A $\displaystyle 15$ g mass of nitrogen gas is enclosed in a vessel at a temperature $\displaystyle 27^{\circ} \mathrm{C}$. Amount of heat transferred to the gas, so that rms velocity of molecules is doubled, is about :
[Take $\displaystyle \mathrm{R}=8.3 \mathrm{~J} / \mathrm{K}$ mole]
Official answer
(3)
$\displaystyle 10$ kJ
