Hauv ib khov kho , cov cov khoom yog packedly ua ke thiab tsis muaj kev ywj pheej txav mus rau hauv cov khoom. Molecular motion rau lub cov khoom hauv a khov kho yog nyob rau me me heev vibrations ntawm lub atomsaround lawv taag txoj hauj lwm; yog li ntawd, cov khoom khib nyiab muaj ib tug fixedshape uas nyuaj rau hloov.
Kuj nug tias, piv txwv ntawm ib qho khoom hauv ib qho khoom yog dab tsi?
A khov kho yog ib qho piv txwv ntawm cov teeb meem uas khaws nws cov duab thiab ntom thaum tsis kaw. Piv txwv ntawm cov khib nyiab yog cov lus ntsev, cov suab thaj, dej khov, cov pa roj carbon dioxide khov (cov dej khov qhuav), iav, pob zeb, hlau feem ntau, thiab ntoo. Thaum a khov kho yog rhuab, lub atom los yog molecules tau kinetic zog.
Ib yam li ntawd, cov khib nyiab puas ruaj khov? Khoom Cov hauv paus Khoom tuaj yeem nyuaj zoo li pob zeb, mos zoo li pluab, pob zeb abig zoo li lub hnub qub, lossis pob zeb me me xws li cov xuab zeb. Qhov tseem ceeb yog qhov ntawd cov khoom khib nyiab tuav lawv cov duab thiab lawv tsis ntws zoo li cov kua. Ib pob zeb yuav zoo ib yam li pob zeb tshwj tsis yog muaj ib yam dab tsi tshwm sim rau nws.
Qhov thib ob, cov khoom coj li cas hauv cov khoom?
Cov khoom nyob rau hauv a: roj yog zoo sib cais nrog tsis tu ncua. kua yog nyob ze ua ke nrog tsis tu ncua.
Particles nyob rau hauv ib tug:
- roj vibrate thiab txav mus los ntawm kev kub ceev.
- kua vibrate, txav mus, thiab swb dhau ib leeg.
- khoom vibrate (jiggle) tab sis feem ntau tsis txav ntawm qhov chaw.
Puas muaj peev xwm khiav tau?
Vim tias cov khoom tsis txav mus, cov khoom muaj qhov tseeb thiab ntim, thiab ua tau 't ntws . Vim hais tias cov particles twb tau ntim zoo ua ke, cov khib nyiab ua tau 'teasily yuav compressed. Vim tias muaj ntau cov khoom hauv qhov ntim me me, cov khib nyiab yog ntom.

Puas yog nws muaj tseeb tias nyob rau hauv kev thauj mus los ntawm kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog?
Hauv kev thauj mus los passive, kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog. _ Muaj tseeb_ 5. Endocytosis yog ib txoj kev uas ib lub cell membrane nyob ib puag ncig thiab siv cov khoom los ntawm ib puag ncig. Ib daim nyias nyias uas tso cai rau qee cov ntaub ntawv dhau los qhia txog kev xaiv permeability
Cov khoom puas muaj ob qho tib si kinetic thiab lub zog muaj peev xwm?
Ib yam khoom muaj peev xwm muaj ob qho tib si kinetic thiab lub zog muaj peev xwm tib lub sijhawm. Piv txwv li, ib yam khoom uas poob, tab sis tseem tsis tau mus txog hauv av muaj lub zog kinetic vim nws txav mus rau hauv qab, thiab lub zog muaj peev xwm vim tias nws muaj peev xwm txav mus rau hauv qab txawm tias nws twb muaj lawm
Puas yog acetone yog cov khoom sib xyaw lossis cov khoom?
Acetone yog cov kua uas tsis muaj xim, flammable kua uas evaporates yooj yim. Nws yog ib qho organic compound vim tias carbonatoms muaj nyob rau hauv acetone cov tshuaj formula, uas yog (CH3) 2O. Nws muaj peb carbon atoms, rau hydrogen atoms, thiab ib tug oxygen atom
Puas muaj qhov chaw nruab nrab ntawm cov khoom hauv cov khoom?
Feem ntau, cov khib nyiab yog denser dua cov kua, uas yog denser dua gases. Cov khoom hauv cov kua feem ntau tseem kov tab sis muaj qee qhov chaw nruab nrab ntawm lawv. Cov pa roj muaj qhov sib txawv loj ntawm lawv
Puas yog ib yam khoom uas muaj zog ib txwm muaj lub zog?
Ch 8 Xav & Piav Cov Lus Teb: Yog, ib yam khoom uas muaj zog ib txwm muaj zog. Yog tias cov khoom muaj lub zog (mv) nws yuav tsum txav mus, thiab yog tias nws txav mus, nws muaj lub zog kinetic.Tsis yog, ib qho khoom uas muaj lub zog tsis tas yuav muaj lub zog. Txij li cov khoom no lub nrawm = 0, nws lub zog yog xoom
