The speed of sound in the air is proportional to the square root of the absolute temperature. At 20 °C the speed of sound is 343 m/s. What is the speed of sound at –10 °C? (0 °C = 273 K).

    v=343*sqrt(263/293)

    since they are proportional , then you'll have this:\[\left| T \right|/ speed \] so in this case: \[343/20 = \left| 10 \right|/ \] solve for S by cross multiplying and that's it ^_^

    343/20 = 10/S *

    let s be the speed of light, and T the absolute temperature, then we have: s=k(sqrt(T)), where k is some constant we can find k: k=s/(sqrt(T)) => k=343/(20+273)=1.17 hence, the speed of air at -10°C is s=1.17(-10+273)=307.7m/s hopefully I am right :)

    oh there is a mistake :( k=343/sqrt(20+273)=20.04 therefor s=20.04*sqrt(-10+273)=324.97m/s :)

    it doesn't matter what is k because it is constant and after simplifying it get omited.so let v' be new speed.v'/v=sqrt(T'/T) where T' is new temprture in kelvin. so the last result for v' is 324.966 m/s

    you should, the simpler you explain it , the clearer you see the problem and the clearer the other person sees it too + the more organized. To solve a problem, we take each step at a time = this is called organization = simplicity :)

    I think there is one little mistake in the formula you gave, that you consider S to be proportional to T, while it's proportional to its square. right?
