Txhawm rau nrhiav cov lus hais ib txwm ionization zog , tus nqi no yog muab los ntawm tus lej ntawm atoms hauv a mole ntawm hydrogen atoms (lub Avogadro tas li) thiab muab faib los ntawm 1000 los hloov joules ua rau kilojoules . Qhov no piv tau zoo nrog cov nqi ib txwm hais rau hydrogen's ionization zog ua 1312 kwm mol -1.
Ntawm no, koj yuav nrhiav tau lub zog ionization ntawm be3+ li cas?
Cov ionization zog Nws kuj yog proportional rau Z^2, vim hais tias qhov no yog qhov sib txawv ntawm lub hauv av lub xeev ntawm lub atom/ion thiab cov zog ntawm qhov sib cais ion ntxiv rau electron. Tus nqi ntawm Be^(4+) yog plaub npaug ntawm H^+, yog li tus ionization zog ntawm Be^(3+) yog 4^2 lossis 16 npaug ntawm H.
Ib yam li ntawd, lub zog ionization siv rau dab tsi? Ionization zog yog qhov tseem ceeb vim nws tuaj yeem ua tau siv rau pab kwv yees lub zog ntawm chemical bonds. Chav nyob: Ionization zog yog qhia nyob rau hauv units ntawm kilojoule ib mole (kJ/mol) los yog electron volts (eV).
Tom qab ntawd, ib tug kuj yuav nug, koj ua li cas xam ionisation peev xwm?
Faib cov huab hwm coj ionized, hauv grams, los ntawm tus lej atomic. Yog tias koj muaj 24 grams ntawm oxygen, piv txwv li, uas muaj atomic loj ntawm 16, koj muaj 1.5 moles. Multiply ionization zog koj ntsia los ntawm 96.485. 1 eV/particle yog sib npaug rau 96.485 kJ/mol.
Dab tsi yog ionization zog piv txwv?
Cov ionization zog ntawm ib qho atom yog tus nqi ntawm zog yuav tsum tshem tawm ib qho hluav taws xob los ntawm daim ntawv gaseous ntawm lub atom lossis ion. 1st ionization zog - Cov zog yuav tsum tau tshem tawm qhov siab tshaj plaws zog electron los ntawm ib tug nruab nrab gaseous atom. Rau Piv txwv : Na(g) → Na+(g) + e- Kuv1 = 496 kJ/mol.

Yuav ua li cas koj xam lub zog ntawm ib tug electromagnetic yoj?
Lub zog nqa los ntawm ib qho yoj yog proportional rau nws amplitude squared. Rau electromagnetic nthwv dej, qhov no txhais tau hais tias siv tau raws li Iave = cϵ0E202 I ave = c ϵ 0 E 0 2 2, qhov twg Iave yog qhov nruab nrab siv nyob rau hauv W / m2, thiab E0 yog qhov siab tshaj plaws hluav taws xob teb lub zog ntawm lub nruam sinusoidal yoj
Yuav ua li cas koj xam lub cev muaj zog overload tam sim no?
Faib los ntawm qhov ntsuas tag nrho load tam sim no los ntawm lub npe tsav tsheb. Qhov no yuav yog qhov tseem ceeb load rau lub cev muaj zog. Yog tias lub cev muaj zog tam sim no yog 22A thiab qhov ntsuas tag nrho tam sim no yog 20A, ces qhov ntsuas qhov ntsuas yog 22/20 = 1.1. Qhov no txhais tau tias lub cev muaj zog yog overloaded los ntawm 10%
Yuav ua li cas koj xam lub zog cua sov los ntawm dej?
Xam cov cua sov tso tawm Tom ntej no, koj siv Q = mc ∆T, piv txwv li Q = (100 + 100) x4.18 x 8. Faib qhov tshwj xeeb kub muaj peev xwm ntawm dej, 4181 joules / kg degrees Celsius los ntawm 1000 kom tau cov duab rau joules / g degrees C. Cov lus teb yog 6,688, uas txhais tau tias 6688 joules ntawm tshav kub raug tso tawm
Yuav ua li cas koj xam lub zog siv zog thiab nyob deb?
Txij li qhov kev siv zog yog lub zog ntawm ib cheeb tsam, yog tias koj faib lub zog ntawm qhov chaw los ntawm thaj tsam ntawm tus kheej, koj yuav suav qhov kev siv ntawm qhov deb ntawm r los ntawm qhov chaw. Hloov cov qauv no ua rau koj xam lub zog ntawm qhov chaw: P = 4πr2I
Yuav ua li cas koj xam dag zog hauv physics?
Nyob rau hauv ib chav kawm ib tug lever lub zog ntawm lub dag zog (Fe) multiplied los ntawm qhov kev ncua deb ntawm lub dag zog los ntawm lub fulcrum (de) yog sib npaug zos rau lub zog ntawm lub kuj (Fr) multiplied los ntawm qhov kev ncua deb ntawm qhov kev tawm tsam ntawm lub fulcrum (dr) . Kev siv zog thiab kev tawm tsam yog nyob rau sab nraud ntawm fulcrum
