Question

Is sound louder in hot or cold air?

Answer 1

Explanation:

Sound louder in hot or cold air: Heat causes air molecules to travel more quickly, making them better equipped to convey a pressure wave than ones that move more slowly. As a result, heat also causes the sound to travel more quickly.

1. Depending on the air's temperature, sound waves move more quickly in warm air and more slowly in cold air.
2. As a result, the wave will propagate through the atmosphere in waves, some of which will move more quickly than others.
3. The heat of the day causes the sound to refract in the other direction, up into the atmosphere and away from our ears. On a steamy summer day, when a thunderstorm approaches, the refraction carries the sound up and away from you, delaying your awareness of it until it is almost directly overhead.
4. In a normal warm environment, a sound wave will tilt and refract toward the earth because the top of the wave moves faster than the bottom because the air close to the ground is colder than the air higher in the sky. Thus, the intensity of the sound increases on the ground making the sound louder.

Hence, the sound will be louder in warm weather.
