Question

Sound travels in air at $0^{\circ }C$ with a velocity of about

• A. 300 m/s
• B. 330 m/s
• C. 350 m/s
• D. 380 m/s

Answer 1

The correct option is B 330 m/s

We know that velocity of sound in air at room temperature is around 350m/s

And also we know that v$\propto \sqrt{T}$ So, it's velocity will be lesser at 0${}^0$ Celsius and around 330m/s
