Answer:
v₂₃₁ = 304.4 m/s
v₃₅₁ = 355.5 m/s
Explanation:
The formula used to find the speed of sound in air, at different temperatures is given as follows:
v = v₀ √(T/273)
where,
v = speed of sound at given temperature
v₀ = speed of sound at 0°C = 331 m/s
T = temperature in K
For T = 231 K:
v₂₃₁ = (331 m/s)√(231 K/273 K)
v₂₃₁ = 304.4 m/s
For T = 315 K:
v₃₅₁ = (331 m/s)√(315 K/273 K)
v₃₅₁ = 355.5 m/s
