Jacques Charles's accomplishments in the field of aviation, specifically his development of the hydrogen balloon, revolutionized air transportation. His successful flight in a hydrogen balloon demonstrated the possibility of human flight in controlled, lighter-than-air vehicles, paving the way for future advancements in aviation technology and influencing the development of modern air travel.
He 'flew' in helium balloons. Volume increases as temperature increases. In a hot air balloon temp increases so volume increases and some air must leave the balloon. The balloon now has lift because it weighs less than the cold air outside the balloon, just like buoyancy of a boat in water.
