Question

A mixture of hydrogen and oxygen explodes. how is then is the mixture stored in the rocket to be used as fuel.

Answer 1

Hydrogen as a fuel in the rocket

• In rockets, liquid hydrogen is used as the fuel, because of the high value of heat of combustion.
• A mixture of hydrogen and oxygen is used here, oxygen for the combustion of hydrogen, both of them stored as a liquid, as liquid hydrogen$\left({\mathrm{H}}_2\right)$ and liquid oxygen$\left({\mathrm{O}}_2\right)$
• Both liquid hydrogen and liquid oxygen are cryogenic that is, the gases that can be liquified only at extremely low temperatures. so they must be stored at minus $423°\mathrm{F}$ and should be handled with extreme care.
