Multiple choice general knowledge science & technology As air temperature rises,(pressure constant) sound velocity (speed) ???? decreases increases dsnt change can be random Reveal answer Fill a bubble to check yourself B Correct answer Explanation Sound travels faster in warmer air because increased temperature means higher molecular kinetic energy. This allows sound waves to propagate more quickly through the medium. The relationship is v ≈ 331 + (0.6 × T°C) m/s.
