The velocity of sound in air at `0^(@)C` is 331 m/s. Find its velocity when temperature rises to `91^(@)C` and its pressure is doubled.

Options

A. 330 m/s
B. 165 m/s
C. `330sqrt(2)m//s`
D. `330//sqrt(2)m//s`

Answer

C

Explanation

As there is no effect of change in pressure on velocity of sound in air, and velocity `propsqrt(T)`, therefore, when temperature is doubled, velocity becomes `330sqrt(2)m//s`
