ACTUAL EXAM TEST BANK| 2 VERSIONS WITH
COMPLETE 450 REAL EXAM QUESTIONS AND
CORRECT VERIFIED ANSWERS/ GRADED A+
Question 1
Propane, as extracted from natural gas and crude oil, has what
physical property?
A) Greenish-yellow color with strong odor
B) Blue tint with sweet smell
C) Odorless and colorless
D) White fog with sulfur smell
Answer: C
Rationale: Propane in its natural state is odorless and colorless.
An odorant called ethyl mercaptan is added during
1
,manufacturing to give propane its characteristic "rotten egg"
smell as a safety warning agent.
Question 2
What device is used on a propane tank to reduce the high
pressure from the container to a usable level for appliances?
A) Excess flow valve
B) Relief valve
C) Regulator
D) Service valve
Answer: C
Rationale: A regulator reduces high propane container pressure
(up to 200+ psi) to a usable working pressure (approximately
11 inches water column or 0.5 psi) for RV appliances. The first
stage reduces to about 10 psi, and the second stage reduces to
11 inches WC.

,Question 3
What is the boiling point of propane at sea level?
A) -10°F (-23°C)
B) -22°F (-30°C)
C) -44°F (-42°C)
D) 32°F (0°C)
Answer: C
Rationale: Propane boils at -44°F (-42°C) at sea level. This
extremely low boiling point means propane vaporizes
immediately when released from a pressurized container, which
is why it can cause frostbite upon skin contact.
Question 4
A property of propane is that, when heated, it:
3
, A) Contracts
B) Expands
C) Becomes solid
D) Becomes heavier
Answer: B
Rationale: Propane expands when heated. For every 10°F that
propane liquid is warmed, its volume increases by
approximately 1.5%. This thermal expansion is why propane
containers are only filled to 80% capacity.
Question 5
When an element or compound changes from the liquid phase to
a vapor, this process is called:
A) Condensation
B) Solidification
