Question

Sound travels in air at 0^oC with a velocity of about-
1. 370 meter/second
2. 330 meter/second
3. 350 meter/second
4. 380 meter/second

Answer 1

Correct Answer - Option 2 : 330 meter/second

The correct answer is 330 meter/second.

• The speed of sound in a medium depends on the temperature of the medium.
• The speed of sound increases as temperature increase.
• The speed of sound in air is 330 meter/second at 0 ºC.
• The speed of sound in air is 344 meter/second at 22 ºC.
• The speed of sound in oxygen gas at  25°C is 316 m/s.
• The speed of sound in water (distilled) at 25°C is 1498 m/s.

• The speed of sound in air at constant temperature does not vary with pressure.
• The speed of sound in air at constant temperature remains the same with the increase in pressure.
• Sound cannot travel in a vacuum.
• Sound travels faster in solids.
• The speed of sound decreases when we go from solid to gaseous state.
• The audible range of an average human is 20 Hz — 20 kHz.
