Many theories can never be proven.
Here are a few examples:
-- The moon orbits the Earth.
-- Gravity pulls all masses toward each other.
-- The Earth orbits the sun.
-- Everything is made of atoms and molecules.
-- Atoms are made of protons, neutrons, and electrons.
-- Electrons moving through a wire make electric current.
-- The center of the Earth is molten iron and nickel.
-- The source of the sun's energy is nuclear fusion in its core.
-- Almost all galaxies are moving away from us.
-- The universe is expanding.
None of these statements can be proven. That's why they're not called
Facts or Laws.

Explanation:
Answer: Combustion is the correct answer.
Explanation:
When a substance combines with oxygen and energy is emitted in the form of heat and light, this process is called combustion.
There are two types of combustion.
1) Complete Combustion : It is a type of combustion in which fuel is quickly react with high amount of oxygen forming carbondioxide, water, heat and light.
2) Incomplete combustion : It is a type of combustion in which fuel is react with low amount of oxygen forming carbonmonoxide, carbon and water.
