What is a hot air balloon?

Back

A hot air balloon is a type of aircraft that uses heated air to lift off the ground. The air inside the balloon is heated by a burner, making it less dense than the cooler air outside, allowing the balloon to rise.

Front

What is the role of the burner in a hot air balloon?

Back

The burner heats the air inside the balloon, causing it to expand and become less dense than the surrounding air, which allows the balloon to ascend.

Front

What happens to the air inside the balloon when it is heated?

Back

When the air inside the balloon is heated, it expands and becomes less dense, which causes the balloon to rise.

Front

What is the purpose of the basket in a hot air balloon?

Back

The basket is where passengers and equipment are carried. It is attached to the balloon and provides a safe space for those on board.

Front

How do hot air balloons descend?

Back

Hot air balloons descend by allowing the air inside to cool, which increases its density and causes the balloon to lower.

Front

What safety measures are important for hot air ballooning?

Back

Important safety measures include checking weather conditions, ensuring the balloon is in good repair, and having a qualified pilot.

Front

What is the significance of the weight of the balloon?

Back

The weight of the balloon affects how much hot air is needed to lift it off the ground. A heavier balloon requires more heated air to achieve lift.

Front

What is the principle of buoyancy in relation to hot air balloons?

Back

Buoyancy is the principle that explains why hot air balloons rise. It states that an object will float in a fluid (or air) if it is less dense than the fluid.

Front

What factors can affect the flight of a hot air balloon?

Back

Factors include wind speed and direction, temperature, and the weight of the balloon and its passengers.

Front

What is the importance of the envelope in a hot air balloon?

Back

The envelope is the large fabric part of the balloon that holds the heated air. It must be made of lightweight, heat-resistant material.
