The image shows a labeled diagram of a hot air balloon with two sections: left section is a full labeled diagram of a hot air balloon; the right section explains the mechanism of how hot air and cool air work with arrows. The left diagram labels, from top to bottom, are Parachute valve, Goers, Envelope, Panels, Skirt, Burner, Rope, Basket, and Propane cylinder. The right section contains two balloons showing the different states of air inside, labeled Hot air (light) at the top and Cool air (heavy) at the bottom, with an explanatory note stating "mix propane with air to produce flame to make hot air." The arrow indicates the upward movement of the hot air.
Given the complexity of the image, the above description may not be entirely accurate.

The diagram depicts the configuration of a hot air balloon and its mechanical operation.
Overall, the hot air balloon consists of eight main parts: the envelope, the skirt, the burners, and the basket. It operates using hot air produced by burning propane.
The largest part, the envelope, is made of multiple strips of fabric called gores and panels, and includes a parachute valve. This valve helps regulate the hot air by releasing excess air through a self-sealing flap. The envelope is connected to the basket by the skirt and ropes, with the burners situated between them.
To ascend, a mixture of propane and air is burned to produce a flame, which heats the air inside the envelope. The hot air rises because it is lighter than the cooler surrounding air, lifting the entire balloon.
In summary, the hot air balloon operates by heating air to create lift, with its key components working together to achieve flight.
