Question

technician a says that liquefied natural gas (lng) is stored at high pressure. technician b says that lng tanks are much larger than compressed natural gas (cng) tanks for similar range. who is correct?

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

Explanation:

Liquefied natural gas (LNG) is stored at low temperature (not high pressure). Compressed natural gas (CNG) tanks are under high pressure. Also, for a similar range, LNG tanks are smaller than CNG tanks because LNG has a higher energy - density in its liquefied form compared to the compressed form of CNG.

Answer:

d. Neither Technician A nor Technician B
