    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...
