Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
Hot air balloons can fly because hot air rises. When the air inside the balloon gets hot, it rises above the cooler air around it, and it lifts the balloon and any cargo and passengers with it.
Hot air balloons float because hot air displaces cool air in the atmosphere
Hot air balloons are simply that, hot air. Air inside the balloon or envelope is heated, this becomes less dense than the surrounding air therefore creating buoyancy.
Hot Air Balloons work because of the hot air.The hot air rising stays in the balloon and carries it upward.
The hot air inside the balloon expands, making the hot air balloon fly.

Hot air is used for hot air balloons.
The hot water heats the air inside the balloon - making it expand.
Because the air inside the balloon becomes lighter than the air outside
If there is a basket underneath it is a hot-air ballon
Hot air rises because it occupies a greater volume per unit mass of air than cooler air, this makes it less dense. A hot air balloons fire generates hot air which floats inside the balloon, causing it to rise.
The heating of the air through the use of a burner is what makes balloons rise.
Hot air balloons float because hot air displaces cool air in the atmosphere
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
