Zeppelins were developed but not widely used then.
Germany
The first large scale and successful use of poison gas was at the Second Battle of Ypres. Germany released chlorine gas in a light wind that took it into trenches controlled by French forces, causing them to flee. Canadian forces filled in the gap created and counterattacked through further gas attacks, eventually winning the battle.
Gas masks were gradually developed in the 1800s and the exact year you need is in the link below.
Poison Gas was invented in 1915, Germans used it in Trench Warfare. Gas masks were eventually given to soldiers but people can argue that Poison Gas was one of the most deadly weapons in WWI. Germans invented U-Boats (submarines) to take down enemy ships filled with soldiers and military supplies. Britain created the first tank in 1916, they were mostly used in Trench Warfare but had limited use because they often broke down. Im not sure who first started to use airplanes in WWI but i do know that the Germans invented "Zeppelins" in 1915, Zeppelins were gas filled balloons used to bomb places.
Germany. They used Chlorine gas in the second battle of Ypres.
Zeppelins, filled with hydrogen gas at first, making them highly flammable.

Hydrogen was a highly flammable gas but as they became aware of it they filled the dirigibles with helium instead, which is a non-flammable gas.
The United Kingdom ( England, Scotland And Wales) Germany invented gas.

Because helium was not disponible in Germany before the war; USA refused to help Germany with the necessary volume of helium.
are coral reefs can be gas of ships?
Helium was more suitable but not available in Germany before the war.
They are filled with air, which is a mixture of gasses, so yes they are filled with gas
They are filled with helium gas. They used to be filled with hydrogen gas but that proved to be deadly at times.
