopic tsis pom ntawm qhov muag liab qab, tab sis cov khoom macroscopic pom ntawm qhov muag liab qab.
Ntxiv mus, cov ntsuas ntsuas rau cov khoom no kuj txawv; rau cov khoom macroscopic, chav ntsuas ntsuas yog nyob ntawm qhov ntsuas uas pom ntawm qhov muag liab qab. Qhov no suav nrog centi-, kilo-, mega-, thiab lwm yam. Rau cov khoom siv microscopic, chav ntsuas ntsuas yog nyob ntawm qhov ntsuas uas pom tsis tau ntawm qhov muag liab qab thiab suav nrog milli-, micro-, nano-, pico-, thiab lwm yam.
Summary – Macroscopic vs Microscopic Properties
Lo lus "macroscopic" yog hais txog tej yam loj uas pom ntawm qhov muag liab qab. Lo lus "microscopic" yog hais txog tej yam me me uas tsis pom qhov muag liab qab. Yog li, qhov sib txawv tseem ceeb ntawm macroscopic thiab microscopic zog yog tias cov khoom macroscopic yog cov khoom ntawm cov teeb meem nyob rau hauv ntau qhov chaw microscopic yog cov khoom ntawm cov khoom ntawm cov teeb meem hauv ntau. Hauv lwm lo lus, cov khoom siv microscopic tsis pom ntawm qhov muag liab qab tab sis cov khoom macroscopic pom ntawm qhov muag liab qab.
