Hello!
When butane reacts with oxygen, the temperature of the surrounding area increases.
The chemical equation for this reaction is:
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
This is a combustion reaction. Combustion reactions are highly exothermic, meaning that there is a high amount of energy that is released from the breaking of the chemical bonds and the oxidation of butane to carbon dioxide. This energy is released in the form of heat, increasing the temperature of the surroundings.
Have a nice day!
