A pipe of length 1.5m closed at one end is filled with a gas and it resonates in its fundamental with a tuning fork. Another pipe of the same length but open at both ends is filled with air and it also resonates in its fundamental with the same tuning fork. Calculate the velocity of sound at  $0^{0}C$ in the gas .Gives that the velocity of sound in air is $360 m/s$ at ${30}^0$C where the experiment is performed.................(given that $\sqrt{\frac{273}{303}}=0.95$)
