alleryWork function is usually measured in:
ADegrees kelvin
BElectron volts
CMetres per hour
DKilograms force
Answer & Solution
Correct answer: B. Electron volts
1. The energies involved are far too small for joules to be handy.
2. A unit built from the electron's charge suits better.
3. Work function is quoted in electron volts.
4. So the answer is electron volts.
