Question

detemine the speed to sound at atomperature of 5'c​

Answer 1

Answer:

If the temperature is TC = 20 °C (T = 293 K), the speed of sound is v = 343 m/s. The equation for the speed of sound in air v = √γRTM can be simplified to give the equation for the speed of sound in air as a function of absolute temperature: v=√γRTM=√γRTM(273K273K)=√(273K)γRM√T273K≈331m/s√T273K. v=fλ.

Answer 2

The speed of sound at a temperature of 20⁰C ( T = 293K) is 343ms⁻¹.

The equation for the speed of sound in air, v = √γRTM.

Speed of sound is related to temperature as velocity is directly proportional to the square root of temperature in Kelvin.

Putting the temperature in the equation, 343 = √γR(293)M

Now the temperature 5°C into Kelvin = 273+5 = 278K

Now, v = √γR(278)M

Dividing both equations,

(343 = √γR(293)M) / (v = √ γR(278)M)

v = 343 × √278 / √293

v = 334.1 ms⁻¹

Therefore, the speed of sound at a temperature of 5°C is 334.1 ms⁻¹.
