Yes, the two are different. Both are classified as airships or lighter-than-air aircraft, and both apply the principle of trapping a gas that is less dense than "regular" air to provide lift. But there are differences. Hot air balloons are usually non-rigid and open at the bottom, and rise because of the lower density of heated air. When the air in the balloon cools, the balloon loses lift and descends. A blimp is a non-rigid airship that rises because the sealed chambers of the ship are filled with a gas that is less dense than air, like helium or (almost not at all any more) hydrogen. The gas does not have to be heated in order for the ship to stay afloat. In contrast, a dirigible is a rigid airship similar to a blimp, and it uses a gas like the blimp does to gain the air.
blimps are oval shaped
Joey Kasper is going after your mama
um dont ask me omg man
There are various types of air transportation such as commercial aircraft, privet planes, amphibious aircraft, helicopters, lighter than aircraft, hot air balloons, blimps, zeppelins, airplanes, and rockets.
The most obvious are being used every day. Air transportation includes: Airplanes, Helicopters, Hot Air Balloons, Blimps, Rockets, Kites, Parachutes and Birds.

Heavier: Airplanes Gliders Helicopters Lighter: Blimps Balloons
Hot air is used for hot air balloons.
there are many different types: hot air balloons, gas balloons, party balloons, weather balloons and many more complex types of balloons.
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.
