What is the purpose of using lightweight centrifugal turbopumps in liquid-propellant rockets?
To pump the rocket propellants into the combustion chamber
What is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber?
Inert gas stored in a tank at high pressure
Which of the following is NOT a naturally occurring noble gas?
Carbon
Which of the following is the most reactive noble gas?

Study Notes
Liquid-Propellant Rockets
- Liquid-propellant rockets commonly use a combination of liquid fuel and liquid oxidizer as propellants
Turbopumps in Liquid-Propellant Rockets
- Lightweight centrifugal turbopumps are used in liquid-propellant rockets to inject propellants into the combustion chamber efficiently
Alternative to Pumps in Smaller Engines
- In simpler small engines, a pressurized gas tank is sometimes used instead of pumps to force propellants into the combustion chamber
Noble Gases
- Radon is a naturally occurring noble gas, implying that the other options are not naturally occurring
- Oganesson is a highly reactive noble gas
- The possible reason for oganesson's reactivity is its high ionization energy
