1 Teb. Cov khoom muaj ib ruaj khov thiab tuav a ruaj ntim . Vim hais tias cov khoom nyob rau hauv cov kua yog nyob sib ze heev (Nyem sib nrug tshaj nyob rau hauv cov khoom khib nyiab ) ua kua ua tsis yooj yim compress, yog li lawv ntim yog tsau . Gases kuj tuaj yeem ntws, yog li nyob hauv puab ntawm lawv lub thawv tag nrho.
Ua li no, vim li cas cov khoom muaj qhov ruaj khov thiab lub ntim meej?
SOLIDS muaj ib cov duab meej thiab a ruaj ntim vim lawv cov molecules yog nruj nreem ntim thiab tsis txhob muaj ib yam puab nruab nrab ntawm lawv. Yog li, nws ua tau yuav hais tias cov khoom muaj qhov ruaj khov thiab ruaj ntim.
Ib yam li ntawd, qhov zoo li cas thiab ntim ntawm cov khoom yog dab tsi? A khov kho muaj tseeb ntim thiab puab , kua muaj qhov tseeb ntim tab sis tsis muaj tseeb puab , thiab cov pa roj tsis muaj qhov tseeb ntim tsis yog puab.
Tsuas yog li ntawd, puas yog lub ntim ruaj khov?
Txhua yam uas yog a khov kho muaj ib meej puab thiab a meej ntim . Cov molecules hauv a khov kho nyob hauv tsau txoj hauj lwm thiab nyob ze ua ke. Txawm hais tias cov molecules tseem tuaj yeem vibrate, lawv tsis tuaj yeem txav los ntawm ib feem ntawm khov kho mus rau lwm qhov. Yog li ntawd, a khov kho tsis yooj yim hloov nws cov duab lossis nws ntim.
Vim li cas cov kua muaj qhov ntim ruaj khov tab sis tsis ruaj khov?
Cov kua muaj ib taag ntim tab sis tsis muaj qhov ruaj khov . Qhov no yog vim cov particles nyob rau hauv a ua kua yog sib nrug tshaj qhov hais nyob rau hauv ib qho khoom, cia lawv yooj yim swb dhau ib leeg. Khoom muaj ib ruaj khov vim lawv cov molecules yog nruj nreem ntim lawv tsis tuaj yeem ua ntau tshaj vibrate tawm tsam ib leeg.

Vim li cas roj tsis muaj qhov ruaj khov?
Cov molecules hauv cov pa roj yog sib nrug heev. Yog li ntawd, cov roj gases tsis muaj qhov ntim ruaj khov lossis cov duab ruaj khov. Piv txwv li nyob rau hauv cov khib nyiab, nws muaj qhov ruaj khov thiab lub ntim ruaj khov vim tias cov molecules hauv cov khoom yog sib ze thiab nruj nreem ntim ua ke. Nws yuav siv lub thawv uas nws muab tso rau hauv
Dab tsi tsis muaj qhov ntim ruaj khov lossis zoo li cas?
Cov roj yog ib yam khoom uas tsis muaj qhov ntim thiab tsis muaj qhov tseeb. Khoom thiab kua muaj ntim uas tsis hloov tau yooj yim. Ib qho roj, ntawm qhov tod tes, muaj qhov ntim uas hloov pauv kom haum rau qhov ntim ntawm nws lub thawv. Cov molecules nyob rau hauv ib tug roj yog sib nrug heev piv nrog rau cov molecules nyob rau hauv ib tug khoom los yog kua
Puas yog cov pa roj tsis muaj qhov ruaj khov thiab ntim?
Cov roj yog ib yam khoom uas tsis muaj qhov ntim thiab tsis muaj qhov tseeb. Khoom thiab kua muaj ntim uas tsis hloov tau yooj yim. Ib qho roj, ntawm qhov tod tes, muaj qhov ntim uas hloov pauv kom haum rau qhov ntim ntawm nws lub thawv. Cov molecules nyob rau hauv ib tug roj yog sib nrug heev piv nrog rau cov molecules nyob rau hauv ib tug khoom los yog kua
Yam khoom twg tsis muaj qhov ruaj khov thiab tsis muaj qhov ntim ruaj khov?
Cov theem ntawm cov teeb meem uas tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog cov roj. Cov roj tsis muaj qhov ruaj khov
Nws hu li cas thaum cov khoom nyob hauv qhov chaw ruaj khov thiab vibrate ntawm qhov chaw?
Daim duab 2.1 Cov khoom nyob rau hauv cov khoom yog tsau rau lawv cov neeg nyob ze. Lawv vibrate ib ncig ntawm lawv txoj hauj lwm ruaj. Aerosols vam khom rau cov khoom khib nyiab, kua thiab roj thiab lawv coj li cas. Txoj kev xav uas piav txog qhov no yog Kinetic Theory of Matter
