Question

The velocity of sound in air at 27°C is 340 m/s. Calculate the velocity of sound in air at 127°C.

Answer 1

I guess the velocity of sound in air at 127 c is 392.6m/s

Answer 2

Answer:

392.6 m/s

Explanation:

Given The velocity of sound in air at 27°C is 340 m/s. Calculate the velocity of sound in air at 127°C.

We need to calculate velocity of sound in air at 127 degree celsius.

  Now to convert into kelvin we have 27 + 273 = 300 and 127 + 273 = 400

 We know that C1 / C2 = √T1/T2

                          340 / C2 = √300 / 400

                         340 / C2 = √3 / 2

                            C2 √3 = 680

                           C2 = 680 / √3

                           C2 = 392.59

                            C2 = 392.6 m / s

So velocity of sound in air at 127 degree celsius is 392.6 m / s
