Chapter 12, Problem 71GP

To determine

The increase in velocity of sound in summers as compared to winters, along with the explanation and the assumptions made, using the expression $v=\sqrt{\frac{\gamma RT}{M}}$, where $R$ is the Universal gas constant which is equal to $8.314\text{ J/mol}\cdot \text{K}$, $T$ is the absolute temperature, $M$ is the molar mass of the gas in $\text{kg/mol}$, and $\gamma$ is the characteristic of the specific gas which is equal to $1.4$ for air. The average molar mass of dry air is $28.95\text{ g/mol}$.
