CFESA GAS REVIEW QUESTIONS WITH
COMPLETE SOLUTIONS A+ GRADED
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 gravity of air is 1. Anything lower than one will float.

- Is LP gas heavier or lighter than air - -Heavier
- 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
- How should you check for leaks? - -Soapy bubbles or combustible leak
detectors
- Which gas is more volatile, NG OR LP? - -LP
