Velocity of sound in a gaseous medium is 330ms^(-1). If the pressure is increased by 4 timeswithout causing a change in the temperature, the velocity of sound in the gas is ...............

Answer»

`330ms^(-1)`
`660ms^(-1)`
`156ms^(-1)`
`990ms^(-1)`

Solution :Pressure has no effect on the VELOCITY of sound in the GAS. So velocity of sound remains UNCHANGED.
