Calculate the increase velocity of sound for `1^@C` rise of temperature if the velocity of sound at `0^@C` is `332(m)/(s)`.

Explanation

We know that `(v_1)/(v_2)=sqrt(((T_1)/(T_0)))=sqrt(((237+t)/(273)))`
`v_1=v_0(1+(t)/(273))^((1)/(2))`
`=v_0(1+(t)/(2xx273))=v_0(1+(t)/(546))`
`v_t-v_0=v_0xx(t)/(546)`
Thus increase in velocity per `C^@` is
`=(v_0xx1)/(546)=(332)/(546)=0.61(m)/(s)`
