Question

(B) Given energy $E = 13.6 eV$.We know that $1 eV = 1.6 	imes 10^{-19} J$.Therefore, $E = 13.6 	imes 1.6 	imes 10^{-19} J = 21.76 	imes 10^{-19} J

Vedclass · Accepted Answer

$6.04 	imes 10^{-25} kWh$

Vedclass · Answer

(B) Given energy $E = 13.6 eV$.We know that $1 eV = 1.6 	imes 10^{-19} J$.Therefore, $E = 13.6 	imes 1.6 	imes 10^{-19} J = 21.76 	imes 10^{-19} J$.To convert Joules $(J)$ to kilowatt-hours $(kWh)$, we divide by $(1000 	imes 3600)$ because $1 kWh = 1000 W 	imes 3600 s = 3.6 	imes 10^6 J$.$E = \frac{21.76 	imes 10^{-19}}{3.6 	imes 10^6} kWh$.$E \approx 6.04 	imes 10^{-25} kWh$.

An energy of $13.6 eV$ is equal to
