What are the four main types of gas in compressed gas cylinders?

A. Liquefied, non-liquefied, dissolved, and cryogenic
B. Dissolved, propane, reactive, and liquefied
C. Argon, acetylene, cryogenic, and oxygen
D. Flammable, helium, inert, and reactive



Answer :

Final answer:

The four main types of gases in compressed gas cylinders are liquefied, non-liquefied, dissolved, and cryogenic.


Explanation:

The four main types of gas in compressed gas cylinders are:

  1. Liquefied gas: Examples include propane and butane, which are gases that can be liquefied under pressure for easy transport and storage.
  2. Non-liquefied gas: Examples include oxygen and nitrogen, which remain in their gaseous state under pressure.
  3. Dissolved gas: Such as carbon dioxide in water or hydrogen in metals.
  4. Cryogenic gas: Examples are argon and helium, which require extremely low temperatures to be in a gas state.
