Hot Air Balloon

A hot air balloon is a type of aircraft that flies using the principle of buoyancy. It consists of three main parts:

Envelope – the large fabric balloon that holds hot air.

Burner – a device that heats the air inside the envelope using propane gas.

Basket (or gondola) – the compartment (usually wicker) where passengers and the pilot stand.

How It Works:
When the air inside the envelope is heated, it becomes less dense than the cooler air outside.

This causes the balloon to rise because warm air is lighter than cold air.

To descend, the pilot allows the air to cool or releases hot air using a vent.

Hot air balloons are commonly used for recreational flights, festivals, and sometimes aerial photography. The first successful manned flight in a hot air balloon was made by the Montgolfier brothers in France in 1783.
