    Answer: The correct answer is " decreasing the temperature of the matter".

    Explanation:

    Sound is a form of the energy. Sound wave is a longitudinal wave.

    It needs medium to propagate. It travels faster in solid. It travels slowest in gaseous state. The speed of the sound is more in liquid as compared to gas.

    Sound is form of energy. As the temperature of the matter increases, the particle will gain more kinetic energy. The speed of the sound will get also increased.

    Therefore, the correct answer is " decreasing the temperature of the matter".
