An airship uses helium which weighs less than air, and it cancels out the weight of the airship. Hydrogen weighs even less than helium, but it is combustible, so helium is preferred for use in airships.
Airships and Zeppelins and Observation balloons were used successfully in WW1. They were filled with Hydrogen which is the lightest gas but is also explosive when ignited. (Later, airships began to use Helium) The airship flew because it was filled with a gas that was lighter than the air so that it "floated" in the sky. This is the same theory that makes boats float. For an airship to fly, the weight of the airship and the hydrogen contained it in has to be less than the weight of the Air it displaces. In other words, the Airship takes up space in the air and if it weighs less than the air, then it will fly. For it to move forward, the airship had propellors to push it forward. It also had control surfaces on the tail to turn it and help it climb or dive.
The Hindenburg was kept in the air primarily by hydrogen gas, which is less dense than air and provides buoyancy. Its large, gas-filled cells were designed to hold this hydrogen, allowing the dirigible to float. Additionally, the Hindenburg was powered by four engines that provided thrust and maneuverability, enabling it to travel long distances. However, the use of hydrogen, which is highly flammable, ultimately contributed to the disaster that befell the airship in 1937.
The Zeppellin was a rigid framed airship with helium in huge bags. .
The Hindenburg airship, a German passenger airship, famously caught fire and was destroyed during its attempt to dock in Lakehurst, New Jersey, on May 6, 1937. The disaster resulted in the deaths of 36 people, including passengers and crew, and was attributed to a combination of highly flammable hydrogen gas and an electrical spark. The incident marked the end of the airship era and significantly impacted public perception of air travel. The Hindenburg disaster remains one of the most infamous aviation accidents in history.
In 1937, the Hindenburg, a German passenger airship, was tragically destroyed in a fire while attempting to dock in Lakehurst, New Jersey. The disaster occurred on May 6, when the highly flammable hydrogen gas used to fill the airship ignited, leading to a catastrophic explosion that killed 36 people. This event marked the end of the airship era and raised significant concerns about the safety of hydrogen as a lifting gas. The Hindenburg disaster was widely covered in the media, significantly impacting public perception of air travel.
An airship is a lighter-than-air aircraft which can be propelled forward through the air as well as steered.

"Bouyancy". A given volume of helium displaces heavier atmosphere.
The Hindenburg airship was filled with hydrogen gas, specifically about 7 million cubic feet of hydrogen. This highly flammable gas was used as a lifting agent to help the airship float.
an Airship is an aircraft of the lighter-than-air type sustained in the air by gas an aeroplane in a mechanically propelled heavier-than-air flying machine
No, the Montgoflier brothers flew a hot air balloon, radically different from an airship.
The air around the airship has gravitational potential energy as well. When the airship rises, this air is able to go down to occupy the space the airship formally took up.
A hot air balloon is powerless, relying on the winds for locomotion, while an airship has a motor, allowing it to drift with its own power.
from the air around the airship.
A Zeppelin was a rigid dirigible ("steerable") airship filled with a buoyant gas (such as hydrogen or helium) that would allow it to float in the air. Named for the German Count Ferdinand von Zeppelin, who did a lot of the early development of this technology.
A hot air balloon does not have any mean of steering and does not have permanent flotation. An airship has a permanent means of flotation (lighter than air gas bags) and a means of propulsion.
An aeronaut is a person who glides through the air in an airship or balloon.
