Blimps began to be used commonly during World War I, and are still in use today.
Currently blimps are used primarily for advertising, but they are also used for sightseeing flights and as a camera platform.
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.
No, blimps do not contain lithium. All blimps in current service use helium
Goodyear is well known for its blimps. In order for these blimps to float, they contain a lighter than air gas. Hydrogen is to dangerous for this purpose, so helium is used. Thus, helium is the noble gas used by Goodyear.
Yes they do, as helium is lighter than air and blimps will float.
Blimps are filled with Helium which is lighter than air thus causing the blimp to rise like a hot air balloon. Hydrogen used to be used, however Hydrogen is highly flamable resulting in so major accidents.
Modern blimps are used almost exclusively for advertising and/or sightseeing. Historically, blimps have also been used in military reconnaissance roles.

Blimps are used to studie air pollution.
Hydrogen is not used in blimps any longer because it is flammable and dangerous (see: Hindenberg)
yes
The blimps were being used for aerial defenses. They were litterally an obstruction to flying planes trying to attack the landing army.
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.
Boyle's Law is used in flying blimps, as it describes the inverse relationship between the pressure and volume of a gas at constant temperature. By controlling the pressure of the gas inside the blimp, pilots can adjust the volume and thus control the buoyancy of the blimp.
No, blimps do not contain lithium. All blimps in current service use helium
To my knowledge helium is the only practical lift element for blimps. Hydrogen actually works better than helium, and it is cheaper, but it is highly combustible and not used anymore.
Are now known as blimps, they are more used for advertising purposes.
No. Blimps require atmosphere.
