Singly charged gas ions are accelerated from rest through a voltage of $13\mathrm{.}5$V$.$ Hint

What is the kinetic energy of the gas ion after being accelerated?

KE$=2\mathrm{.}161018$Correct $$ J$.$

At what temperature, is the thermal kinetic energy of gas molecule equal to the kinetic energy of the gas ion above? Hint for $($b$)$

The thermal kinetic energy of gas molecule is equal to the kinetic energy of the gas ion above at $$ K$.($Yes$,$ on this scale, the thermal energy is that small.$)$
