WebSep 15, 2024 · Determine the temperature in which the speed of sound in air doubles its value at 127°C. Solution 1: Assume that the initial sound’s speed in air is v. Let v be the initial speed of sound in air. v ′ = 2 v is the final speed. T=127°C=400 K is the initial temperature of the air. Let T′ represent the final temperature. WebApr 29, 2024 · In this activity, students make sense of and use real world data to investigate a variety of phenomena including the speed of sound, waves, air pressure, humidity, and temperature at high altitude. Using data collected with payload sensors attached to a high-altitude balloon students examine, interpret, verify theoretical speed of sound equations.

Webthe speed of sound is v sound = m/s = ft/s = mi/hr. ... For helium, γ = 5/3 and the molecular mass is .004 kg/mol, so its speed of sound at the same temperature is . v sound in helium = m/s = ft/s = mi/hr. Doing this calculation for air at 0°C gives v sound = 331.39 m/s and at 1°C gives v sound = 332.00 m/s. This leads to a commonly used ... WebThe speed of sound is given by: (1) v = γ P ρ where P is the pressure and ρ is the density of the gas. γ is a constant called the adiabatic index. This equation was first devised by Newton and then modified by Laplace by introducing γ. The equation should make intuitive sense. WebSince temperature affects density, the speed of sound varies with the temperature of the medium through which it’s traveling to some extent, especially for gases.
