What happens to the velocity of a sound wave in air if the temperature of the air increases

So as molecules vibrate faster, and heat increases, sound can travel faster; however, the speed of sound can also be affected by humidity and air pressure.

The formula, not factoring in anything else, for the speed of sound with respect to temperature is: v = 331 + 0.6*T where T is temperature.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

give me abc and i will get it for u.
