Question

As the temperature of a medium increases, the speed of the sound wave

increases because the particles bump into each other more often.#
increases because the particles bump into each other less often.
decreases because the particles bump into each other more often.
decreases because the particles bump into each other less often.

Answer 1

Answer:

The speed of sound decreases when it passes from solid to gaseous state of a given medium. In any medium, if the temperature increases, the speed of sound also increases and vice versa. For example, the speed of sound in air at 00C is 331 m s–1 and at 220C it is 344 m s–1.

Answer 2

Answer:

The answer is increases because the particles bump into each other more often.
