Statement of a problem № 10688


Two ideal gases have the same temperature and the same value for g (the ratio of the specific heat capacities at constant pressure and constant volume). A molecule of gas A has a mass of 7.31 × 10226 kg, and a molecule of gas B has a mass of 1.06 × 10-25 kg. When gas A (speed of sound = 259 m/s) fills a tube that is open at both ends, the first overtone frequency of the tube is 386 Hz. Gas B fills another tube open at both ends, and this tube also has a first overtone frequency of 386 Hz. What is the length of the tube filled with gas B?
