A vessel contains

14 \mathrm{~g}

of nitrogen gas at a temperature of

27^{\circ} \mathrm{C}

. The amount of heat to be transferred to the gas to double the r.m.s speed of its molecules will be:

Take

R=8.32 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}

View answer and explanation

Correct option: C

9360 J

Option C (9360 J) is correct because it is the amount of heat required to double the RMS speed, calculated using the specific heat at constant volume.

Assertion: The pressure exerted by an enclosed ideal gas does not depend on the shape of the container.
Reason: The pressure of an ideal gas depends on the number moles, temperature and volume of the enclosed If
