How does temperature affect the speed of sound in a solid? Given v0 = 1000 ms⁻¹ at 0°C, find vT using vT = v0 (1 + αT).

The speed of sound in the solid at $0^\circ\text{C}$ is $v_0 = 1000 \text{ ms}^{-1}$.
The temperature change is from $0^\circ\text{C}$ to $25^\circ\text{C}$.

For many materials, the speed of sound changes approximately linearly with temperature. The general formula is:

where $v_T$ is the speed at temperature $T$, $v_0$ is the speed at $0^\circ\text{C}$, and $\alpha$ is the temperature coefficient of the speed of sound.
