Answer : As the temperature of a medium increases, the speed of the sound wave increases because the particles bump into each other more often.
Explanation :
The dependency of the speed of the sound wave and the temperature of the medium is :
Where
= ratio of specific heat
R is gas constant
T is the temperature
The speed of the wave is directly proportional to the temperature. As the temperature of a medium increase, the speed of the sound increase. The particles start vibrating faster. Hence, they bump into each other.
Hence, the correct option is (A).
