Question 385 Deck General

The correct answer is D) the dew point is higher than the temperature of the cargo. When the dew point (the temperature at which water vapor in the air condenses) is higher than the temperature of the cargo, moisture in the air will condense on the cargo, causing water damage to the canned goods in the cartons. This is known as "sweat damage" and is a common problem in cargo holds and storage areas where temperature differences can lead to condensation. The other options are incorrect because A) lower dew point would not cause condensation, B) higher air temperature would not necessarily lead to condensation, and C) lower air temperature would actually prevent condensation from occurring.
