Answer:

Nuestro mejor amigo escuchará la música más rápido a una temperatura de 36 ºC (309.15 K)

Explanation:

Supongase que el aire se comporta como un gas ideal y que experimenta un proceso adiabático, entonces la velocidad del sonido (v), medida en metros por segundo, queda traducida en la siguiente fórmula:

v = \sqrt{\frac{\gamma \cdot R_{u}\cdot T}{M} } (1)

Donde:

\gamma - Coeficiente de dilatación térmica, sin unidad.

R_{u} - Coeficiente universal de los gases ideales, medido en kilogramo-metros cuadrados por mol-Kelvin-segundo cuadrado.

T - Temperatura, medida en Kelvin.

M - Masa molar, medida en kilogramos por mol.

Como se puede ver, la velocidad del sonido es directamente proporcional a la raíz cuadrada de la temperatura. Por tanto, nuestro mejor amigo escuchará la música más rápido a una temperatura de 36 ºC (309.15 K)
