Gases, kua thiab cov khoom khib nyiab tag nrho yog tsim los ntawm atoms, molecules, thiab / lossis ions, tab sis cov cwj pwm ntawm cov khoom no txawv nyob rau hauv peb theem. Gas tau zoo sib cais tsis tu ncua. ua kua nyob ze ua ke nrog tsis muaj kev npaj. khov kho yog nruj nreem ntim, feem ntau nyob rau hauv ib tug tsis tu ncua qauv.

Hais txog qhov no, qhov piv txwv ntawm cov khoom ua kua yog dab tsi?

Ib qho khoom tig mus rau hauv cov kua yog hu ua "melting." Feem ntau piv txwv yog dej khov yaj rau dej . Ntau yam khoom muaj nyob rau ntawm qhov qis dua thiab cov kua dej siab tshaj qhov ntsuas kub. Qhov ntawd yog qhov melting point ntawm cov khoom ntawd. Thaum rhuab saum qhov kub, cov khoom ua kua.

Dab tsi yog cov piv txwv ntawm cov kua thiab cov pa roj? A gas tsis muaj cov duab uas tau hais tseg lossis ntim, yog li nws tuaj yeem nthuav dav kom sau txhua qhov loj lossis cov duab ntawm lub thawv. Particle hauv cov pa yog dav sib cais, piv rau cov nyob rau hauv kua thiab cov khoom khib nyiab.

Piv txwv ntawm Gases

  • Cua.
  • Cov pa roj.
  • Hydrogen.
  • Cov pa roj carbon dioxide.
  • Dej vapor.
  • Freon.
  • Ozone.
  • Nitrogen.

Ib yam li ntawd, cov khib nyiab thiab kua sib txawv li cas?

A khov kho yog ib lub xeev ntawm teeb meem uas muaj cov duab meej thiab ntim thaum a ua kua yog lub xeev ntawm cov teeb meem uas muaj ntim tab sis tsis muaj cov duab meej. 2. A ua kua siv cov duab ntawm lub thawv uas tuav nws thaum a khov kho muaj ib lub cev ntawm nws tus kheej. Khoom muaj zog, tawv, elastic, ductile, thiab saj zawg zog thaum kua tsis yog.

Cov piv txwv ntawm cov kua yog dab tsi?

Hauv chav sov, piv txwv ntawm kua xws li dej, mercury, zaub roj, ethanol. Mercury yog tus tsuas yog metallic element uas yog a ua kua nyob rau hauv chav tsev kub, txawm tias francium, cesium, gallium, thiab rubidium liquefy ntawm qhov kub siab me ntsis.
