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.
yes it is
Joseph and Etienne Montgolfier are credited with inventing the hot air balloon in the 18th century. They demonstrated the first successful manned ascent in 1783 using their invention.
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.
The Montgolfier brothers, Joseph-Michel and Jacques-Étienne, are credited with inventing the hot air balloon in 1783. They successfully demonstrated their invention with a manned flight in Annonay, France.

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
It was the first means by which humans were able to fly.

The hot air balloon had a significant impact on social and economic development by revolutionizing transportation, enabling faster travel and communication. It also played a role in the development of tourism, scientific research, and military reconnaissance. The invention of the hot air balloon contributed to the growth of industries and provided a platform for innovation and exploration.
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.
A balloon has a certain weight due to the material it's made of. When you blow air into the balloon, the weight of the air inside balances out the weight of the balloon material, making the total weight of the balloon and air the same as the original balloon.
To inflate a balloon, you can blow air into it by using your lungs to push air out of your mouth and into the balloon. Alternatively, you can use a pump to push air into the balloon.
