Show Answer

Correct Answer :

Option B

Heat and light energy

Solution :

The correct option is Heat and light energy.


Explanation:

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat.


When fuels such as wood, coal, petrol, or natural gas burn, chemical energy stored within the fuel is transformed primarily into thermal energy (heat) and radiant energy (light energy in the form of a flame or glow).


Therefore, when fuels burn, we get both heat and light energy.
