Solution

The correct option is B $V \propto \sqrt{T}$
Speed of sound is directly proportional to the square root of temperature of medium i.e., $V \propto \sqrt{T}$ , where $T$ is temperature of gas on the kelvin scale.

Let V is speed of sound in a gas and T is the temperature of gas on the kelvin scale.

The correct option is B V∝√TSpeed of sound is directly proportional to the square root of temperature of medium i.e., V∝√T, where T is temperature of gas on the kelvin scale.
