Question

An electron volt is larger than a joule.

• A. True
• B. False

Answer 1

The correct option is B False

1. The energy gained by an electron when the electrical potential at the electron increases by one volt is measured in electron volts (eV).
2. In the International System of Units or SI units, a joule (J) is a derived unit of energy.
3. eV and Joule have a proportional relationship.

$1eV=1.602\times {10}^{-19}J$

Thus the statement is false, an electron volt is smaller than joule.
