Hot air balloons have made significant impact in history as early as the Shang dynasty in around 1500 BC when kites with small paper balloons lit with lamps gave signals /messages at night during invasions by Xiung nu. The mention of such hot air lamps with silk fiber material around 3000 BC in China is found in history.
Hot air balloons were used for strategic aerial attacks/observations on enemies by countries like China/Japan that had developed the hot air balloon. It was used for observations in the American civil war & by Germans in WWI for bombing England & London in modified Zeppelin.
Hot air balloons have impact on humans in literature, adventure, sports, war, meteorology, navigation & scientific investigations.
hi
yes it is
The Hot Air Balloon was first created in 1782 by the Montgolfier brothers and then first piloted in late 1783 it was the first successful flying invention of its kind.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Air= air in balloon solid= balloon and basket

The invention and first successful flight of the hot-air balloon
The Hot Air Balloon was first created in 1782 by the Montgolfier brothers and then first piloted in late 1783 it was the first successful flying invention of its kind.
It was the first means by which humans were able to fly.
1780: Bifocal glasses were invented by Benjamin Franklin 1783: invention of the hot air balloon 1784: the safety lock is invented by Joseph Bramah 1785: invention of a parachute by Blanchard

D: The hot air inside the balloon becomes less dense than the air outside the balloon.
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
air is heavier than balloon, air rises
