Lub muaj zog dua lub zog sib xyaws , qhov siab dua qhov kub ntawm fusion ntawm fusion Lub latent cua sov ntawm fusion yog qhov hloov pauv ntawm cov khoom muaj pes tsawg thaum nws melts. Thaum tshav kub ntawm fusion yog hais txog ib chav tsev ntawm qhov loj, nws feem ntau hu ua qhov tshwj xeeb kub ntawm fusion, thaum molar tshav kub ntawm fusion yog hais txog qhov hloov pauv enthalpy ib tus nqi ntawm cov khoom hauv moles. https://en.wikipedia.org › wiki › Enthalpy_of_fusion
Enthalpy ntawm fusion - Wikipedia
. Yuav ua li cas tshwm sim rau lub tshav kub ntawm vaporization raws li lub intermolecular rog nce? Qhov muaj zog ntawm cov rog intermolecular, qhov kub ntawm vaporization ntau dua. … Qhov muaj zog ntawm lub zog nruab nrab, qhov qis dua qhov vapor siab.
Puas vaporization kov yeej lub zog ntawm lub cev?
Vaporization ntawm cov qauv ntawm cov kua yog ib theem hloov ntawm cov kua theem mus rau theem roj. … Rau cov molecules ntawm cov kua kom evaporate, lawv yuav tsum nyob ze ntawm qhov chaw, yuav tsum tau tsiv mus nyob rau hauv txoj kev coj, thiab muaj txaus kinetic zog rau kov yeej intermolecular rog tam sim no nyob rau hauv cov kua theem.
Yuav ua li cas rau cov rog intermolecular thaum kub nce?
Thaum qhov kub thiab txias nce ntxiv, tus kheej cov khoom yuav muaj zog ntau heev uas cov rog sib txawv tau kov yeej, yog li cov khoom sib cais ntawm ib leeg,thiab cov khoom no dhau los ua cov pa roj (xws li xav tias lawv cov khoom siv tshuaj tsis muaj zog uas cov compound decomposes los ntawm qhov kub siab).
Dab tsi yog qhov muaj zog tshaj plaws rau lub zog tsis muaj zog tshaj plaws?
Intermolecular rog Nyob rau hauv qhov kev txiav txim ntawm qaug zog mus rau lub zog tshaj:
- dispersion force.
- Dipole-dipole force.
- Hydrogen bond.
- Ion-dipole force.
Dab tsi yog qhov muaj zog tshaj plaws ntawm lub zog hauv methane?
Vim li no lub zog muaj zog tshaj plaws ntawm CH4 molecules yog Van der Waals rog. Hydrogen daim ntawv cog lus muaj zog dua Van der Waals rog yog li NH3 thiab H2O yuav muaj cov ntsiab lus kub siab dua CH4.
