Blimps use lighter than air gasses namely hydrogen or helium.
blimps are oval shaped
Blimps are used to studie air pollution.
Yes they do, as helium is lighter than air and blimps will float.

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
Just as a baloon does, but the only diffrence it is a much greater mass. And obviously they don't use air, they use helium which is greater then air.
Blimps are obsolete nowadays. Blimps were always a danger to air travel, as well as its passengers. An example of the dangers of blimps was the Hindenburg tragedy.
Helium's density is less than the density of air, so it floats in air.
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.
