Teeb meem yog ib txwm Hloov daim ntawv, qhov loj me, cov duab, xim, thiab lwm yam. Muaj 2 hom kev hloov qhov teeb meem tau dhau mus. Phase Hloov yog PHYSICAL PHEM !!!!! TAG NRHO theem hloov yog tshwm sim los ntawm kev ntxiv lossis TAKING tawm lub zog !!!

Ua raws li qhov no saib, puas hloov pauv lub cev lossis tshuaj hloov pauv?

Phase Hloov . Theem hloov yog kev hloov ntawm lub cev uas tshwm sim thaum muaj teeb meem kev hloov lub zog hais, tab sis tshuaj bonds tsis tawg los yog tsim. Cov theem ntawm ib yam khoom nyob ntawm seb lub zog ntawm cov atoms muaj. Tag nrho cov atoms yog nyob rau hauv kev txav.

Tsis tas li ntawd, dab tsi ua rau kev hloov pauv theem? Hloov cov nqi hluav taws xob feem ntau ua rau kub hloov . Txawm li cas los xij, DURING lub theem hloov , qhov kub nyob twj ywm tib yam txawm tias lub zog cua sov kev hloov . Lub zog no yog qhia rau kev hloov pauv theem thiab tsis mus nce qhov kub thiab txias.

Xav txog qhov no, hom kev hloov pauv hauv cov tshuaj twg yog ib txwm hloov pauv lub cev?

A hloov lub cev koom nrog a hloov hauv lub cev khoom. Piv txwv ntawm lub cev cov khoom muaj xws li melting, hloov mus rau ib tug gas, hloov ntawm lub zog, hloov ntawm durability, kev hloov mus rau crystal daim ntawv, textural hloov , puab, loj, xim, ntim thiab ntom.

Dab tsi yog 6 theem sib txawv?

Muaj rau qhov kev hloov pauv ntawm theem uas cov tshuaj mus txog:

  • Freezing: kua rau khoom.
  • Melting: solid to liquid.
  • Condensation: gas rau kua.
  • Vaporization: kua rau roj.
  • Sublimation: solid to gas.
