2. OXIDISER AND FUEL :
•An oxidizer is a substance that supplies
oxygen to a fuel, allowing it to burn. A fuel is
a substance that provides energy through
combustion.

4. Example:
•Example of a fuel-oxidizer combination is
liquid oxygen (oxidizer) and kerosene (fuel)
in a rocket engine. The oxidizer and fuel are
stored in separate tanks and are pumped
into the combustion chamber where they
mix and ignite, generating high-pressure
and high-speed exhaust gases that provide
the thrust needed for propulsion.

5. APPLICATIONS:
•Rocket propulsion: Liquid oxygen (LOX) is
used as the oxidizer with fuels such as
kerosene or liquid hydrogen to power rocket
engines.
•Combustion engines: Air is used as the
oxidizer with gasoline or diesel fuel to
power internal combustion engines in
vehicles, boats, and aircraft.

6. DISADVANTAGES:
•Hazardous nature: Oxidizers and fuels can be
highly reactive and flammable, which can lead
to fire or explosion if not handled properly.
•Environmental impact: The combustion of fuels
can release pollutants and greenhouse gases
into the atmosphere, contributing to air
pollution and climate change.
