• Sound Speed in Helium. The speed of sound in helium at 0°C is about 972 m/s, compared to 331 m/s in air. This is consistent with the general relationship for sound speed in gases since the density of helium is so much less than that of air.. The high speed of sound is responsible for the amusing Donald Duck voice which occurs when someone has breathed in helium from a balloon
• Higher temperatures lower the density of a medium, which puts less resistance on the sound waves. For example, sounds travels 1,087 feet per second through air at a temperature of 32 degrees Fahrenheit. At a higher temperature of 68 F, the air density is significantly lower and sound is able to travel at 1,127 feet per second

Throughout this experiment, you must be sure that the lower end of the glass tube is submerged beneath the surface of the water (see diagram below) so that you will be working with a tube that is closed at one end The high value for rms speed is reflected in the speed of sound, which is about 340 m/s at room temperature. The higher the rms speed of air molecules, the faster sound vibrations can be transferred through the air Calculate the speed of sound by dividing the speed that the sound traveled (from Step 6) by how long it took to travel that distance (from Step 7). Record the outdoor temperature that day. Repeat this experiment on days that have very different temperatures The speed at which sound propagates (or travels from its source) is referred to as the Speed of Sound (or SOS). The speed of sound is directly influenced by both the medium through which it travels and the factors affecting the medium, primarily temperature and humidity for gases like air, and additional material properties for media such as liquids and solids
