Velocity of sound in a gaseous medium is 330 ms–1. If the pressure is increased by 4 times without change in volume, the velocity of sound in the gas is –
A
330 ms–1
B
660 ms–1
C
156 ms–1
D
990 ms–1
Answer
660 ms–1
Explanation
Solution
At cont. volume
P µ T
\ Vs µP
if pressure becomes 4 times, velocity becomes double.
