2024 Tus sau: Fiona Howard | [email protected]. Kawg hloov kho: 2024-01-10 06:38
Astronomers siv electron volts rau ntsuas lub zog ntawm hluav taws xob hluav taws xob, lossis photons, hauv x-ray thiab gamma-ray wavebands ntawm electromagnetic spectrum, thiab tseem siv hluav taws xob volts los piav txog qhov sib txawv ntawm atomic lossis molecular zog lub xeev uas ua rau muaj ultraviolet, pom, lossis infrared kab, lossis …
Electronvolt txhais li cas?
George Lebo, University of Florida: Ib qho hluav taws xob hluav taws xob (eV) yog lub zog uas ib qho hluav taws xob tau txais thaum nws mus los ntawm lub peev xwm ntawm ib lub volt . … Numberally one eV sib npaug 1.6x10-19 joules lossis ib joule yog 6.2x1018 eV.
electron volt yog dab tsi thiab nws qhov tseem ceeb?
electron volt, unit ntawm lub zog uas nquag siv hauv atomic thiab nuclear physics , sib npaug ntawm lub zog tau txais los ntawm ib qho hluav taws xob (ib qho khoom siv hluav taws xob nqa hluav taws xob) thaum hluav taws xob muaj peev xwm ntawm electron nce los ntawm ib volt. Cov hluav taws xob hluav taws xob sib npaug 1.602 × 10 - 12 erg, lossis 1.602 × 10- 19 joule.
Vim li cas los ntawm eV hauv chemistry?
CHEMISTRY GLOSSARY
Electron volt (eV) is a non-SI unit of energy siv hauv atomic thiab nuclear physics, sib npaug li kwv yees li 1.602 177 × 10- 19 J. Cov hluav taws xob hluav taws xob txhais tau tias yog lub zog kinetic tau los ntawm ib qho hluav taws xob thaum nrawm los ntawm qhov sib txawv ntawm 1 V
Koj txhais li cas los ntawm ib qho hluav taws xob hluav taws xob?
1 eV txhais tau tias yog lub zog tau txais los ntawm lub tshuab hluav taws xob thaum nws tau nrawm los ntawm qhov sib txawv ntawm 1 volt, li no 1 eV=1.60210- 19J
