4.0 \mathrm{~g}

of helium occupies

22400 \mathrm{~cm}^3

at STP. The specific heat capacity of helium at constant pressure is

5.0\, \mathrm{cal} \mathrm{K}^{-1} \mathrm{~mol}^{-1}

. Calculate the speed of sound in helium at STP.

View answer and explanation

Correct option: C

962.28 m/s

Option C (962.28 m/s) is correct because it is the result of correctly applying the formula for the speed of sound in a gas, considering the adiabatic index and STP conditions.

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
