A \( 15 \mathrm{~g} \) mass of nitrogen gas is enclosed in a vessel at a temperature \( 27^{\circ} \mathrm{C} \). Amount of heat transferred to
P
the gas, so that rms velocity of molecules is doubled, is about: [Take \( \mathrm{R}=8.3 \mathrm{~J} / \mathrm{K} \) mole
(1) \( 0.9 \mathrm{~kJ} \)
(2) \( 6 \mathrm{~kJ} \)
(3) \( 10 \mathrm{~kJ} \)
(4) \( 14 \mathrm{~kJ} \)
