Yog li, thaum cov kua boiled ces nws cov molecules kis mus thiab hloov mus rau hauv roj. Qhov ntawd hu ua Evaporation . Tab sis thaum cov khoom yog rhuab (xws li dej khov, hlau los yog cov matels thiab lwm yam) yooj yim, transformation ntawm kua rau roj yog hu ua Evaporation andtransformation of solid to liquid hu ua Melting.

Ua raws li qhov no, qhov sib txawv ntawm melting thiab evaporation yog dab tsi?

Raws li lub npe qhov sib txawv ntawm vaporization thiab yaj yog tias vaporization yog ib tug hloov dua siab tshiab ntawm ib tug solidor ib cov kua rau hauv ib tug roj thaum yaj yog tus txheej txheem ntawm kev hloov lub xeev ntawm ib yam khoom los ntawm cov khoom rau cov kua los ntawm cua sov nws dhau los yaj taw tes.

qee qhov piv txwv ntawm melting yog dab tsi? Piv txwv li:

  • Melting Ice rau kua dej.
  • Melting ntawm hlau (yuav tsum tau kub heev)
  • Melting ntawm mercury thiab Gallium (ob leeg yog kua ntawm chav tsev kub)
  • Melting ntawm butter.
  • Melting ntawm tswm ciab.

Ntawm no, qhov txawv ntawm melting thiab boiling yog dab tsi?

Lub ntsiab qhov sib txawv ntawm boiling point thiab yaj point yog tias qhov yaj point yog txhais asthe kub ntawm cov khoom thiab cov theem ua kua yog inequilibrium, whereas lub boiling point yog qhov kub ntawm qhov vapor siab ntawm cov kua yog sib npaug rau sab nraud.

Yuav ua li cas rau particles thaum lawv yaj?

Thaum ib qho khoom yog rhuab rau cov khoom nce zog thiab pib vibrate sai thiab sai. Cov cov khoom nyob rau hauv cov kua yog tib yam li nyob rau hauv cov khoom tab sis lawv muaj zog dua. Rau yaj lub zog muaj zog yuav tsum kov yeej theattractions ntawm lub cov khoom thiab cia lawv rub lawv sib nrug.
