Why do you hear better in an elevated during hot days?
Answer : A. Because of the particles of the air during hot days travel faster
Explanation : Air molecules have more energy at higher temperatures, which means they vibrate faster. This allows the sound waves to also travel faster because they are propelled by collisions between the molecules.
