WebApr 12, 2024 · Flying at the speed of sound is difficult enough. But hypersonic travel is constrained by its own set of unique technical challenges. When traveling at 5 times the speed of sound air resistance generates copious amounts of heat, which requires active thermal protection for the aircraft. WebThis explains why sound travels faster through hotter air compared to colder air. The speed of sound at 20 degrees Celsius is about 343 meters per second, but the speed of sound at zero degrees Celsius is only about 331 meters per second. Remember, the only way to change the speed of sound is to change the properties of the medium it's ...

WebThus, it is reasonable that the speed of sound in air and other gases should depend on the square root of temperature. While not negligible, this is not a strong dependence. At 0°C 0 °C, the speed of sound is 331 m/s, whereas at 20.0°C 20.0 °C, it … Web21 hours ago · Mach 1 is the speed of sound. Mach 2 is twice the speed of sound, and so on.
