Which two hydrocarbons are most commonly used as LP-Gas?
A. Methane and ethane
B. Propane and butane
C. Pentane and hexane
D. Ethylene and acetylene
Answer: B
Explanation: LP-Gas is primarily composed of propane and butane, which provide
its desired vapor pressure and energy content.
What is one implication of LP-Gas's chemical composition for storage?
A. It requires cryogenic storage
B. It needs to be stored in pressurized containers
C. It must be kept in open-air tanks
D. It is stored as a solid
Answer: B
Explanation: Because propane and butane are gases at atmospheric pressure, LP-
Gas is stored in pressurized containers to keep it liquefied.
How does the proportion of propane to butane affect LP-Gas?
A. It changes the color of the gas
B. It affects the vapor pressure and performance in cold weather
C. It determines if the gas is odorless
D. It has no practical effect
Answer: B
Explanation: A higher propane content results in higher vapor pressure, which is
important for proper gas delivery, especially in colder climates.
Which component in LP-Gas contributes more to its high vapor pressure?
