Which type of oxygen uses a chemical generator?

• A. Liquid Oxygen
• B. Compressed Oxygen
• C. Solid State Oxygen
• D. Gaseous Oxygen

Answer: (C)

The concept being tested is how oxygen can be produced by a chemical reaction from solid materials. A chemical oxygen generator works by a reaction between solid reactants that releases oxygen gas on demand. Because the oxygen is generated from a solid mixture inside the device, this is described as solid-state oxygen. Liquid oxygen is stored in a cryogenic liquid form and then warmed to become gas; it’s not produced by a chemical reaction inside a device. Compressed oxygen is stored as high-pressure gas in cylinders, not generated on demand by a chemical process. Gaseous oxygen is simply the form of oxygen once it’s released, whether from a tank or a generator, but the generator in question uses a solid reactive material to produce the gas, hence solid-state oxygen.
