On two different days, velocity of soundthrough atmospheric air was measured as321 m/s and 322.53 ms. The approximatedifference in room temperature on, these twodays is(a) zero(d) 1.53°C (e) 15.3°C(c) 2.5°C |

Answer» The speed is proportional to the square root of the absolute temperature, giving an increase of about 0.6 m/s per degree Celsius. 0.6 m/s due to the change of 1 degree Celsius. 1 m/s due to the change of 1/0.6 degree Celsius. 1.53 m/s due to the change of 1/0.6 * 1.53 = 2.55 degree Celsius. |
