Slide Topic Content Notes

Chemical Properties of Natural  Formed from decaying
Gas
organic matter

 90-96% methane

 Other components include
 Ethane
 Propane
 Butane

Natural Gas Is the Simplest  Methane CH4
Hydrocarbon Fuel  Diesel C14H30
 Gasoline C8H18
 Propane C3H8

Physical Properties of Natural  Lighter than air
Gas
 Colorless, tasteless, and
odorless
 An odorant is added for
human detection

 Non-toxic
 Non-corrosive

Flammability Properties of  Ignition temperature
Natural Gas
900 – 1,080°F

 Flammability range 5% to
15% in air
 Below 5% too lean to
burn
 Above 15% too rich to
burn
