Step-by-step explanation:
The international festival you are referring to in Albuquerque, New Mexico, is famous for its mass ascension of hot air balloons. The correct answer to your question is A) Hot Air Balloons.
This event is known as the Albuquerque International Balloon Fiesta, and it attracts spectators and balloonists from all over the world. The principle behind the flight of these balloons involves heating the air inside the envelope, or balloon, which makes it less dense than the cooler atmospheric air outside.
This creates a buoyant force causing the balloons to rise. The spectacle of these colorful balloons rising into the sky is a breathtaking sight and a clear example of basic physics in action.
To expand on how hot air balloons work and are able to move smoothly in the air, it's important to understand the relationship between temperature, density, and pressure. At the start of a hot air balloon ride, the balloon is flat as the pressure inside equals that of the outside.
As the air inside the balloon is heated, the molecules move faster and the pressure increases. Eventually, the balloon expands and is ready for takeoff, experiencing a buoyant force that lifts it upwards, allowing it to glide smoothly through the air.
