Daim duab 2.1 The cov khoom nyob rau hauv ib qho khoom muaj tsau rau lawv cov neeg nyob ze. Lawv vibration nyob ib ncig ntawm lawv tsau txoj hauj lwm . 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.

Kuj nug, nyob rau hauv lub xeev twg yog cov hais tsuas muaj peev xwm vibrate nyob rau hauv ib tug taag txoj hauj lwm?

Khoom

Tom qab ntawd, lo lus nug yog, qhov chaw nruab nrab ntawm cov khoom hu ua dab tsi? nws yog hu ua intermolecular qhov chaw muaj nyob rau hauv nruab nrab ntawm qhov teeb meem.

Tib neeg kuj nug tias, cov khoom hauv cov khib nyiab ua li cas thaum lawv tawg tawm ntawm lawv txoj haujlwm ruaj khov?

Thaum a khov kho yog cua sov, nws particle nce zog thiab vibrate ntau dua. Vim qhov nce hauv vibrations, lub khov kho nthuav. Thaum melting point, lub cov khoom vibrate heev li lawv tawg tawm ntawm lawv txoj haujlwm . Nws yog nyob rau ntawm no tias a khov kho ua kua.

Dab tsi tshwm sim rau cov khoom thaum lub sij hawm sublimation?

- Sublimation . Cov txheej txheem uas cov khoom hloov pauv ncaj qha mus rau ib qho roj hu ua sublimation . Nws tshwm sim thaum lub cov khoom ntawm ib tug khoom absorb txaus zog kom kov yeej lub zog ntawm attraction ntawm lawv. Cov khoom carbon dioxide hloov ncaj qha mus rau lub xeev gaseous.
