At normal atmospheric pressure and a temperature of 20 degrees Celsius, a sound wave will travel at approximately 343 m/s; this is approximately equal to 750 miles/hour. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature. - Definition and Factors Affecting the Speed of Sound, Working Scholars® Bringing Tuition-Free College to the Community, Temperature of freshwater = 20 °C + 273.15 = 293.15 K. {/eq} is the absolute temperature in degrees Kelvin, and {eq}m The speed of sound in an object depends also on elasticity of the object. The speed of sound varies depending on altitude, temperature and the medium through which it travels.For example, at sea level in a standard atmosphere, at a temperature of 59-degrees Fahrenheit (15 Celsius), sound travels 761 miles per hour (1,225 km/p/h). The properties that have an affect on the speed of sound in air are pressure, density, and molecular mass of the medium. Helium is considered a monatomic ideal gas. 20 Qs .
