People use hot air balloons to rise high above the ground and be pushed by air currents from one place to another. The diagram shows a hot air balloon.
A type of chemical reaction, called combustion, takes place between propane and oxygen in the burners.
a. Describe a likely result of this chemical reaction that allows a hot air balloon to rise.
b. Describe a design feature the distance a hot air balloon can travel. Explain your reasoning.
Fueled by propane cylinders, gas jets produce the hot air that fills the envelope (similar to ones you might use on a portable camping stove).
WorkingSince heated air rises, hot air balloons are functional. with the rest. As though it were floating in water, the balloon rises as a result of this. The balloon naturally starts to slowly deflate if the air is allowed to cool.The molecules in the air start to migrate and spread out as the air within the balloon is heated, which results in a decrease in the air's density. The heated air is pushed below the cooler, surrounding air. the warm air is pushed upward as a result of this.For more information on hot air balloon kindly visit to
