Question 208

An outdoor metal storage tank is used to store liquefied petroleum gas (LPG). To prevent the gas from heating up and expanding dangerously on a sunny day, the tank is designed to minimize the absorption of thermal radiation from sunlight.

Which surface texture and color would be best for the outer surface of the storage tank?

A

dull black

B

shiny black

C

dull white

D

shiny white
