Question

technician a says that compressed natural gas (cng) fuel tanks hold 3600 psi (24,821.1 kpa). technician b says that cng engines tend to emit white smoke, which is water vapor. who is correct?

○ a. technician a
○ b. technician b
○ c. both technician a and technician b
○ d. neither technician a nor technician b

Explanation:

• Compressed natural gas (CNG) fuel tanks typically hold around 3600 psi (24,821.1 kPa), so Technician A is correct.
• CNG engines burn cleaner and the white smoke emitted is indeed water vapor from the combustion process, so Technician B is also correct.

Answer:

C. Both Technician A and Technician B
