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
