What is the approximate average thermal energy of an electron in a solid at room temperature?
A) 0.00
B) $0.0010 \mathrm{eV}$
C) $0.025 \mathrm{eV}$
D) $1.0 \mathrm{keV}$
E) $27 \mathrm{eV}$

Question

Quizplus · Accepted Answer

The average thermal energy of particles, including electrons, at room temperature (approximately 300 K) can be estimated using the formula $kT$, where $k$ is the Boltzmann constant ($8.617 \times 10^{-5} \mathrm{eV/K}$) and $T$ is the temperature in Kelvin. Multiplying these gives an energy of about $0.025 \mathrm{eV}$, making option C correct.
