The temperature in a room is 56 degrees celcius. What would the velocity of a sound wave be at this temperature?

365 m/s

Explanation:

The velocity of sound in air is approximated as:

v ≈ 331.4 + 0.6 T

where v is the velocity in m/s and T is the temperature in Celsius.

At T = 56:

v ≈ 331.4 + 0.6 (56)

v ≈ 365.0

The velocity is approximately 365 m/s.
