Raws li cov kinetic txoj kev xav, particle ntawm teeb meem nyob tas li tsab ntawv tsa suab . Cov zog ntawm tsab ntawv tsa suab hu ua kinetic zog . Cov kinetic zog ntawm particle ntawm teeb meem txiav txim lub xeev ntawm teeb meem . Cov khoom ntawm cov khoom muaj tsawg kawg nkaus kinetic zog thiab cov khoom gases muaj ntau tshaj.
Ua kom pom qhov no, qhov ntsuas ntawm lub zog kinetic ntawm cov khoom txav mus li cas?
Kub
Qhov thib ob, ua li cas cov khoom muaj kinetic zog yog lub zog kinetic cuam tshuam los ntawm tshav kub? Lub vibrational txav ntawm cov khoom hauv cov khoom yog kinetic zog . Kub ua cov cov khoom nyob rau hauv ib qho khoom vibrate sai, muab lawv ntau dua kinetic zog . Thaum ib qho piv txwv ntawm cov khoom, kua, lossis roj teeb meem heats li, nws expands. Thaum twg teeb meem tau kub, nws cov khoom nce kinetic zog.
Ib sab saum toj no, puas yog cov khoom txav mus los?
Cov hais tias tag nrho cov cov khoom uas ua teeb meem nyob tsis tu ncua. Yog li ntawd, tag nrho cov khoom hauv teeb meem muaj kinetic zog. Lub kinetic txoj kev xav ntawm teeb meem pab piav qhia lub xeev sib txawv ntawm teeb meem - Khoom, kua, thiab roj. Cov khoom tsis txhob txav ntawm tib lub nrawm.
Puas yog lub zog kinetic ntawm cov khoom hloov thaum lub sij hawm hloov ntawm lub xeev ntawm cov teeb meem?
Kev hloov ntawm lub xeev . Cov kinetic txoj kev xav ntawm teeb meem tuaj yeem siv los piav qhia seb cov khoom khib nyiab, kua thiab cov pa sib hloov tau li cas los ntawm nce los yog txo hauv kub zog . Thaum ib yam khoom yog rhuab lub zog ntawm lub cov khoom nce raws li cov cov khoom ua kom muaj zog.

Puas yog cov ntsiab lus ntawm cov teeb meem txav qhov nruab nrab ntawm lawv teb?
Cov khoom tsis tuaj yeem txav mus los. Ib qho piv txwv ntawm cov khoom khib nyiab thiab cov kua dej yog cov khoom sib txuas nrog lawv cov neeg nyob ze, uas yog, nrog rau lwm cov khoom. Yog li lawv yog incompressible thiab qhov sib txawv ntawm cov khib nyiab thiab kua distinguishesthem los ntawm gases
Lub kinetic txoj kev xav ntawm cov teeb meem cuam tshuam li cas rau cov kua dej thiab cov pa roj?
Lub kinetic molecular txoj kev xav ntawm cov teeb meem hais tias: Cov teeb meem yog tsim los ntawm cov khoom uas hloov mus tas li. Tag nrho cov khoom muaj lub zog, tab sis lub zog sib txawv nyob ntawm qhov ntsuas kub ntawm cov qauv ntawm cov teeb meem nyob hauv
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
Puas yog lub zog hauv daim ntawv ntawm kev txav yog lub zog muaj peev xwm?
Lub zog nyob rau hauv daim ntawv ntawm kev txav yog 'muaj peev xwm' zog. Qhov ntau dua 'mas' ib qho khoom txav muaj, lub zog kinetic nws muaj. Lub pob zeb ntawm ntug pob tsuas muaj 'kinetic' zog vim nws txoj hauj lwm. 'Thermal' zog yog lub zog khaws cia los ntawm cov khoom uas ncab los yog compression
Puas yog khoov ntawm lub teeb tsis nyob ib puag ncig cov teeb meem?
Diffraction yog pom ntawm lub teeb tsis muaj zog tab sis tsuas yog thaum nthwv dej ntsib teeb meem nrog cov wavelengths me me (xws li cov khoom raug tshem tawm hauv peb cov huab cua). Diffraction yog qhov khoov ntawm nthwv dej ncig obstacles thiab qhib. Tus nqi ntawm diffraction nce nrog nce wavelength
