What is the speed of sound (in m/s) in helium at the normal boiling temperature of water?

Answer 1

Speed of sound in Helium at 0⁰C = 972 m/s

and it changes with change in temp

as

Vt /V0 = Sqrt ( 273+t )/ (273 + 0)

V₁₀₀ = V0 * sqrt (273+100)/(273 +0)

V ₁₀₀ =972 *sqrt (373/273) = 972 * 1.1688 = 1136.16m/s

100C is boing point of water
