B. velocity does not change
C. velocity decreases
D. velocity drops to zero

Answer 1

Answer:

A. velocity increases

Explanation:

If the temperature f the air increases then the velocity of the sound wave increases in the air because at the high temperature, air molecules have more energy and they vibrate very fast.

Answer 2

Answer:

the answer would be A. velocity increases.
