If the temperature of the medium is made 16 times its normal value, then the speed of the sound waves will increase by a factor of

Explanation

The speed of sound in a gas is proportional to the square root of temperature (in Kelvin):

v ∝ √T

If the temperature becomes 16 times, then:

New speed = √16 × original speed = 4 × original speed
