The temperature dependence of the speed of sound is described by the equation
v≈(331+0.6T/∘C)m/sv≈(331+0.6T/∘C)m/s {"version":"1.1","math":"v\approx (331 + 0.6 \,T /\, ^\circ\mathrm{C})\:\mathrm{m/s}"}
Since the lab may not be exactly at 20 °C, the value for the speed of sound that you will measure may be different from 343 m/s.
Assuming that the temperature in the lab is somewhere between 10 °C and 30 °C, the measured speeds of sound should be in the range

the measured speed of sound from longer pipe is 1006.1 +/- 80 m/s Q6. (1) Using the measured speed of sound from longer pipe, estimate the temperature of the lab room, with uncertainty. The speed of sound is given by v 331 +0.6T (m/s), where T is the temperature in degrees Celsius. Does this find the lab room to be significantly warmer or colder than room temperature (say, 20+20C)? Justify using your uncertainties. Also, does this result make sense? Does...
An open organ pipe emits F (349 Hz ) when the temperature is 14 ∘C. The speed of sound in air is v≈(331+0.60T)m/s, where T is the temperature in ∘C. Part C What is frequency of the fundamental standing wave in the pipe? Part E What is the wavelength in the traveling sound wave produced in the outside air?
The speed of sound in room temperature (20?C) air is 343 m/s; in room temperature helium, it is 1010 m/s. The fundamental frequency of an open-closed tube is325Hz when the tube is filled with air. What is the fundamental frequency if the air is replaced with helium?

V. HEAT CAPACITY OF PLATINUM The usual expression for the Debye temperature involves the speed of sound, v. However, this result is too simplistic because there are two types of waves in the solid: transverse waves which travel at a speed of v, and longitudinal waves, which travel at a speed of vi. In general these speeds are not the same. a) [2 marks] Derive a new expression for the Debye temperature using the identity that the aver- age speed...
The speed of sound in air (in m/s) depends on the temperature according to the approximate expression below, where TC is the Celsius temperature. In dry air the temperature decreases about 1°C for every 150 m rise in altitude. v = 331.5 + 0.607TC (a) Assuming this change is constant up to an altitude of 9000 m, how long will it take the sound from an airplane at 8800 m to reach the ground on a day when the ground...
Part A What must the initial speed of a lead bullet be at a temperature of 23.0 ∘C so that the heat developed when it is brought to rest will be just sufficient to melt it? Assume that all the initial mechanical energy of the bullet is converted to heat and that no heat flows from the bullet to its surroundings. (Typical rifles have muzzle speeds that exceed the speed of sound in air, which is 346 m/s at 23.0...
