The increase in the speed of sound in air for each degree rise above 0oC is
Correct answer: D. 0.61 m/s
- A. 0.40 m/s
- B. 0.51 m/s
- C. 0.81 m/s
- D. 0.61 m/s
Explanation
The speed of sound is about 331.5 m/s at 0 degree-Celsius. The speed of sound increases by 0.6 meters per second (m/s) for every degree-Celsius increase in temperature.

About Speed of Sound
The speed of sound depends on the properties of the medium, including its elasticity and density, and in gases it varies mainly with temperature. Questions connect speed with frequency and wavelength, compare sound in solids, liquids and gases, and distinguish the speed of propagation from the oscillating particles' motion.
