How much heat does carbon dioxide, methane and nitrogen gas produce or generate?

Question

Also water vapour too.

This is for a science project, I need to know how much heat is generated from chemicals in landfills sites, incenerators and from chemicals coming out of vehicles.

Answer 1

methane- CH4
nitrogen inert
water(vapour) -H2O
carbon dioxide -CO2
1 BTU- Amount of heat needed to raise 1 Lb of water 1 deg. F
Burning 1 cubic foot methane (natural Gas) - 1000 BTU
air= 2 parts oxygen(O2)+8 parts Nitrogen
amount of air to burn 1 cubic foot methane -10 cubic feet(2 cubic feet of O2)
CH4+2O2=(burned)= CO2+2H2O+heat
Each material has what's called a specific heat or the amount of heat from burning 1 lb of that material(1 lb coal has More potential than 1 lb wood) you would need to know what is being put into the landfill if you are going to burn it in an incinerator.
Organic creatures are only a series of chemical reactions simultaneously occurring. The amount of heat released in the composting materials by converting it to methane is the same amount of energy used in combustion.
Energy can not be created it can only change forms .

Answer 2

Carbon Dioxide and Nitrogen don't produce any heat. Methane doesn't unless you burn it. I'm guessing you're asking about greenhouse gasses. Water Vapor in the atmosphere is the most potent of those.
