Here is the problem, by the way, it is about chemical reactions.

The simple answer is
CH4 (methane) burned in the presence of O2 (oxygen) gives off heat.
the medium answer is
CH4 + O2 → CO2 + H2O
or
CH4 + 2O2 → CO2 + 2H2O
(if you want a balanced equation.)
Combustion is an exothermic (energy releasing) reaction.
If you want a yet more complicated explanation:
The energy stored in the covalent bonds between Carbon and Hydrogen are released during a combustion reaction. The new bonds between Hydrogen and Oxygen as well as Carbon and Oxygen hold less energy. The extra energy is converted to heat and light .

I took earth technological know-how in eighth grade, and then I took biology whilst i grow to be a freshman. actual, I hated biology, it grow to be so uninteresting. Earth technological know-how would be much less confusing if that's like what you discovered in midsection college.
