London dispersion rog London dispersion rog London dispersion rog (LDF, tseem hu ua dispersion rog, London rog, instantaneous dipole-induced dipole rog, Fluctuating Induced Dipole Bonds los yog xoob li van der Waals rog) yog ib hom quab yuam ua ntawm atoms thiab molecules uas ib txwm muaj hluav taws xob sib luag; uas yog, cov electrons yog … https://en.wikipedia.org › wiki › London_dispersion_force
London dispersion force - Wikipedia
, nyob rau hauv qeb ntawm van der Waal rog: Cov no yog cov tsis muaj zog tshaj plaws ntawm cov rog intermolecular thiab muaj nyob nruab nrab ntawm txhua hom molecules, txawm tias ionic lossis covalent-polar lossis nonpolar. Qhov ntau electrons ib molecule muaj, lub zog ntawm London dispersion rog yog.
Dab tsi yog qhov muaj zog tshaj plaws thiab tsis muaj zog ntawm kev nyiam ntawm cov molecules?
Muaj peb hom sib txawv ntawm lub zog sib txawv ntawm lub zog. Lawv yog (muaj zog tshaj plaws rau qhov tsis muaj zog tshaj) hydrogen bonding, dipole-dipole thiab Van der Waals 'force.
Yuav ua li cas lub zog ntawm kev nyiam ntawm cov molecules tsawg kawg?
Txoj kev | Luv/Long Answer Questions
Kev daws: Lub zog ntawm kev nyiam ntawm cov molecules ntawm cov teeb meem hu ua lub zog intermolecular ntawm attraction. Nws yog qhov siab tshaj plaws hauv cov khib nyiab, tsawg dua hauv cov kua thiab tsawg kawg hauv gases.
Lub xeev twg yog lub xeev thib tsib?
Qee zaum hu rauRaws li 'lub xeev thib tsib ntawm qhov teeb meem', a Bose-Einstein Condensateyog lub xeev ntawm cov teeb meem tsim thaum cov khoom, hu ua bosons, txias kom ze ze rau xoom (-273.15 degrees Celsius, lossis - 460 degrees Fahrenheit).
Dab tsi yog lub zog sib xyaw ua ke uas muaj zog tshaj plaws?
Lub zog muaj zog tshaj plaws yog hydrogen bonding, uas yog ib qho tshwj xeeb ntawm kev sib cuam tshuam ntawm dipole-dipole uas tshwm sim thaum lub hydrogen nyob ze ze (kho rau) lub ntsiab lus electronegative heev (xws li oxygen, nitrogen, lossis fluorine).
