Why does a hot air balloon fly?
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.
How does a hot air balloon return to Earth's surface?
A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.
What causes a hot air balloon to stay afloat?
A hot air balloon stays afloat because hot air inside the balloon is less dense than the surrounding cooler air, creating lift. As the air inside the balloon is heated, it expands and becomes lighter, causing the balloon to rise. By controlling the amount of hot air in the balloon, the pilot can control the altitude.
How does a hot air balloon go down?
A hot air balloon can descend by either releasing hot air from the balloon envelope or by opening a vent at the top of the balloon to allow some of the hot air to escape. This reduces the buoyant force that is keeping the balloon in the air, causing it to descend slowly. The pilot can control the descent rate by carefully managing the release of hot air.
Why do hot air balloons work?
Hot air balloons work by heating the air inside the balloon with a burner, which makes the air less dense and causes the balloon to rise. This is because the hot air inside the balloon is lighter than the cooler air outside, creating a buoyant force that lifts the balloon. By controlling the temperature of the air inside the balloon, the pilot can control the altitude of the balloon.

How does the volume in a hot air balloon change?
The volume of a hot air balloon increases as the air inside the balloon expands when it is heated. As the balloon ascends and the air temperature decreases, the volume of the air inside the balloon decreases as well. The pilot can control the altitude of the balloon by controlling the temperature of the air inside.

What are the forces acting in a hot air balloon ride?
In a hot air balloon ride, the main forces acting on the balloon are lift, gravity, and drag. The hot air inside the balloon is lighter than the cooler air outside, creating lift. Gravity pulls the balloon downwards, and drag opposes the balloon's forward movement through the air. Flight control is achieved by controlling the amount of hot air in the balloon.
Why does pulling the cord have this effect hot air balloon?
Pulling the cord on a hot air balloon opens a valve that releases hot air from the balloon, causing it to sink. By releasing hot air, the balloon becomes less buoyant and starts descending. This allows the pilot to control the balloon's altitude and descend to the desired landing spot.
What helps a hot air balloon go higher?
A hot air balloon goes higher by increasing the temperature of the air inside the balloon. When the air inside the balloon is heated, it becomes less dense than the surrounding air, allowing the balloon to rise. Pilots can control the altitude by adjusting the heat to maintain the desired height.
What is the parachute valve cord for in a hot air balloon?
The parachute valve cord in a hot air balloon is used to control the opening and closing of the parachute valve at the top of the envelope. This valve helps release hot air to control the altitude of the balloon by allowing the air to escape. The cord is pulled to open the valve, releasing hot air, and released to close it.
What forces on hot air balloon?
A hot air balloon is lifted by the force of buoyancy, which is created when the hot air inside the balloon is lighter than the cooler air outside. The balloon is also affected by wind currents, which can push it in different directions. Additionally, the burners used to heat the air in the balloon generate thrust to control the altitude and direction of the balloon.
What happens if a hot air balloon ascends too high?
If a hot air balloon ascends too high, the air pressure decreases and the balloon may burst or lose control, potentially causing it to crash.
