HEAT
The fuel needs oxygen to burn.
oxygen is needed for fuel to burn
The rocket carries its own supply of oxygen with which to burn the fuel.
hydrogen is an explosive gas and it also needs oxygen to burn
For a flame to burn it needs fuel, oxygen, and heat.
No. Jet engines draw oxygen from the atmosphere to mix and burn with jet fuel, and cannot function in a vacuum. Rockets carry their own oxygen, and can travel in the vacuum of space.
Lungs provide the body with oxygen. Oxygen is not exactly a fuel, but oxygen is necessary in order to burn fuel. Fuel for the body comes in the form of food, and oxygen is necessary to metabolize the food.
Technically hydrogen and helium do not need oxygen to burn, they burn by themselves, otherwise the object that needs burning must have oxygen as a supplimental fuel source.
A mixture of air, heat, and fuel is required for combustion to occur in internal combustion engines. The air provides oxygen necessary for the fuel to burn, while heat from sources such as spark plugs or compression ignites the fuel-air mixture. The combustion of the fuel generates energy that powers the engine.
No. They just take oxygen from the air.
All fuels that 'burn' require air or an oxygen source for combustion. Therefore,fossil fuel also burn in the air.
