Problem

In a laboratory, the measured speed of sound in air at

25^{\circ}\text{C}

340\,\text{m\,s}^{-1}

. The air has density

1.20\,\text{kg\,m}^{-3}

and is at a pressure of

1.013\times10^{5}\,\text{Pa}

. Using these data: 1. Determine the value of

\gamma

for air. 2. Calculate the percentage error in Newton’s prediction compared with the measured speed. The percentage error (to two significant figures) is a)

17.0\%

14.6\%

3.0\%

10.9\%
