CFESA GAS REVIEW QUESTIONS
Where does natural gas come from? - Found in wells drilled deep in the ground
Where does lp gas come from? - It is a byproduct of natural gas
What are three gases often termed LP? - Propane, butane, ethane
Are LP tanks filled with gas or liquid? - Liquid
What happens in a LP tank as gas is drawn off? - Pressure in the tank begins to fall and so does the
boiling point.
Does natural gas have an odor? - No
What is specific gravity of a gas? - The weight of the gas compared to the weight of air, specific

Why is LP more dangerous to work with than natural gas? - It is heavier than air and will fall and
not dissapate
What is the hearing value of a cubic foot of natural gas? - 950btus to 1150btus
What is the heating value of LP gas? - 2500btus
