Why use heat in a hot air balloon?
Because hot air rises. And I assume because burning fuel to create the hot air is easier, perhaps a lot lighter as well, and definitely cheaper than constantly buying helium. Although blimps used that method.
What is the gas used in hot air balloon?
Air - a mixture of nitrogen, oxygen, carbon dioxide and other gases. When heated, air becomes less dense and so it will float in cooler (= more dense) air, giving the balloon its lift.Airships and blimps are different to hot air balloons in that they gain lift from an envelope (the balloon) filled with a gas that is lighter than air. In the past, this was hydrogen but use of this gas was stopped due to its extremely flammable nature and helium is now used instead.Used gasses in balloons: helium, hot air, hydrogen.
Why do hot air balloons rise?
Hot air is less dense than cold air, thus hot air rises in cold air. Hot air balloons trap the hot air, thus creating an upward force at the top of the balloon. With sufficient mass, the upward force upon the balloon can overcome gravity, lifting both the balloon and the burner (used to heat the air) up off the ground. To lift people you need a much larger envelope to hold the required mass of hot air to overcome the gravitational pull. The air in the balloon is heated by a burner to make it expand (become less dense). They have a lever that they pull that releases fire.The fire makes hot air and it hits the top of the hot air balloon that makes it rise. Helium-filled balloons are more commonly known as blimps (airships) which do not use burners because helium is lighter-than-air to begin with. Helium replaced hydrogen which was originally used in blimps. Using burners on hydrogen would have been foolhardy at best (refer to the Hindenburg disaster).
How the blimp is different from the hot air balloon?
Both, a balloon and a blimp, are considered aircraft, and fall under the category of "Lighter Than Air Aircraft" as regulated by the F.A.A. They both have a huge bag of some sort of gas that is lighter than the air around it, and therefore creates lift. Since the Hindenburg, Helium has been the lifting gas of choice, as it is an inert gas, therefore safe and manageable. Some balloons use hot air for lift for shorter, less expensive flights. Suspended from this bag, called the "Envelope", is the passenger compartment. This "Gondola" or "Car" also houses the Pilot, and controls for the aircraft. That is where the similarity of the two part ways. To simplify the big difference, balloons climb quite readily, but have no means of propulsion, therefore primarily drift in the ambient air. Their path and destination are determined by how the Pilot uses the existing winds. Most times the winds travel at different directions in different altitudes and your Pilot will navigate using these variations to the destination. Truly, an artform. However, if the entire air mass is moving to the east, guess what? You are going east. On the other hand, a blimp has engines and propellers, and therefore is steerable, even against the wind, to the destination. Blimps almost always land at airports, whereas, balloons almost never do. In other words, blimps operate like other aircraft for point-to-point navigation, only slower, and lower. With balloons, you are blissfully and romantically casting your fate to the wind. A finer, more elegant, adventure is hard to find.

What air do blimps use?
Blimps use lighter than air gasses namely hydrogen or helium.
What are the differences between hot air balloons and blimps?
blimps are oval shaped
Has helium ever been used in blimps?
Yes, helium has been used in blimps as a lifting gas. Helium is less dense than air, which allows it to provide buoyancy and help the blimps stay afloat. However, today, most blimps use a combination of helium for lift and air for control and propulsion.
Is lithium in blimps?
Yes, lithium can be used in the form of lithium-ion batteries in blimps for electrical power. These batteries are lightweight and have a high energy density, making them suitable for air transportation applications.
What makes helium great to use in balloons and blimps?
Helium's density is less than the density of air, so it floats in air.
Do they still use helium in blimps?
Yes, helium is still commonly used in blimps due to its low density and non-flammable properties, making it a safe option for lifting aircraft. Helium provides the necessary buoyancy to keep blimps afloat and is widely used in the aerospace industry for this purpose.
Why do they use helium gas in blimps?
Helium has a low density and causes balloons and blimps to float
What is the difference between blimps and airplanes?
Beside the actual design of course, the difference is that airplanes use their engines/propellers and wing to create air flow and fly while blimps, zeppelins, and the like use hot air to propel themselves up and increase or decrease hot air in the balloon to go up or down. This is the main difference between the two aircrafts.
How do blimps float?
Blimps float because they are filled with a gas that is less dense than the surrounding air, typically helium or hydrogen. This creates lift, allowing the blimp to stay airborne. By adjusting the amount of gas in the blimp, pilots can control its altitude.
