Submarines typically use air tanks. Oxygen is very dangerous and very flammable. It's use is very limited on submarines for that reason.
Yes Germany did use tanks during world war 1, they use tanks alone with airplanes, gas masks, and submarines
Submarines change their depth by use of ballast tanks. To dive, they open their tanks so that they become filled with water. They also angle their dive planes. To surface, they pump the water out of their tanks and fill them with pressurised air.
No there were no tanks planes OR submarines in ww1. My friend Dennis ate them all.
The same way they do today, they took saltwater into tanks while underwater, evaporated out the salt and electrolyzed the oxygen out of it. They also carried tanks of compressed air in the submarine.
Chemicals aren't used to make O2 on board modern submarines; they use electrolysis to separate the Hydrogen and Oxygen in DI water, then store the O2 in tanks outside the pressure hull. The hydrogen is bled overboard as tiny bubbles (in the wine.... make me feel happy...make me feel fine).
Oxygen tanks should be kept in a well-ventilated area. Oxygen tanks should not be kept in the trunk of a car. "No Smoking--Oxygen in Use" signs should be used to warn visitors not to smoke near the patient.
Astronauts bring tanks of oxygen with them when they go into space. The space suits they use to make space walks also have small oxygen tanks on them.
By sinking them!
periscopes are used for submarines and war tanks
Submarines have ballast tanks in them.........when it has to go deep down, the ballast tanks are filled with water, which increases its average density in regard to water(Relative Density).....and when it has to come up to the surface it empties the ballast tanks...and it rises. That's it.

Firefighters typically get oxygen tanks from their fire department or fire station. These tanks are filled with compressed oxygen and are essential for providing breathable air to firefighters in hazardous or smoke-filled environments.
