70% to pass

Sweat damage will occur in a cargo hold containing cased machinery when the _______________.

A air temperature of the hold is higher than the temperature of the outside air
B dew point of the outside air is lower than the temperature of the cargo
C dew point of the hold is higher than the temperature of the ship's skin
D outside air temperature is colder than the temperature of the cargo
AI Explanation

The correct answer is C) the dew point of the hold is higher than the temperature of the ship's skin. Sweat damage occurs when moisture in the air condenses on the cooler surfaces of the cargo hold, such as the ship's skin. If the dew point of the air inside the hold is higher than the temperature of the ship's skin, water will condense on those surfaces, leading to sweat damage to the cased machinery. This is the key factor that causes sweat damage in a cargo hold. The other options are incorrect because they do not directly address the relationship between the dew point and the temperature of the ship's skin, which is the critical factor in determining the risk of sweat damage.
