Question

Which fuel is used in rocket ?Why?

Answer 1

In rockets we use fuel that can be burned rapidly. So any material or mixture of materials that can be burned with controlled combustion to give very large thrust and to produce large volumes of gas at high pressures and temperatures can be used . It includes mono propellants (hydrogen peroxide and hydrazine), liquid bipropellant fuels (organic fuel and oxidizer), and solid propellants (mixed oxidizer-fuel in a propellant grain) .
