Show that the fractional change in the speed of sound (dv/v) due to a very small temperature change dT is given by dv/v = (1/2)*dT/T. (Hint: Start with equation v = square root (γRT/M).
Part B
The speed of sound in air at 20°C is found to be 344 m/s. Use the result in part A to find the change in the speed of sound for a 1.0°C change in air temperature.
Express your answer using two significant figures.
delta v = m/s
