They move with the wind
hot air rises up
One difference is that a hot-air balloon is uncontrollable and can't be maneuvered in different directions while a plane can move in various directions.
When the air inside a hot air balloon is heated, the molecules gain energy and begin to move faster, causing the air to expand and become less dense than the surrounding cooler air. This lower density air in the balloon then creates lift, allowing the balloon to rise.
A hot air balloon flies because hot air inside the balloon is less dense than the cooler air outside. This temperature difference creates lift, allowing the balloon to rise and float in the air. By controlling the temperature of the air inside the balloon, the pilot can control the balloon's ascent and descent.
A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.
When a balloon is held in hot water, the air inside the balloon heats up, causing the air molecules to move faster and spread out. This increases the pressure inside the balloon, pushing against the flexible walls and causing the balloon to inflate.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
A hot air balloon pilot is called an aeronaut.
The hot air inside the balloon expands, making the hot air balloon fly.
To go up. "The hot air balloon ascended in the morning sky."
There are typically three types of hot air balloon flights: traditional passenger flights where you ride in a basket under the balloon, private charters for special occasions or events, and tethered flights where the balloon is anchored to the ground and doesn't move far.
When a balloon is placed in hot water, the air molecules inside the balloon gain kinetic energy and move faster, causing them to exert more pressure on the walls of the balloon. This increased pressure results in the balloon expanding in order to accommodate the higher volume of air it contains.
