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
