PROPANE TEST QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS (GRADED A+)
Question 1
Propane-fueled _________ distribute water from deep wells, rivers, or lakes to
crops in the fields.
Answer: Irrigation pumps
Question 2
What is the specific gravity of liquid propane at $60^\circ\text{F}$?
Answer: 0.504 (Water = 1.000)
Explanation: Liquid propane weighs roughly half as much as water
(approximately 4.20 lbs per gallon at $60^\circ\text{F}$, compared to
water's 8.33 lbs per gallon).
Question 3
What is the specific gravity of propane vapor?
Answer: 1.50 (Air = 1.00)
Explanation: Propane vapor is 1.5 times heavier than air, causing leaks to
sink to lower levels and ground areas.
Question 4
Understanding the weight of liquid propane as compared with the weight of
water helps employees do what?
Answer: Accurately fill cylinders.
Explanation: Knowing liquid density and water capacity (WC) is essential
for calculating maximum allowable fill weights (such as using scale setting
formulas with Tare Weight and Water Capacity) to avoid dangerous
overfilling.
, A hazardous material with liquid specific gravity of 0.618 is _____ than propane.
Heavier
A hazardous material with vapor specific gravity of 1.35 is _____ than propane.
Lighter
Every propane container must be equipped with at least ____ pressure relief valve?
1
Because of the expansion of propane when there is a temperature increase,
cylinders containing propane are filled to about ____ percent of their capacity.
80%
One cubic foot of propane liquid will boil off approximately _____ cubic feet of
vapor?
270
The outside temperature does not affect the vapor pressure inside the container.
False. The outside temperature does affect the pressure
